  Synthesis and anti-HIV activity of new alkenyldiarylmethane (ADAM) non-nucleoside reverse transcriptase inhibitors (NNRTIs) incorporating benzoxazolone and benzisoxazole rings

  摘要：

  The HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) constitute a large and structurally diverse set of compounds, several of which are currently used in the treatment of AIDS. A series of novel alkenyldiarylmethanes (ADAMs) were designed and synthesized as part of an ongoing investigation to replace the metabolically labile methyl ester moieties found in the ADAM pharmacophore with stable modifications that retain the potent anti-HIV activity of the parent compounds. Unsurprisingly, the rat plasma half-lives of the new ADAMs were not improved when compared to the parent compounds, but all of the synthesized ADAMs inhibited the cytopathic effect of HIV-1 in cell culture. The most potent compound identified was (E)-5-[1-(3,7-dimethyl-2oxo-2,3-dihydro-benzoxazol-5-yl)-5-methoxycarbonyl-pent-1-enyl]-2-methoxy-3-methylbenzoic acid methyl ester (7), which inhibited the cytopathic effects of both HIV-1(RF) and HIV-1(IIIB) strains in cell cultures with EC50 values of 30 and 90 nM, respectively, and inhibited HIV-1 reverse transcriptase with an IC50 of 20 nM.

  ‘best’ one in terms of inhibitory activity versus HIV-1 reverse transcriptase (RT) led to the realization that the potencies are critically dependent on the surrounding structure at each location, and therefore the definition of universal rank order is impossible. This investigation produced several new non-nucleoside reverse transcriptase inhibitors in which all three of the three methyl esters of the

  烯基二芳基甲烷（ADAM）是一类针对HIV-1的非核苷类逆转录酶抑制剂（NNRTIs）。四个化学和代谢稳定的ADAM结合了N先前已经报道了先导化合物的甲酯的-甲氧基亚氨基卤化物的替代物。在这项研究中，合成了二十五个新的ADAM，以研究在三个不同的位置安装九个不同的甲酯生物异构体的生物学后果。尝试定义甲基酯生物异构体的普遍等级顺序，并发现其抑制活性相对于HIV-1逆转录酶（RT）的“最佳”水平，这使人们认识到，效力在很大程度上取决于每个位置的周围结构，因此，不可能定义通用等级顺序。这项研究产生了几种新的非核苷类逆转录酶抑制剂，其中先导化合物的三个甲基酯中的所有三个都被甲基酯生物等排体取代，

  Non-nucleoside inhibitors of HIV reverse transcriptase (NNRTIs), albeit not the mainstays of HIV/AIDS treatment, have become increasingly important in highly active antiretroviral therapy (HAART) due to their unique mechanism of action. Several years ago our group identified the alkenyldiarylmethanes (ADAMs) as a potent and novel class of NNRTIs; however, the most active compounds were found to be

  HIV逆转录酶（NNRTIs）的非核苷抑制剂尽管不是HIV / AIDS治疗的主要手段，但由于其独特的作用机理，在高活性抗逆转录病毒疗法（HAART）中已变得越来越重要。几年前，我们的研究小组将烯基二芳基甲烷（ADAMs）鉴定为一种有效的新型NNRTIs。然而，发现活性最高的化合物在代谢上不稳定。随后的工作通过用各种杂环，腈和硫代酯代替不稳定的酯，从而合成了33种具有改善的代谢特性的类似物。结果，在纳摩尔浓度范围内鉴定出许多具有抗HIV活性的水解稳定的NNRTI。此外，基于新的ADAM系列，开发了一种改进的药效团模型，
