Is to provide a novel compound having an anti-viral activity, particularly a HIV integrase inhibitory activity, and a pharmaceutical composition, particularly an anti-HIV agent.
(wherein
R1 is hydrogen or lower alkyl;
X is lower alkylene etc.;
R2 is optionally substituted aryl;
R3 is hydrogen, halogen, hydroxy, optionally substituted lower alkyl etc.;
R4 is hydrogen, optionally substituted lower alkyl, optionally substituted cycloalkyl, optionally substituted cycloalkyl lower alkyl, optionally substituted aryl, optionally substituted aryl lower alkyl, optionally substituted heterocyclic group, optionally substituted heterocyclic lower alkyl etc.;
A broken line indicates the presence or absence of a bond;
B1 and B2 are such that any one of them is CR20R21, and the other is NR22 and, in this case, there is no broken line.
When B2 is NR22, R4 and R22 may be connected together to form an optionally substituted heterocycle;
When B2 is CHR21, R4 and R21 may be connected together to form an optionally substituted heterocycle.
Alternatively, B1 and B2 are independently C, CR23 or N and, in this case, B1 and B2 may be taken together to form a heterocycle.
R20, R21, R22 and R23 are independently hydrogen, optionally substituted lower alkyl, optionally substituted cycloalkyl, optionally substituted cycloalkyl lower alkyl etc.)
提供一种具有抗病毒活性的新化合物,特别是具有HIV整合酶抑制活性的化合物,以及一种制药组合物,特别是一种抗HIV药物。(其中R1为氢或较低的烷基;X为较低的烷基等;R2为可选取代的芳基;R3为氢、卤素、羟基、可选取代的较低烷基等;R4为氢、可选取代的较低烷基、可选取代的环烷基、可选取代的环烷基较低烷基、可选取代的芳基、可选取代的芳基较低烷基、可选取代的杂环基、可选取代的杂环较低烷基等;破折线表示键的存在或不存在;B1和B2是这样的,其中任意一个是CR20R21,另一个是NR22,此时没有破折线。当B2为NR22时,R4和R22可以连接在一起形成可选取代的杂环;当B2为CHR21时,R4和R21可以连接在一起形成可选取代的杂环。或者,B1和B2独立地为C、CR23或N,此时B1和B2可以结合形成一个杂环。R20、R21、R22和R23独立地为氢、可选取代的较低烷基、可选取代的环烷基、可选取代的环烷基较低烷基等。)
