3-Hydroxy-6,7-dihydropyrimido [2,1-c][1,4]oxazin-4(9H)-ones as new HIV-1 integrase inhibitors WO2011046873 A1

[摘要]：Since the discovery of raltegravir, the first FDA-approved integrase inhibitor, Merck and other pharmaceutical companies have continued their research programs in order to introduce novel molecules as second generation integrase inhibitors. Elvitegravir (Japan Tobacco/Gilead) and dolutegravir (Shionogi/GlaxoSmithKline) are in advanced stages of clinical development. Bristol-Myers Squibb has developed molecules leading to BMS-707035, which was stopped at the Phase II clinical trial stage. Herein is presented the last patent from this company where, in particular, new 3-hydroxy-6,7-dihydropyrimido[2,1-c][1,4] oxazin-4(9H)-ones are synthesized and their biological properties given.
