Discovery And Characterization Of Small Molecule Inhibitors Of Bromodomains, Md Rezaul Karim

USF Tampa Graduate Theses and Dissertations

The epigenetic “reader” modules bromodomains (BRDs) exert their diverse cellular functions through the recognition of acetylated lysines on histones and other proteins. Small molecule inhibitors of bromodomains have emerged as a promising therapeutic strategy to treat atherosclerotic cardiovascular diseases and cancers. Therefore, a large number of small molecule bromodomain inhibitors have been developed in the last decade, some of which are currently being assessed in the clinic. However, the success of bromodomain inhibitors is currently limited to the bromodomain and extra-terminal domain (BET) subfamily.

To address these, bromodomains outside the BET subfamily (non-BETs) such as TAF1, BRD7/9, TRIM28, and BRD8 …

Structure Based Drug Design Targeting Bacterial Antibiotic Resistance And Alzheimer's Disease, Eric Michael Lewandowski

USF Tampa Graduate Theses and Dissertations

Structure based drug design is a rapidly advancing discipline that examines how protein targets structurally interact with small molecules, or known inhibitors, and then uses this information to lead inhibitor optimization efforts. In the case of novel inhibitors, protein structural information is first obtained via X-ray crystallography, NMR studies, or a combination of both approaches. Then, computational molecular docking is often used to screen, in silico, millions of small molecules and calculate the potential interactions they may have with the target protein’s binding pocket, in hopes of identifying novel low affinity inhibitors. By examining the interactions these small, low affinity, …
