A series of HIV protease inhibitors possessing a hydroxylaminepentanamide transition state isostere have been developed. Incorporation of a basic amine into the backbone of the L-685,434 (2) series provided antiviral potency combined with a highly improved pharmacokinetic profile in animal models. Guided by molecular modeling and an X-ray crystal structure of the inhibited enzyme complex, we were able
已经开发了一系列具有羟胺戊酰胺过渡态等排体的HIV蛋白酶抑制剂。将碱性胺掺入L-685,434(2)系列的骨架中可提供抗病毒效力,并在动物模型中具有高度改善的药代动力学特征。在分子模型和抑制的酶复合物的X射线晶体结构的指导下,我们能够设计L-735,524。该化合物有效且竞争性抑制HIV-1 PR和HIV-2 PR,Ki值分别为0.52和3.3 nM。它还以25-50 nM的浓度阻止了HIV-1IIIb感染的MT4淋巴样细胞的扩散。迄今为止,已经报道了许多HIV-PR抑制剂,但由于缺乏可接受的口服生物利用度,因此在人体中的研究很少。L-735,524在三种动物模型中具有口服生物利用度,
