irreversible BTK inhibitor. In vitro, 14b showed IC50 of 1.0 nM and 0.8 nM, in BTK and TMD8 assays, respectively. In vivo, 14b displayed robust efficacy in collagen-induced arthritis (CIA) and TMD8 xenograft models, which could be correlated with its improved oral bioavailability. In the repeated dose acute toxicity study, 14b showed no adverse changes, indicating that the BTK inhibitor 14b could be viable
为了发现一流的布鲁顿酪氨酸激酶 (BTK) 抑制剂,用于治疗癌症(B 细胞淋巴瘤 (BCL))和类风湿性关节炎 (RA) 等自身免疫性疾病,在本研究中,进行了新的结构优化出去。引入新型双环胺接头和芳族主链导致了一系列化合物9a-h和14a-u。发现化合物14b是有效的、口服生物可利用的、选择性的和不可逆的 BTK 抑制剂。在体外,14b在 BTK 和 TMD8 测定中分别显示 IC 50为 1.0 nM 和 0.8 nM。体内, 14b在胶原蛋白诱导的关节炎 (CIA) 和 TMD8 异种移植模型中显示出强大的功效,这可能与其改善的口服生物利用度相关。在重复剂量急性毒性研究中,14b没有显示出不良变化,表明 BTK 抑制剂14b可能是治疗自身免疫性疾病的可行治疗选择。
