A series of 7H-pyrrolo[2,3-d]pyrimidine derivatives were designed and synthesized as reversible BTK inhibitors, and evaluated their kinase selectivity, anti-proliferation against the B-cell lymphoma cell lines (Ramos, Jeko-1) and cell line BTK enhanced (Daudi) in vitro. Among them, compound 28a exhibited the most excellent potency (IC50 = 3.0 nM against BTK enzyme, 8.52 μM, 11.10 μM and 7.04 μM against
设计并合成了一系列7 H-吡咯并[2,3- d ]嘧啶衍生物作为可逆的BTK抑制剂,并评估了它们的激酶选择性,对B细胞淋巴瘤细胞系(Ramos,Jeko-1)和体外增强BTK(Daudi)细胞系。其中,化合物28a表现出最优异的效价( 针对BTK酶的IC 50 = 3.0 nM,针对Ramos,Jeko-1和Daudi细胞的IC 50 = 3.0 nM,分别针对Ramos,Jeko-1和Daudi细胞的IC 50 = 3.0 nM),良好的激酶选择性和抑制的BTK Y223自效性。磷酸化和PLCγ2Tyr1217磷酸化。重要的是,28a在体内对胶原蛋白诱导的关节炎(CIA)模型显示出有效的抗关节炎作用。每天一次的28a 60 mg / kg剂量水平组显示关节损伤和细胞浸润明显减少,而骨骼和软骨形态没有任何变化。
