Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 57825-30-6, is researched, SMILESS is CCC1=CC=C(CBr)C=C1, Molecular C9H11BrJournal, Article, Research Support, N.I.H., Extramural, Research Support, U.S. Gov’t, Non-P.H.S., Journal of Medicinal Chemistry called Optimization of Potent and Selective Quinazolinediones: Inhibitors of Respiratory Syncytial Virus That Block RNA-Dependent RNA-Polymerase Complex Activity, Author is Matharu, Daljit S.; Flaherty, Daniel P.; Simpson, Denise S.; Schroeder, Chad E.; Chung, Donghoon; Yan, Dan; Noah, James W.; Jonsson, Colleen B.; White, E. Lucile; Aube, Jeffrey; Plemper, Richard K.; Severson, William E.; Golden, Jennifer E., the main research direction is quinazolinedione inhibitor respiration syncytial virus RNA polymerase.SDS of cas: 57825-30-6.
A quinazolinedione-derived screening hit 2 was discovered with cellular antiviral activity against respiratory syncytial virus (CPE EC50 = 2.1 μM), moderate efficacy in reducing viral progeny (4.2 log at 10 μM), and marginal cytotoxic liability (selectivity index, SI ∼ 24). Scaffold optimization delivered analogs with improved potency and selectivity profiles. Most notable were compounds 15 and 19 (EC50 = 300-500 nM, CC50 > 50 μM, SI > 100), which significantly reduced viral titer (>400,000-fold), and several analogs were shown to block the activity of the RNA-dependent RNA-polymerase complex of RSV.
