Project Title: | Gradient diffusion-attenuated NMR spectroscopy for the analysis of multi-component mixtures |
Investigator(s): | Brown GD |
Department: | Chemistry |
Source(s) of Funding: | Other Funding Scheme |
Start Date: | 12/1994 |
Abstract: |
Spectroscopic analysis of multi-component mixtures has always required a physical separation of the components by some chromatographic technique prior to the acquisition of a characteristic spectrum from each component. In recent years there has been a poliferation of "hyphenated" techniques based on this very principle. The modern capability to generate magnetic-field gradients in NMR Spectroscopy opens up the possibility of differentiating compounds by their diffusion characteristics. The project aims to investigate whether this molecular property can be applied to resolve different components when present simultaneously in the same mixture. If successful, NMR analysis of complex mixtures would then be as simple a matter as NMR analysis of ind ividual compounds, and the need for prior chromatography will have been removed, resulting in greater simplicity and wider applicability of NMR in the analysis of multi-component mixtures. |

Project Title: | Electrochmeical oxidation of glucose |
Investigator(s): | Chan GKY |
Department: | Chemistry |
Source(s) of Funding: | Outstanding RGC Projects |
Start Date: | 09/1998 |
Abstract: |
The electrochemical oxidation of glucose on some inorganic electrodes will be studied. These electrodes appeared to have better activities than others reported in the literature. Investigations are planned to identify the oxidation products and hence the mechanism of the glucose oxidation process. Furthermore kinetics studies will be made on well characterized surfaces so that the effects of surface morphology and composition on catalytic activity can be determined. The results of these studies will help in the design of better catalytic electrodes for glucose oxidation and will be used to help in the development of a glucose sensor. The applications of these electrodes as glucose sensors will be assessed. Tests will be made for determination of glucose concentration in serum. Anti-fouling, anti-interference, linearity, and selectivity of a glucose sensor using the new catalyst will be evaluated. |

Project Title: | Site-selective Modification of Proteins Catalyzed by Water-Soluble Transition Metal Complexes |
Investigator(s): | Che CM |
Department: | Chemistry |
Source(s) of Funding: | Seed Funding Programme for Basic Research |
Start Date: | 02/2005 |
Abstract: |
Objectives and significance of the research proposal to be undertakenSite-selective modification of proteins in aqueous medium is of significant importance in protein research and materials science, as it provides an indispensable tool for the studies of protein-protein and protein-drug interactions as well as the synthesis of novel nanoparticle-protein conjugates. Despite the great advancement of chemical synthesis in the last century, there is only a handful of synthetic methods that can be applied on the modifications of proteins (as most of the reactions are not compatible with aqueous medium). In this connection, there is a growing need for developing new reactions that can selectively modify biologically important biomolecules in aqueous medium. Transition metal catalysts are of particular interest in organic synthesis as their reactivities and selectivities can be fine-tuned by judicious choice of metal ions and structurally diverse ligands. Recently, some new transition metal-catalyzed atom/group transfer reactions have been developed for modification of peptide backbone in aqueous medium. However, only a few examples have been utilized for protein modification. We envision that to develop new reactions that can modify biomolecules in a selective manner, it is important to introduce structural motifs to the auxiliary ligands of metal-based catalysts for molecular recognition of the biomolecular targets.Over the years, we have extensively investigated metalloporphyrin-catalyzed atom/group transfer reactions. By virtue of the structural diversity of the macrocyclic ligand, steric and electronic properties of metalloporphyrin catalysts can be fine-tuned for stereo- and enantioselective reactions. We envisage that metalloporphyrins would have tremendous potential to be the future catalysts of choice for site-selective modification of biomolecules. Recently, we have developed two water-soluble ruthenium porphyrin catalysts by attaching hydrophilic groups such as glycan and polyethylene glycol (PEG) at the peripheral phenyl rings of porphyrin ligands for catalytic carbenoid reaction in aqueous medium. Preliminary results have shown that the ruthenium glycosylated porphyrin catalyst was effective for site-selective cyclopropanation of styrene-conjugated proteins including ubiquitin as confirmed by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometric analysis. To our knowledge, this is the first example in which metalloporphyrins could be used to catalyze site-selective bioconjugation reactions. These modified-biomolecules would be valuable tools for proteomic and medicinal studies as well as materials science. We foresee that the application of transition metal catalysts on biomolecule modification will be the upcoming frontier area of chemical research in this century. With our existing research capability and the promising findings, we aim to (1) extend the scope of the water-soluble metalloporphyrin catalysis for site-selective protein modification research, (2) explore other carbeniod transfer reactions, and (3) apply the newly developed carbenoid transfer reactions for the conjugation of small molecules to biologically important biomolecules. |

It is proposed to combine laser vaporization/reaction free jet expansion source for producing the metal compound in gas-phase and optical-optical double resonance (OODR) spectroscopy to study electronic states near the dissociation limit. The goal of this research is to determine the vibrational and rotational, constants for electronic transitions of transition metal compounds. Supersonic expansion is a well-known technique for cooling the internal degrees of freedom of molecules far below the normal boiling point, while maintaining the molecule in gas-phase. Recently, this technique has been combined with laser vaporization/reaction source to produce high-boiling point transition metal compounds and dimers. A localized pulse heating of the metal or metallic compound by focused laser irradiation is technically superior to the extreme temperatures required to vaporize metal compounds. An intense pulse beam source of gas mixtures provides chemicals for the reaction with vaporized metal atom. The technique of laser vaporization/reaction with supersonic expansion has been proven to be successful in forming metallic compounds in gas-phase at low temperature. In OODR spectroscopy, two photons of different wavelength undergo absorption in a three-level system. Both of these photons are either from the near infrared, visible or ultra violet or each is from a different one of these spectral regions. When these two photons are arranged to pass each other in opposite directions, a spectrum with sub-Doppler resolution could be obtained. The OODR process with two photons absorption in two steps reaching for the high-lying electronic state is called cascade OODR process, which permits the study of these high-lying electronic states that are not reachable either because of symmetry characteristics from the ground state or due to limitation in photon energy with only one photon. The molecules excited are those in the specific lower level to upper levels of various electronic states, so excitation is selective for this transition or a group of transitions. Spectroscopy involving a double resonance technique in which transitions are detected through fluorescence is of advantages. This is because in the optical region the detection of fluorescence photon against a background of zero or little scattered laser light is intrinsically much more sensitive than the detection of direct absorption of laser light. The applicant has an on-going programme and long history of studying transition metal containing species in the visible and near infrared region using laser induced fluorescence techniques with an argon ion pump dye laser system. It is proposed here to combine the laser vaporization/reaction supersonic expansion technique with OODR spectroscopy to study electronic transitions of transition metal compounds. Such a combined approach should be fruitful for studying the high-energy electronic states because it solves the problem of getting the high melting point compounds in the gas-phase and performing high-resolution study. In this project, a widely tunable pulsed dye laser and narrow linewidth laser source will be used to excite the metal compound molecules and the detection is by fluorescence spectroscopy. Most of the high-lying electronic transitions of transition metal compounds are not known, once these molecules are produced in a supersonic jet, an extensive spectral search for the electronic transitions is necessary. |

Abstract: |
Protein glycosylation has been recognized as one of the most common protein post-translational modifications, especially N-linked glycosylation, which plays important roles in various virus-receptor interactions.[1] Determining the exact residues that are glycosylated is an essential part in understanding protein function. Identification and sequence information of the specific proteins expressed are highly desirable but difficult to acquire because of small sample sizes, low concentrations and the requirement of sensitive analytical techniques. The ability to identify and determine proteins in femtomole quantities is rapidly being realized with the advent in the late 1980s of electrospray (ESI) and matrix-assisted laser desorption/ionization (MALDI), ionization techniques for mass spectrometry that are sensitive and well-suited for proteins.[2] The advent of the aforementioned soft ionization techniques recognized by the 2002 Nobel Price in chemistry in which revolutionized the field of mass spectrometry by enabling the introduction of very large non-volatile biomolecules into the gas phase. These techniques are used routinely to introduce peptides and proteins into the gas phase, in the form of closed-shell protonated ions, [M + nH]n+ or species cationized on metals, followed by structure determination using tandem mass spectrometry (MS/MS). Protein MS, in combination with high-resolution separation techniques and database searching, is being applied to identify proteins via their tryptic maps and partial sequence data. However, the genetically determined sequence of the amino acids defines the structure and ultimately the function of the protein. Many important proteins are post-translationally modified, such as the spike glycoproteins from Severe Acute Respiratory Syndrome (SARS) coronavirus and Gp120 from Human Immunodeficiency Virus (HIV), an essential step rendering them functionally active; post-translational modifications are not apparent from genomics sequence or mRNA expression data. The detection of protonated peptides via ESI or MALDI-MS has been recognized as key technology in the identification of proteins and it post-translation modifications. A complete glycosylation sites mapping of glycoproteins in complexes biological sample could be difficult to acquire owing to the observed peptide ions from ESI or MALDI-MS are sequence, MS ionization and charge dependent as a result of bottom necking in complete N-Glycosylation sites identification. We ascribe the favorable formation of protonated peptides may be due to the relatively high proton affinity and ionization efficiency of particular peptides.In this proposal, we aim to (1) study the effects of sequential specific and non-specific enzymatic digestion, ionization techniques and sample purification on the protein coverage; (2) develop methodologies to confirm and screen the potential N-glycosylation sites using tandem mass spectrometry; and (3) develop an appropriate method for the extraction, enrichment, and purification of glycopeptides. |

Abstract: |
Recent work done at Respiratory Medicine, HKU, had shown the potential role of genetic polymorphisms of glutathione-S-transferases GSTM1, GSTT1 and GSTP1 in susceptibility to lung cancer in Hong Kong Chinese and GSTT1 null genotype was found to associate with an increased risk for lung cancer in non-smoking Chinese in Hong Kong (Lung Cancer (2004) 45, 155-160). This leads to the need in assessing the role of combined genetic polymorphisms of related enzymes in elucidating the etological factors of lung cancer amongst non-smoker in Hong Kong, particular for female in Southern China, as little work has done in this area before. In addition to genetic research, investigation on changes in antioxidant enzyme activities and oxidized glutathione (glutathione, GSSG) in erythrocytes from patients with asthma has been conducted, showing that asthma is accompanied by an alteration in systemic antioxidant status due to possible oxidative stress (J. Allergy & Clinical Immunology, 2004, 114(2) 260-264). Through previous research collaboration between Chemistry Department and Dalian Institute of Chemical Physics, we have developed methodologies based on microchip electrophoresis for genotyping of -6A/G functional polymorphism in the core promoter region of Angiotensingen Gene (Electrophoresis, in press), as well as an ultra-rapid method for simultaneous determination of Reactive Oxygen Species (ROS) and Reduced Glutathione (GSH) in Apoptotic Leukemia cells (Electrophoresis, under review). The genotyping methodology developed based on microchip electrophoresis can be extended for determining other lung cancer related genes such as Interlukin 11G and Interin 1 and the ultrarapid assay for ROS and GSH by microchip electrophoresis (results obtained within 27s) can be adopted after development for analysis in plasma. They will provide suitable methodologies to enhance the work done in respiratory medicine in cancer and asthma research. The objectives of the present proposal are developing the microchip electrophoresis methodologies for the analysis of ROS and related species in plasma, as well as for the determination of genes related to lung cancer such as Interlukin 11G and Interin 1. The tools available will enable conducting a survey of selected population to understand the route from genetic makeup to expression of antioxidants through protein analysis. The information obtained is essential to map the path for carcinogenesis for lung cancer and to understand the effect of antioxidants on asthma patients, producing results needed to identify high risk group and to guide therapeutic treatment for intervention to block pathogenesis development for asthma and cancer patients. |

Abstract: |
The main objective is to develop the two nanotechnologies, namely Capillary Nano-particle Sizing Technology (CENST) and the Electrophoretic Nanocoating Technology (ENT), which are previously supported by the Innovation and Technology Fund (ITS/125/01), to new processes to produce specific products in the manufacturing of automobile parts and accessories, a rising industrial sector at the Pearl River Delta area. There are three main focus areas for developing the product oriented processes using the two nanotechnologies developed.The first focus area is to develop a transparent polymeric coating layer with main focus on corrosion protection of aluminium and magnesium based alloys. They can be used for functional coating or for coating parts with decorative appearance. Fundamental investigations have to be performed to study the pore structure of the protective oxide layer formed during industrial production of aluminium and magnesium alloys and to investigate the size distribution effect of nano-emulsion on coating formed at various pore structures as identified. The composition of the electrophoretic bath needs to be developed and the working conditions of ENT established under the best performance. In addition, the working conditions of CENST needed to be optimized for QA/QC of the ENT processes. The second area is developing coating using nanoemulsion and a mixture of dyes to achieve a combined function on corrosion protection and decorative finish. It will aim at achieving both functions using a single coating process. The third area will focus on the co-deposition of nano-composites with metal particles, dyes and nanoemusion to produce desirable patterns for highly decorative parts. All the processes developed use the environmental friendly water-based system. Blending nano-emulsion with other polymer particles will be investigated in the above three processes to produce an Interpenetration Network structure to achieve a desirable coating layer with suitable thickness and to reduce cost. |

Project Title: | Time-Resolved Resonance Raman and Density Functional Theory investigation of the structure, properties and chemical reactivity of selected weakly bound species containing S and/or halogen atoms |
Investigator(s): | Phillips DL |
Department: | Chemistry |
Source(s) of Funding: | Merit Award for RGC CERG Funded Projects |
Start Date: | 09/2003 |
Abstract: |
The proposed study will provide important characterization and insight into the structures, properties and chemical reactivity of selected radical cations, radical anions and neutral species containing weak bonds formed from a singly occupied sulfur or halogen p orbital and lone pairs of S or halogen atoms. This fundamental work will lead to an improved understanding of the likely role of these species in the biological activity of many proteins, enzymes and antibiotics as well as in protection mechanisms for biological systems attacked by ionizing radiation or other kinds of free-radical damage. The propossed work for halogen containing systems should help elucidate the likely role of these types of species in environmental and atmospheric chemistry. Comparison of the 2c-3e bonding in the radical cation and anion complexes to those of the isopolyhalomethane and halogenated solvent-halogen atom complexes that are neutral species should enable an improved understanding of how the structure, properties and chemical reactivity vary with oxidation state for these loosely bound complexes. |

Project Title: | Bismuth and Zinc Complexes as Antiviral and Anticancer Agents |
Investigator(s): | Sun H, Zheng B |
Department: | Chemistry |
Source(s) of Funding: | Seed Funding Programme for Basic Research |
Start Date: | 02/2005 |
Abstract: |
Both bismuth (Bi) and zinc (Zn) compounds have long been associated with medicine, and particularly used as antimicrobial agents in clinical [1,2]. For example, colloidal bismuth subcitrate (De-Nel®) and rantidine bismuth citrate (Pylorid®) have been recommended as a standard treatment for Helicobacter pylori infection and peptic ulcer together with antibiotics [3]. Zinc compounds (e.g., Zenullose) were also showed effective for the treatment of the common cold, a disease caused by rhinoviruses although the mechanism of action remains unclear. Since zinc is an essential element and bismuth is nearly non-toxic, in contrast to other heavy metals, it would be very important and interesting to develop bismuth- and zinc-containing compounds as potential either antiviral or anticancer agents. Our preliminary work has showed that the clinically used bismuth compound (Pylorid®) can effectively inhibit the production of SARS-CoV in vitro (FRhk-4 cells) with extremely high selectivity (EC50: CC50= 5.9 µM: 5 mM). Zinc compound was recently found to be active against 3C-like proteinase (3CL), an essential protein fore the life cycle of SARS-CoV [4]. Promising anticancer activities of bismuth and zinc complexes were also demonstrated [5]. Using our initial work as a foundation, we will combine the expertise of PI and Co-I to design and synthesize bismuth- and zinc-containing complexes as antiviral and anticancer agents and explore the structure-and-activity relationship. This study will not only improve our knowledge of the medicinal chemistry of bismuth and zinc (as novel antiviral and anticancer agents), but also offer a basis to attract an external funding. We intend to achieve three separate but closely related objectives:(A) To design and synthesize Bi- and Zn-containing complexes for biological tests;(B) To study biocoordination chemistry of these complexes under biologically relevant conditions;(C) To screen antiviral and anticancer activities in different systems. |

Abstract: |
The human telomerase reverse transcriptase (hTERT) is the catalytic subunit of telomerase holoenzyme as well as the rate-limiting component of the telomerase enzyme complex. By reverse transcribing the telomerase RNA component (hTR) to the telomeric DNA sequence, hTERT synthesizes and elongates the terminal telomeric DNA, thereby counteracting the cellular senescent program orchestrated by telomere shortening. Thus, hTERT activation is essential for cell immortalization, malignant transformation (Meyerson et al 1997; Sonoda et al 2001), and cancer cell survival (Hahn et al 1999; Zhang et al 1999)The hTERT is a 127-kDa protein with 1132 amino acid residues (Meyerson et al 1997), containing a hTR specific binding domain at its N-terminus (Beattie et al 2000; Lai et a; 2001) and a RT-domain at the central region (Meyerson et al 1997; Friedman et al. 1999). Both of these functional domains are required for the reverse transcriptase activity. hTERT also needs to be translocalized to the nucleus and targeted to the telomere ends to be functional. Nuclear translocation has been shown to be regulated by the interactions between the hTERT C terminus and the protein 14-3-3 (Seimiya et al., 2000). However, the mechanism for the telomere end targeting of hTERT is not understood..We have constructed a polypeptide containing the C terminal 27 kDa hTERT (hTERTC27). We recently showed that hTERTC27 is capable of nuclear translocation and telomere-end targeting. Ectopic overexpression of this polypeptide in hTERT positive HeLa cells specifically causes telomere dysfunction and rapid chromosome end-fusion, resulting in cell apoptosis and senescence (Huang et al 2002). The phenotype is similar to that of the dominant negative mutant of the telomere-binding protein TRF2 (DN-TRF2). DN-TRF2 interferes with the binding of TRF2 to telomere and rapidly induces telomere dysfunction and cell growth inhibition without affecting the telomerase enzyme activity (Steensel et al 1998). Therefore, hTERTC27 may act by disrupting the normal function of the hTERT C-terminus, which may include binding to various components at the telomere end and maintaining the telomere structure.The objective of the proposed works is to understand the structure-function of hTERT C-terminus by determination of the three-dimensional structure of hTERTC27 using NMR spectroscopy. Our proposed works will address the following questions:(1) What is the structure of hTERTC27? (2) How does the structure of hTERTC27 related to the function of hTERT? We aim at identifying the functional motifs, elucidating the molecular targets and mechanisms for hTERTC27 induced telomere dysfunction. |

Project Title: | Chiral Alcohol Catalyzed Asymmetric Oxidation Reactions |
Investigator(s): | Toy PH |
Department: | Chemistry |
Source(s) of Funding: | Seed Funding Programme for Basic Research |
Start Date: | 03/2005 |
Abstract: |
Oxidation is one of the fundamental chemical reactions/processes in nature and much of modern organic and inorganic chemistry has been devoted to the development of new methods for the oxidation of organic compounds such as alkenes and sulfides. In this regard, processes that can perform this reaction efficiently in an asymmetric sense are highly valued. Yet more value is added if the process is environmentally friendly, since many such reactions use polluting metal catalysts or produce ecologically undesired by-products. The objective of this proposed project is to develop a novel approach to such non-polluting, asymmetric alkene and sulphide oxidation that uses only a chiral alcohol solvent or catalyst as the source of asymmetry and the only by-product of which is water. |

Abstract: |
We plan to develop a new type of electrochemiluminescent (ECL) chemosensor on the basis of quenching effects of the analytes on a novel emission route of the coreactant ECL system. Unlike the conventional luminescence quenching which is due to the electron or energy transfer between the luminophor excited state and the quencher species, the quenching effect used here results from the interception of the ECL intermediate radicals by the analyte molecules. Our recent experimental results revealed that the ECL signal of the [Ru(bpy)3]2+/TPrA system via the low-oxidation-potential (LOP) route is highly sensitive to the presence of reducible species, such as oxygen. In this proposal, detailed investigation of the novel ECL quenching effect will be conducted, and the possibility of utilizing this effect in reducible-species sensing will be explored, aiming at the development of a new type of ECL chemosensor.The key issues of this study are:1. To study the novel quenching effects of various reducible species on coreactant ECL systems. First, the study will focus on the [Ru(bpy)3]2+/TPrA system. It is generally accepted that the formation of the excited state is via the electron-transfer between [Ru(bpy)3]3+ and highly reducing TPrA free radical generated upon TPrA oxidation. The ECL signal could be quenched by species that is able to intercept the intermediate radical before it joins in the ECL reaction. Longer lifetime of the radical species and higher reaction rate of the radical with quenchers will lead to more efficient quenching. The literature studies of the ECL mechanism of the [Ru(bpy)3]2+/TPrA system have revealed three emission routes, i.e. catalytic route, direct coreactant oxidation route and LOP ECL route. The lifetime of the TPrA free radical may be different in each case. As indicated in our recent work of the oxygen effects on coreactant ECL, the quenching efficiency is much higher for the LOP ECL route as compared with those for the other two routes, suggesting the longer lifetime of TPrA free radical in the LOP ECL process. Therefore, the LOP ECL of the [Ru(bpy)3]2+/TPrA system is expected to be an ideal emission signal sensitive to reducible species in solution. The quenching effects of various reducible species (such as oxygen, metal cations, benzoquinone, et al) on the LOP ECL signal will be investigated.The recent study of the PI’s group has revealed that a strong and reproducible LOP ECL signal of the [Ru(bpy)3]2+/TPrA system can be obtained at a nonionic fluorosurfactant (FSN)-modified gold electrode. This makes it feasible to employ the LOP ECL signal in quantitative analysis. Secondly, we will explore the quenching effects on the coreactant ECL systems other than [Ru(bpy)3]2+/TPrA. For example, other trialkylamines (such as triethylamine and trimethylamine) and some organic acid (such as oxalate) can also be employed as ECL coreactants. The quenching behavior of these systems will be examined and compared with that of the [Ru(bpy)3]2+/TPrA system. This study may lead to a better understanding of the novel quenching process. 2. To develop a new type of ECL chemosensor based on the quenching effect of the analyte on LOP ECL signal.On the basis of the above studies, we will develop practical chemosensors for some analytes of interest using a flow-injection system coupled by an ECL detector. The auto-controllable flow-injection system will be established to achieve good reproducibility of the ECL measurement. Since the modification of the gold electrode with nonionic fluorosurfactant molecules is based on the physical adsorption, it is feasible to clean and modify the electrode in situ. If a microelectrode array is used for the ECL detection, the whole sensor system may be minimized, and a chip-based analytical method may be achieved. |
