Background |
Ibrutinib is a small molecule BTK inhibitor that selectively covalently binds to the cysteine residue (Cys-481) on the active site of BTK, irreversibly inhibits the activity of BTK, thereby inhibiting BCR activation of signaling pathways. |
Biological Activity |
Ibrutinib (PCI-32765) 是选择性, 不可逆的 Btk 抑制剂, IC50 值为 0.5 nM。 |
IC50 |
IC50: 0.5nM (Btk) |
In Vitro |
依鲁替尼(PCI-32765)选择性抑制B细胞信号传导和激活。它抑制Btk的自身磷酸化(IC50 = 11 nM),Btk生理底物PLCγ的磷酸化(IC50 = 29 nM),以及进一步下游激酶ERK的磷酸化(IC50 = 13 nM)[1]。依鲁替尼(PCI-32765)抑制BCR活化的原代B细胞增殖(IC50 = 8nM)。在FcγR刺激后,依鲁替尼(PCI-32765)抑制原代单核细胞中TNFα,IL-1β和IL-6的产生(IC50分别为2.6,0.5,3.9nM)[3]。 |
In Vivo |
依鲁替尼(PCI-32765)(3.125-50 mg / kg,po)降低循环自身抗体的水平,并完全抑制胶原诱导的关节炎小鼠的疾病。依鲁替尼(PCI-32765)抑制MRL-Fas(lpr)狼疮模型中的自身抗体产生和肾病的发展。依鲁替尼(PCI-32765)(3.125-50 mg / kg,po)可减少MRL-Fas(lpr)小鼠的肾脏疾病和自身抗体产生[1]。依鲁替尼(PCI-32765)(0.1μM)抑制激活诱导的CLL细胞增殖,诱导B细胞选择性细胞毒性,与T细胞相比,但改变激活诱导的T细胞细胞因子的产生[2]。依鲁替尼(PCI-32765)剂量依赖性地且有效地逆转治疗性CIA模型中的关节炎性炎症,ED50为2.6mg / kg /天。依鲁替尼(PCI-32765)也可预防CAIA模型中的临床关节炎[3]。 |
