inflammatory diseases. Medicinal chemistry optimization of high throughput screening (HTS) hits with the help of structure based drug design led to the identification of orally-bioavailable quinazoline based IRAK4 inhibitors with excellent pharmacokinetic profile and kinase selectivity. These highly selective IRAK4 compounds show activity in vivo via oral dosing in a TLR7 driven model of inflammation.
IL-1R和TLR基信号转导涉及白介素1受体相关激酶4(IRAK4)。因此,对该蛋白激酶活性的选择性抑制代表了炎性疾病治疗的有吸引力的靶标。借助基于结构的药物设计,高通量筛选(HTS)命中的药物化学优化导致鉴定出具有出色药代动力学特征和激酶选择性的口服生物利用喹唑啉类IRAK4抑制剂。这些高选择性IRAK4化合物在TLR7驱动的炎症模型中通过口服给药具有体内活性。
