human immunodeficiency virus type 1 (HIV-1) nonnucleoside reverse transcriptase (RT) inhibitors (NNRTIs) whose prototype is 5. Molecular modeling studies based on the X-ray structures of HIV-1 RT prompted the synthesis of novel analogues which were tested as anti-HIV agents. The PBO derivatives specifically designed to target the highly conserved amino acid residues within the beta12-beta13 hairpin, namely
吡咯并苯并恶嗪酮(PBO)代表一类新型的人类免疫缺陷病毒1型(HIV-1)非核苷逆转录酶(RT)抑制剂(NNRTIs),其原型为5。合成了新的类似物,这些类似物已被测试为抗HIV药物。专为靶向β12-β13发夹内的高度保守的氨基酸残基(即引物抓地力)而专门设计的PBO衍生物被证明对最常见的突变酶(包括高度耐药的K103N突变株)非常有效。根据与RT结合位点可能的相互作用,讨论了结构活性关系(SAR),具体取决于C-6取代基的性质。在所研究的吡咯并苯并a庚因中,15c似乎是该系列中最有前途的NNRTI,其特征在于有效的抗病毒活性,广谱和低细胞毒性。15c显示了与AZT的协同抗病毒活性。
