GS-9148 (2'-Fd4AP, 4) has been identified as a nucleoside phosphonate reverse transcriptase (RT) inhibitor with activity against wild-type HIV (EC(50)=12 microM). Unlike many clinical RT inhibitors, relevant reverse transcriptase mutants (M184V, K65R, 6-TAMs) maintain a susceptibility to 2'-Fd4AP that is similar to wild-type virus. The 2'-fluorine group was rationally designed into the molecule to
GS-9148(2'-Fd4AP,4)已被鉴定为具有抗野生型HIV(EC(50)= 12 microM)活性的核苷膦酸酯逆转录酶(RT)抑制剂。与许多临床RT抑制剂不同,相关的逆转录酶突变体(M184V,K65R,6-TAMs)对2'-Fd4AP的敏感性与野生型病毒相似。将2'-氟基团合理地设计到分子中以改善选择性,在使用HepG2细胞的初步研究中,化合物4对线粒体DNA含量没有可测量的影响,表明线粒体毒性的可能性很低。
