Progress Toward the Total Synthesis of Vinigrol and Hibarimicin B
Vinigrol is a structurally unique diterpenoid natural product featuring a tricyclo[22.214.171.124.4a,8a]tetradecene carbon skeleton containing eight contiguous stereocenters and a challenging oxygenation pattern. Vinigrol has ...
Multi-Electron Reduction of Small Molecules by Triiron Reaction Sites
The observation that multi-electron activation of small molecule substrates occurs at polynuclear reaction sites, common to both metalloenzymes and heterogeneous catalysts, has led to the articulation of the polynuclear ...
Design and synthesis of dynamically assembling DNA nanostructures
Kinetically controlled isothermal growth is fundamental to biological development, but it remains challenging to rationally design molecular systems that self-assemble isothermally into complex geometries via prescribed ...
I. Targeted β-catenin Ubiquitination and Degradation Using Bifunctional Stapled Peptides II. Studies on Cell Penetration by Stapled Peptides
Hydrocarbon-stapled alpha-helical peptides represent a relatively new class of synthetic peptidomimetics capable of inhibiting protein-protein interactions. It has been shown that hydrocarbon "staples" spanning one or two ...
Trapping and Manipulating Single Molecules of DNA
This thesis presents the development and application of nanoscale techniques to trap and
The Role of Catalyst-Catalyst Interactions in Asymmetric Catalysis with (salen)Co(III) Complexes and H-Bond Donors
In asymmetric catalysis, interactions between multiple molecules of catalyst can be important for achieving high catalyst activity and stereoselectivity. In Chapter 1 of this thesis, we introduce catalyst-catalyst interactions ...
Synthesis, Structure, and Reactivity of New Palladium(III) Complexes
Palladium is one of the most common and versatile transition metals used in modern organometallic chemistry. The chemistry of palladium in its 0, +II, and +IV oxidation states is well-known; by comparison, the chemistry ...
Detection of Single-Molecule Optical Absorption at Room Temperature and Mechanistic Study of Transcriptional Bursting
Advances in optical imaging techniques have allowed quantitative studies of many biological systems. This dissertation elaborates on our efforts in both developing novel imaging modalities based on detection of optical ...
Small-molecule probes to explore cancer
Small molecules play important roles in therapeutics and drug discovery. Significant progress has been made by the chemical biology community to discover small-molecule probes to explore biological processes and to treat ...
Biomimetics through nanoelectronics: development of three-dimensional macroporous nanoelectronics for building smart materials, cyborg tissues and injectable biomedical electronics.
Nanoscale materials enable unique opportunities at the interface between physical and life sciences. The interface between nanoelectronic devices and biological systems makes possible communication between these two diverse ...
