leading to the identification of 3 with characteristics that provided for targeted exposure and PK properties in three preclinical species. However, the physical properties of 3 limited plasma exposure at higher doses, both in preclinical studies and in clinical trials as the result of dissolution- and/or solubility-limited absorption, a deficiency addressed by the preparation of the phosphonooxymethyl prodrug
描述了从1开始递送替米沙韦(3,BMS-626529)的HIV-1附着抑制剂(AIs)的4-甲氧基-6-氮杂吲哚系列的优化。通过将N-连接的,sp 2-杂化的杂芳基环并入杂环核的7位,可获得最有效的药效和药代动力学(PK)性能提高。遵守共面性模型的化合物可提供靶向的抗病毒效力,从而鉴定出3种具有为三种临床前物种提供靶向暴露和PK特性的特征。但是3的物理性质在临床前研究和临床试验中,由于溶解和/或溶解度受限的吸收而限制了较高剂量的血浆暴露,这是膦酰氧甲基前药4(BMS-663068,fostemsavir)的制备所解决的缺陷。4的缓释制剂目前正处于III期临床试验中,已显示出有望在高度治疗经验丰富的HIV-1感染患者中作为药物联合疗法的一部分。
