The Design, Synthesis and Optimization of Allosteric Hiv-1
THE DESIGN, SYNTHESIS AND OPTIMIZATION OF ALLOSTERIC HIV-1 INTEGRASE INHIBITORS DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Janet Antwi Graduate Program in Pharmaceutical Sciences The Ohio State University 2017 Dissertation Committee: Professor James R. Fuchs, Advisor Professor Werner Tjarks Professor Karl A. Werbovetz Copyright by Janet Antwi 2017 Abstract In the past quarter century, there has been tremendous progress in the discovery of antiretroviral therapy, making HIV/AIDS a manageable chronic disease. However, the HIV virus is relentless and continues to evolve under drug pressure to escape control and continue infection. The enzyme HIV integrase is responsible for the incorporation of viral double stranded DNA into a host chromosomal DNA and has recently become an attractive target in combating HIV resistance. Raltegravir (RAL), elvitegravir (EVG) and dolutegravir (DTG) are three clinically approved active-site integrase inhibitors. Unfortunately, mutations of the enzyme observed in patients have resulted in resistance to thedrug in the clinic. A new approach to targeting integrase (IN) is the development of allosteric inhibitors that specifically target the protein-protein interaction between IN and its cellular cofactor LEDGF/p75. Recently discovered quinoline-based allosteric integrase inhibitor (ALLINI) B1224436 was the first compound to advance into clinical trials but was discontinued due to poor pharmacokinetic properties including low in vivo clearance. In addition, several reports have revealed the emergence of resistance due to mutation to quinoline based ALLINIs. Applying scaffold hopping approach, several pyridine-based, thiophenes, ii pyrazoles, isoquinolines and other heteroaromatic cores have been studied as ALLINIs. -
