The present invention relates to a novel compound that has antiviral activity, in particular, inhibitory activity against the integrase of the human immunodeficiency virus (HIV).
The subject of this invention is a novel annelated 9-hydroxy-1,8-dioxo-1,3,4,8-tetrahydro-2H-pyrido[1,2-a]pyrazine-7-carboxamide of general formula 1 or 2, or any stereoisomer, any pharmaceutically acceptable salt, any solvate, or any crystalline or polycrystalline form thereof
wherein
ring A1 is an optionally methyl-substituted 5-7 membered saturated heterocycle or heterobicycle;
ring A2 is a 5-6 membered optionally methyl-substituted saturated or partially saturated monocyclic heterocycle;
ring A3 is a 5-6 membered monocyclic saturated cycloalkane or tetrahydro-2H-pyran;
R is a 5-7 membered optionally substituted with one, two, or three optionally identical substituents monocyclic or bicyclic heterocyclic radical comprising 1-4 heteroatoms selected from the series O, S, and N except (2S,5R,13aS)-8-hydroxy-7,9-dioxo-N-[3-(trifluoromethyl)-pyridin-2-yl]methyl}-2,3,4,5,7,9,13,13a-octahydro-2,5-methanopurido[1',2':4,5]pyrazino[2,1-b][1,3]oxazepine-10-carboxamide (formula A4) and (1R,4S,12aR)-N-[(3,5-difluoropyridin-2-yl)methyl]-7-hydroxy-6,8-dioxo-1,2,3,4,6,8,12,12a-octahydro-1,4-methanodipyrido[1,2-a:1',2'-d]pyrazine-9-carboxamide (formula A5).
本发明涉及一种新型化合物,该化合物具有抗病毒活性,特别是对人类免疫缺陷病毒(HIV)的整合酶具有抑制活性。
