Abstract:

Numerous enzymatic reactions are controlled by the chemistry of metallic ions. This dissertation investigates the electronic properties of three transition metal (copper, chromium, and nickel) complexes and describes modeling studies performed on glutathione synthetase. (1) Copper nitrene complexes were computationally characterized, as these complexes have yet to be experimentally isolated. (2) Multireference calculations were carried out on a symmetric C2v chromium dimer derived from the crystal structure of the [(tBu3SiO)Cr(µ-OSitBu3)]2 complex.

Abstract:

A range of fluorescein derivatives were synthesised via Pd0-mediated cross-coupling chemistry of the mono triflate of fluorescein with a variety of boronic acids and the optical properties of each dye was studied. Among these derivatives, a new multicolour pH–dependant anthofluorescein which was highly sensitive to pH changes and viscosity changes was identified. Work was carried out to explore intracellular catalysis based on the immobilisation of Pd0 nanoparticles on microspheres. The entrapped Pd0 nanoparticles were rapidly taken up by cells, stay harmlessly within the cytoplasm for days an

Abstract:

The formation of DNA triple helices offers the possibility of selectively targeting specific genes to control their expression in vivo. This anti-gene strategy provides powerful tools for the development of therapeutics (anti-cancer drugs, drugs for viral infections) at the transcriptional level. DNA triplexes are formed when an oligonucleotide binds to the major groove of double helical DNA; the third strand can bind in either a parallel motif, or an anti-parallel motif. The requirement of low pH for the protonation of cytosine in the parallel binding motif makes the formation of triple helic

Abstract:

The avalanche of data that followed the sequencing of the human genome has revealed an overwhelming biological complexity. No simple molecular explanation exists for most of the diseases and, in consequence, simple therapies have low probability of success. The emerging field of systems pharmacology seeks drugs of broad impact on molecular networks. To achieve so, it is necessary to integrate heterogeneous data, at different levels of complexity, and find correlations between them. This translational exercise is, perhaps, the major concern of current biomedical research. In this Thesis we und

Abstract:

Effective therapies typically target diseased tissues without significantly affecting healthy tissues. A tumor-related glycosphingolipid (GSL), such as ganglioside GD2, distinguishes neuroectoderm tumors from their healthy counterparts and is a validated tumor target. GD2 is clinically targeted for diagnosis and immunotherapy. GD2 plays an important functional role in tumor progression and in chemoresistance. It also plays an important functional role in pain; however, the mechanisms that make GD2 important in such phenomena remain unknown.Thus, understanding the structure-activity relationshi

New strategies for the high-throughput determination of protease substrate specificity using a dual colour microarray based format with a small library of FRET-based peptides were developed. Integral to this process was the development of an in-house hydrophobic microarray platform and the application of microarrays of microwells. Overall this allowed the rapid and quantitative analysis of a range of peptides with three proteases, subtilisin, chymopapain and thermolysin. An immobilised tetrafluoroarylsulfonyl chloride linker was developed to be used as a traceless linker for microwave-assisted

Abstract:

Triazabutadienes are nitrogen containing compounds with interesting acid-responsive behavior. These compounds are relatively stable, but once activated by an electrophile, for example through protonation, fall apart to yield diazonium and imine compounds. In general, diazonium compounds are unstable and require harsh methods of synthesis. Therefore, the use of triazabutadiene compounds as precursors to diazonium compounds, allows for a mild and more controlled access to this reactive moiety. This opens up diazonium chemistry to more complex chemical biology applications, as well as in the deve

Droplet-based microfluidic systems have recently been developed to overcome the problems of slow mixing and dispersion associated with traditional microfluidic systems. By utilising flow instabilities between two immiscible phases, droplets can be generated using normal microfluidic formats. Further, aqueous solutions can be confined and mixed within droplets, resulting in rapid homogenisation and no dispersion. Accordingly, droplet-based microfluidic systems have been utilised in various applications in a high-throughput manner. However, the techniques and methods for droplet formation, manip

Because of this limited knowledge, this dissertation set out to examine the affect of salinity on Cu toxicity and accumulation across salinities from FW to sea water (SW). First, this work examined

However, those syntheses can result in retention of the starting oxides in the reaction products, leading to difficulties in analysis of the magnetic properties.

The terminal alkyne is one of the most widely used chemical moieties in chemical biology. Thanks to the relative absence of this functional group in biology, it has become a widespread functional handle for a plethora of biorthogonal chemistries. Our group has extended the scope of this functionality by developing a biological variant of the Glaser-Hay coupling, which brings together two terminal alkynes to form a diyne linkage. However, our initial findings revealed that the chemistry is plagued by protein degradation due to a deleterious copper(II) hydroxyl intermediate. Herein we extend the

Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>Proteins perform myriad functions inside cells. In vitro studies of purified proteins yield important information about their function, but it is an important pursuit in cell biology to study proteins within the native context of intact cells, since their physiological functions might not be recapitulated in any other environment. The most basic question, the location of a protein within the cell, is difficult to answer,

Abstract:

Mathematical modeling has been instrumental to the development of natural sciences over the last half-century. Through iterated interactions between modeling and real-world exper- imentation, these models have furthered our understanding of the processes in biology and chemistry that they seek to represent. In certain application domains, such as the field of car- diac biology, communities of modelers with common interests have emerged, leading to the development of many models that attempt to explain the same or similar phenomena. As these communities have developed, however, reporting standa

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemistry, 2008.<br>Vita.<br>Includes bibliographical references.<br>This thesis employs colloidal semiconductor nanocrystals (NCs) as nanoscale emissive probes to investigate the physics of light emitting diodes (LEDs), as well as to unveil properties of cells that conventional imaging techniques cannot reveal. On the LED side, in particular, Chapter 2 utilizes individual NCs to alter layered organic LED structures at nanometer scale, resulting in spectrally resolved electroluminescence from single colloidal CdSe/ZnS (core/shell

Abstract:

Type 2 phosphatidylinositol-5-phosphate 4-kinase (PI5P4K) converts phosphatidylinositol-5-phosphate to phosphatidylinositol-4,5-bisphosphate. Mammals have three genes, PIP4K2A, PIP4K2B and PIP4K2C that encode the enzymes PI5P4Kα, PI5P4Kβ and PI5P4Kγ respectively. Studies in mice showed that PI5P4Kβ is a negative regulator of insulin signaling (Lamia et al., 2004) and that co-deletion of Pip4k2b and Trp53 resulted in synthetic embryonic lethality (Emerling et al., 2013). Also, deletion of two alleles of Pip4k2a and one allele of Pip4k2b suppressed the appearance of tumors in Trp53-/- mice. Thes
