A3G-dependent Vif degradation. Replacement of amide functionality in RN-18 (IC50 = 6 μM) by isosteric heterocycles resulted in the discovery of a 1,2,3-trizole, 1d (IC50 = 1.2 μM). We identified several potent HIV-1 inhibitors from a 1d based library including 5ax (IC50 = 0.01 μM), 5bx (0.2 μM), 2ey (0.4 μM), 5ey (0.6 μM), and 6bx (0.2 μM).
Vif拮抗剂是基于RN-18的病毒感染因子(Vif),可通过拯救APOBEC3G(A3G)表达并增强A3G依赖性Vif降解来降低病毒感染性。用等位杂环取代RN-18中的酰胺官能团(IC 50 = 6μM)导致发现1,2,3-三唑,1d(IC 50 = 1.2μM)。我们从基于1d的文库中鉴定了几种有效的HIV-1抑制剂,包括5ax(IC 50 = 0.01μM),5bx(0.2μM),2ey(0.4μM),5ey(0.6μM)和6bx(0.2μM)。
