FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedRecently, we disclosed a new class of HCV polymerase inhibitors discovered through high-throughput screening (HTS) of the GlaxoSmithKline proprietary compound collection. This interesting class of 3-(1,1-dioxo-2H-1,2,4-benzothiadiazin-3-yl)-4-hydroxy-2(1H)-quinolinones potently inhibits HCV polymerase enzymatic activity and inhibits the ability of the subgenomic HCV replicon to replicate in Huh-7 cells. This report will focus on the structure-activity relationships (SAR) of substituents on the quinolinone ring, culminating in the discovery of 1-(2-cyclopropylethyl)-3-(1,1-dioxo-2H-1,2,4-benzothiadiazin-3-yl)-6-fluor o-4-hydroxy-2(1H)-quinolinone (130), an inhibitor with excellent potency in biochemical and cellular assays possessing attractive molecular properties for advancement as a clinical candidate. The potential for development and safety assessment profile of compound 130 will also be discussed. 3-(1,1-dioxo-2H-(1,2,4)-benzothiadiazin-3-yl)-4-hydroxy-2(1H)-quinolinones , potent inhibitors of hepatitis C virus RNA-dependent RNA polymerase.,Tedesco R, Shaw AN, Bambal R, Chai D, Concha NO, Darcy MG, Dhanak D, Fitch DM, Gates A, Gerhardt WG, Halegoua DL, Han C, Hofmann GA, Johnston VK, Kaura AC, Liu N, Keenan RM, Lin-Goerke J, Sarisky RT, Wiggall KJ, Zimmerman MN, Duffy KJ J Med Chem. 2006 Feb 9;49(3):971-83.
