series of potent dual JAK1/3 inhibitors have been developed from a moderately selective JAK3 inhibitor. Substitution at the C6 position of the pyrrolopyridazine core with aryl groups provided exceptional biochemical potency against JAK1 and JAK3 while maintaining good selectivity against JAK2 and Tyk2. Translation to in vivo efficacy was observed in a murine model of chronic inflammation. X-ray co-crystal
从中等选择性的JAK3抑制剂已经开发出一系列有效的双重JAK1 / 3抑制剂。在吡咯并哒嗪核心的C6位置被芳基取代可提供对JAK1和JAK3的出色生化效能,同时保持对JAK2和Tyk2的良好选择性。在慢性炎症的鼠模型中观察到体内功效的转化。X射线共晶体结构测定证实了JAK3中推测的抑制剂结合方向。将描述减少hERG通道抑制的努力。
