manuscript reports an identification of a highly potent, orally bioavailable hepatitis C virus entry inhibitor through optimization of a previously reported class of molecules (1) that were not stable in the rat plasma. Compound 39 (ITX 4520) exhibited an excellent PK profile in both rats and dogs with good oral exposure, half-life and oral bioavailability. The compound is also well-tolerated in the preliminary
该手稿报告了通过优化先前报道的在大鼠血浆中不稳定的一类分子(1)的鉴定,确定了一种高效,口服可生物利用的丙型肝炎病毒进入抑制剂。化合物39(ITX 4520)在大鼠和狗中均表现出出色的PK曲线,具有良好的口服暴露,半衰期和口服生物利用度。该化合物在初步的体内毒性研究中也具有良好的耐受性,并已被选为我们的HCV临床管线的临床前候选药物。
