A series of (E)-N-phenylstyryl-N-alkylacetamides, 5, were synthesized by direct reduction-acetylation of β-arylnitroolefins, followed by N-alkylation. The title compounds were characterized by 1H-NMR, EIMS and IR analysis. All the synthesized compounds were assayed as HIV-1 non-nucleoside reverse transcriptase inhibitors. A SAR study revealed that when group R1 in 5 was ortho-substituted, the resulting compounds showed better inhibitory activities against HIV-1 RT. Among the tested compounds, 5i (R1 = 2-Br, R2 = 3,5-difluorobenzyl) exhibited the highest enzyme activity, with a 88.89% inhibitory ratio against HIV-1 reverse transcriptase at the tested concentration. Further cell-based anti-HIV-1 assays showed that compound 5i exhibited a SI value of 29 with an EC50 value of 4 μM in C8166 cells.
通过对 β-芳基硝基烯烃进行直接还原-乙酰化,然后再进行 N-烷基化反应,合成了一系列 (E)-N- 苯乙烯-N-烷基乙酰胺 5。通过 1H-NMR、EIMS 和 IR 分析对标题化合物进行了表征。所有合成的化合物都被检测为 HIV-1 非核苷类逆转录酶抑制剂。SAR 研究表明,当 5 中的 R1 基团被正交取代时,所合成的化合物对 HIV-1 RT 具有更好的抑制活性。在测试的化合物中,5i(R1 = 2-Br,R2 = 3,5-二氟苄)的酶活性最高,在测试浓度下对 HIV-1 逆转录酶的抑制率为 88.89%。进一步的细胞抗 HIV-1 试验表明,化合物 5i 在 C8166 细胞中的 SI 值为 29,EC50 值为 4 μM。
