transition‐state models such as hydroxyethylamine (HEA) have been designed. We therefore pursued an efficient synthesis of an HEA isostere; this was performed with a novel one‐pot reduction–transimination–reduction reaction sequence as a key step. α‐Aminophosphonate and phosphoramidate derivatives of the HEA isostere were designed and synthesized, and all of the synthesized derivatives were assayed for their
HIV蛋白酶是用于AIDS治疗的有希望的药物靶标,迄今为止,已经报道了几种有效的HIV-1蛋白酶抑制剂。尽管现有的抑制剂显示出高选择性,但它们也与严重的副作用和可能出现的治疗耐药性有关。当HIV蛋白酶通过四面体中间体切割肽键时,已设计了各种过渡态模型,例如羟乙胺(HEA)。因此,我们追求了HEA等位基因的有效合成。这是通过新颖的一锅还原-转氨-还原反应序列作为关键步骤进行的。设计并合成了HEA等位基因的α-氨基膦酸酯和氨基磷酸酯衍生物,并测定了所有合成的衍生物对野生型和突变型HIV菌株的抗HIV活性。发现15 a是所有合成的化合物中针对III B和RES056菌株最具活性的化合物。由于已知膦酸酯具有生理稳定性,良好的细胞通透性和其他有希望的药代动力学特征,因此我们新合成的化合物具有替代现有治疗方法和诊断方法的潜力。
