Substitution of the t-butylcarboxamide substituent in analogues of the HIV protease inhibitor (PI) Indinavir with a trifluoroethylamide moiety confers greater potency against both the wild-type (NL4-3) virus and PI-resistant HIV. The trifluoroethyl substituent also affords a slower clearance rate in vivo (dogs); however, this may be due to more potent inhibition of at least two P450 isoforms.
用三氟乙基酰胺部分取代HIV蛋白酶抑制剂(PI)茚地那韦的类似物中的叔丁基甲酰胺取代基可赋予针对野生型(NL4-3)病毒和PI抗性HIV的更大效力。三氟乙基取代基在体内的清除速度也较慢(狗)。但是,这可能是由于更有效地抑制了至少两种P450亚型。
