(Cp-THF)-derived HIV-1 protease inhibitors are described. Various C3-functional groups on the Cp-THF ligand were investigated in order to maximize the ligand-binding site interactions in the flap region of the protease. Inhibitors 3c and 3d have displayed the most potent enzyme inhibitory and antiviral activity. Both inhibitors have maintained impressive activity against a panel of multidrug resistant HIV-1 variants
描述了新型 C3 取代的环戊基四氢呋喃 (Cp-THF) 衍生的 HIV-1 蛋白酶抑制剂的设计、合成和生物学评价。研究了 Cp-THF 配体上的各种 C3 官能团,以最大限度地提高蛋白酶瓣区中的配体结合位点相互作用。抑制剂3c和3d显示出最有效的酶抑制和抗病毒活性。两种抑制剂都对一组多药耐药 HIV-1 变体保持了令人印象深刻的活性。3c结合的 HIV-1 蛋白酶的高分辨率 X 射线晶体结构揭示了对配体结合位点相互作用的许多重要分子见解。
