Item A Novel Synthesis of Functionalized Oxazolidine-2,4-diones(2017-10-12) Duddupudi, Anantha; Vo, HienOxazolidinedione analogs have been found to be potent and selective Mineralocorticoid Receptor (MR) antagonists. The natural endogenous hormone Aldosterone activates MR leading to chronic kidney disease, hypertension and congestive heart failure via electrolyte imbalance.There is a significant need for the synthesis of Oxazolidinediones and related compounds. This motivated us to develop of a method for the synthesis of functionalized Oxazolidinediones that could be used in the preparation of pharmacologically active compounds.Item A Partial Statistical Model of the Green Fluorescent Protein(2018-10-18) Vo, HienSince its discovery, the green fluorescent protein (GFP) and its variants have found many applications in biological research. Due to the fluorophore’s sensitivity to its environment, many of the protein’s fluorescence properties (brightness, color, sensitivity to pH, etc.) can be configured by mutating the surrounding residues. The major problem with introducing point mutations to the GFP is that the protein is highly sensitive to changes in the sequence. Here, we have developed a statistical model to learn which mutations should be introduced together in pairs. To do so, we trained a Potts model using evolutionary data for the GFP family and then performed Direct Coupling Analysis (DCA) to identify co-evolved pairs of residues. This project was completed with contributions from Lena Simine from Rice University.
