Abstract

A quinolizidine-type alkaloid aloperine was found to inhibit HIV-1 infection by blocking HIV-1 entry. Aloperine inhibited HIV-1 envelope-mediated cell-cell fusion at low micromolar concentrations. To further improve the antiviral potency, more than 30 aloperine derivatives with a variety of N12-substitutions were synthesized. Among them, 12d with an N-(1-butyl)-4-trifluoromethoxy-benzamide side chain showed the most potent anti-HIV-1 activity with EC50 at 0.69 μM. Aloperine derivatives inhibited both X4 and R5 HIV-1 Env-mediated cell-cell fusions. In addition, both BMS-806, a compound representing a class of HIV-1 gp120-targeting small molecules in clinical trials, and resistant and sensitive HIV-1 Env-mediated cell-cell fusions were equally sensitive to aloperine derivatives. These results suggest that aloperine and its derivatives are a new class of anti-HIV-1 entry inhibitors.

摘要

人们发现喹诺里西啶型生物碱阿洛哌丁通过阻断HIV-1进入来抑制HIV-1感染。阿洛哌丁在低微摩尔浓度下可抑制HIV-1包膜介导的细胞间融合。为进一步提高抗病毒效力,合成了30多种具有各种N12取代基的阿洛哌丁衍生物。其中,带有N-(1-丁基)-4-三氟甲氧基苯甲酰胺侧链的12d显示出最有效的抗HIV-1活性,其半数有效浓度(EC50)为0.69 μM。阿洛哌丁衍生物可抑制X4和R5 HIV-1包膜介导的细胞间融合。此外,在临床试验中代表一类靶向HIV-1 gp120的小分子化合物的BMS-806,以及耐药和敏感的HIV-1包膜介导的细胞间融合对阿洛哌丁衍生物同样敏感。这些结果表明,阿洛哌丁及其衍生物是一类新型的抗HIV-1进入抑制剂。
