value of 0.058 μM and a therapeutic index (TI) of 1000. The activity of 9 was better than that of 4-methyl DCK (2, EC50: 0.126 μM, TI: 301.2) in the same assay. Additionally, 9 also showed antiviral activity against a multi-RT inhibitor-resistant strain (RTMDR), which is insensitive to most DCK analogs. Compared with 2, compound 9 has a less complex structure, fewer hydrogen-bond acceptors, and a reduced
十三新颖开环DCK类似物(4 - 16)配有几个新的骨架设计,合成和筛选的体外抗HIV-1活性。其中,三种化合物(5,13,和16)显示出中度的活性,和化合物9显示出与
EC的最佳活性50 0.058μM的值和治疗指数的1000(TI)的活性9明显优于4-甲基 DCK ( 2 ,
EC 50 : 0.126 μM, TI: 301.2) 在相同的测定中。此外,9还对多 RT
抑制剂耐药菌株 (RTMDR) 显示出抗病毒活性,该菌株对大多数 DCK 类似物不敏感。与2相比,化合物9的结构更简单,氢键受体更少,log P值降低 。因此,它可能表现出更好的 A
DME,并且似乎是作为抗 HIV 候选物进一步开发的有希望的新线索。
