Inhibition of the HIV-1 nuclear regulatory protein tat could potentially yield particularly useful drugs because it functions as an activator of transcription. It has no known cellular counterpart, and deletions in the tat gene destroy the ability of HIV-1 to replicate. We recently reported that a structurally unique class of tat inhibitors, 3-keto/enol 4,5-alpha-epoxy steroids bearing electron-withdrawing
抑制HIV-1核调节蛋白tat可能会产生特别有用的药物,因为它起着转录激活剂的作用。它没有已知的细胞对应物,并且tat基因的缺失破坏了HIV-1复制的能力。我们最近报道,在结构上独特的一类tat抑制剂,在位置2带有吸电子取代基的3-酮/烯醇4,5-α-环氧类固醇,在无病毒转染的SW480细胞中特异性抑制tat诱导的基因表达。在本文中,我们报告了类固醇系列的其他SAR(结构-活性关系)和药效团定位于A环功能的情况。对天然类固醇立体化学的对映选择性偏弱,并且在吸电子基团中存在额外的SAR提示。
