A series of 4-nitroimidazole derivatives bearing substituted piperazines (5, 8, 9, 12, 14, 16, 17, and 19 - 21) were synthesized with the aim to develop new non-nucleoside reverse transcriptase inhibitors (NNRTIs). The newly synthesized compounds were assayed against HIV-1 and HIV-2 in MT-4 cells. All compounds are inactive, except compound 21 which showed inhibition of HIV-1 with EC50 0.20 μg/mL, and therapeutic indexes (SI) of 12.
一系列携带取代哌嗪的4-硝基咪唑衍生物(5、8、9、12、14、16、17和19-21)被合成,旨在开发新的非核苷类逆转录酶抑制剂(NNRTIs)。新合成的化合物在MT-4细胞中对HIV-1和HIV-2进行了检测。所有化合物均无活性,除了化合物21显示对HIV-1的抑制,EC50为0.20 μg/mL,疗效指数(SI)为12。
