Nineteen new halogenated diarylpyridinamine (DAPA) analogues modified at the phenoxy C-ring were synthesized and evaluated for anti-HIV activity and certain drug-like properties. Ten compounds showed high anti-HIV activity (EC50 <10 nM). In particular, (E)-6-(2''-bromo-4''-cyanovinyl-6''-methoxy)phenoxy-N(2) -(4'-cyanophenyl)pyridin-2,3-diamine (8 c) displayed low-nanomolar antiviral potency (3-7 nM) against wild-type and drug-resistant viral strains bearing the E138K or K101E mutations, which are associated with resistance to rilvipirine (1 b). Compound 8 c exhibited much lower resistance fold changes (RFC: 1.1-2.1) than 1 b (RFC: 11.8-13.0). Compound 8 c also exhibited better metabolic stability (in vitro half-life) than 1 b in human liver microsomes, possessed low lipophilicity (clog D: 3.29; measured log P: 3.31), and had desirable lipophilic efficiency indices (LE>0.3, LLE>5, LELP<10). With balanced potency and drug-like properties, 8 c merits further development as an anti-HIV drug candidate.
合成了19种在苯氧基C环上修饰的新型卤代二芳基吡啶胺(DAPA)类似物,并对其抗HIV活性和某些类药性质进行了评估。10种化合物表现出高抗HIV活性(EC50<10 nM)。特别地,(E)-6-(2''-溴-4''-氰基乙烯基-6''-甲氧基)苯氧基-N(2) -(4'-氰基苯基)吡啶-2,3-二胺(8 c)对携带E138K或K101E突变的野生型和耐药病毒株显示出低纳摩尔抗病毒效力(3-7 nM),这些突变与对利匹韦林(1 b)的耐药性有关。化合物8 c的耐药倍数变化(RFC:1.1-2.1)远低于1 b(RFC:11.8-13.0)。在人肝微粒体中,化合物8 c还表现出比1 b更好的代谢稳定性(体外半衰期),具有低亲脂性(clog D:3.29;实测log P:3.31),并具有理想的亲脂效率指数(LE>0.3, LLE>5, LELP<10)。由于具有平衡的效力和类药性质,8 c作为抗HIV药物候选物值得进一步开发。
