an acceptable pharmacokinetic profile. Compound 4t has excellent potency against the HCV 1b replicon, with an EC50 = 2 nM and a selectivity index of >5000 with respect to cellular GAPDH. Compound 4t has an overall favorable pharmacokinetic profile with oral bioavailability values of 62%, 78%, and 18% in rats, dogs, and monkeys, respectively, as well as favorable tissue distribution properties with a
一种新型的,靶向NS4B丙型肝炎RNA复制的强效,和口服生物抑制剂,化合物4吨(PTC725),已经通过6-(吲哚-2-基)的化学优化吡啶-3-磺酰胺标识2,以改善DMPK和安全特性。SAR研究的重点是确定吲哚N-1,C-5和C-6位置的取代基与磺酰胺基的最佳组合,以限制体内氧化代谢的潜力并达到可接受的药代动力学轮廓。化合物4t具有抗HCV 1b复制子的出色效能,相对于细胞GAPDH ,EC 50 = 2 nM,选择性指数> 5000。复合4t 具有总体良好的药代动力学特征,大鼠,狗和猴子的口服生物利用度分别为62%,78%和18%,并且大鼠的肝血浆接触比为25,具有良好的组织分布特性。
