There is still an urgent need to develop nonnucleoside reverse transcriptase (RT) inhibitors (NNRTI) with a high-genetic barrier to resistance that facilitate patient adherence and allow durable suppression of HIV-1 replication. In this study, we describe the synthesis of a novel series of N-aminoimidazole (NAIM) analogs. Each of the NAIM analogs display potent activity against wild-type recombinant purified HIV-1 RT as well as RTs containing the K103N or Y181C resistance mutations. The analogs, however, do not exhibit significant antiviral activity in cell culture and were, in general, cytotoxic. Nevertheless, these data suggest that the NAIM backbone may provide a suitable scaffold from which inhibitors active against NNRTI-resistant HIV-1 could be developed.
目前仍迫切需要开发具有高耐药遗传屏障的非核苷类逆转录酶抑制剂(NNRTI),以促进患者依从性并实现对 HIV-1 复制的持久抑制。在本研究中,我们描述了一系列新型 N-氨基咪唑(NAIM)类似物的合成。每个NAIM类似物均显示出对野生型重组纯化 HIV-1 逆转录酶以及含有 K103N 或 Y181C 耐药突变的逆转录酶的强大活性。然而,这些类似物在细胞培养中并未表现出明显的抗病毒活性,并且通常具有细胞毒性。尽管如此,这些数据表明 NAIM 骨架可能提供了一个合适的支架,从中可以开发出针对 NNRTI 耐药 HIV-1 的有效抑制剂。
