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 Ramos, Jeko-1, Daudi cells, respectively), good kinase selectivity and inhibited BTK Y223 auto-phosphorylation and PLCγ2 Tyr1217 phosphorylation. Importantly, 28a showed efficacy anti-arthritic effect on collagen-induced arthritis (CIA) model in vivo. 28a 60 mg/kg dose level once a day group displayed markedly reduced joint damage and cellular infiltration without any bone and cartilage morphology change.

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。
