and highly selective JNK3 inhibitors with neuroprotective activity and good oral bioavailability. One lead compound, A53, was a potent and selective JNK3 inhibitor (IC50 = 78 nM) that had significant inhibition (>80% at 1 μM) to only JNK3 in a 398-kinase panel. A53 had low inhibition against JNK3 and high stability (t1/2(α) = 0.98 h, t1/2(β) = 2.74 h) during oral administration. A modeling study of A53
indolin-2-(4-thiazolidinone) 支架先前被证明是一种新的 JNK3 抑制化学型。然而,由于未确认的构型和较差的理化性质,更多的体内应用受到限制。在这里,indolin-2-(4-thiazolidinone) 支架验证了绝对构型;优化了支架上的取代基。使用激酶活性测定法进行了广泛的结构活性关系 (SAR) 研究,从而产生具有神经保护活性和良好口服生物利用度的强效和高选择性 JNK3 抑制剂。一种先导化合物A53是一种有效的选择性 JNK3 抑制剂 (IC 50 = 78 nM),在 398 激酶组中仅对 JNK3 具有显着抑制作用(在 1 μM 时 >80%)。A53 在口服给药期间对 JNK3 具有低抑制和高稳定性(t 1/2(α) = 0.98 h,t 1/2(β) = 2.74 h)。对人 JNK3 中A53的建模研究表明,基于 indolin-2-(4-thiazolidinone)
