Bruton's tyrosine kinase (BTK), a cytoplasmic tyrosine kinase, plays a central role in immunity and is considered an attractive target for treating autoimmune diseases. The use of currently marketed covalent BTK inhibitors is limited to oncology indications based on their suboptimal kinase selectivity. We describe the discovery and preclinical profile of LOU064 (remibrutinib, 25), a potent, highly
Bruton的酪氨酸激酶(BTK)是一种细胞质酪氨酸激酶,在免疫中起着核心作用,被认为是治疗自身免疫性疾病的诱人靶标。基于其次优激酶选择性,目前市售的共价BTK抑制剂的使用仅限于肿瘤适应症。我们描述了一种有效的,高度选择性的共价BTK抑制剂LOU064(remibrutinib,25)的发现和临床前概况。LOU064由于与BTK的非活性构象结合而表现出出色的激酶选择性,并且具有治疗自身免疫性疾病的同类最佳共价BTK抑制剂的潜力。它在大鼠胶原蛋白诱发的关节炎中表现出有效的体内靶标占有率,EC90为1.6 mg / kg,且剂量依赖性。
