that the virally encoded HIV protease is vital for propagation, inhibition of this enzyme has become a major target for AIDS chemotherapy. Consequently, numerous efforts aimed at the development of potent and selective inhibitors have been undertaken[2]. Based on the substrate transition state, we designed and synthesized a novel class of HIV protease inhibitors containing allophenylnorstatine [Apns;
开发用于治疗艾滋病的有效治疗剂仍然是一个具有挑战性的问题。由于发现病毒编码的 HIV 蛋白酶对繁殖至关重要,因此抑制这种酶已成为 AIDS 化疗的主要目标。因此,已经进行了许多旨在开发有效和选择性抑制剂的努力[2]。基于底物过渡态,我们设计并合成了一类含有别苯去甲司他汀的新型 HIV 蛋白酶抑制剂 [Apns; (2S, 3S) -3-amino-2-hydroxy-4-phenylbutyric acid] 与羟甲基羰基 (HMC) 等排体。其中,三肽 KNI-272 是一种高选择性和超强效的 HIV 蛋白酶抑制剂 (Ki = 5.5 pM) [3]。KNI-272 表现出有效的体外和体内抗病毒活性,且细胞毒性较低 [4]。核磁共振,
