Introduction of 936563-96-1 :

Ibrutinib (PCI-32765) is a selective, irreversible Btk inhibitor with an IC50 of 0.5 nM[1]. IC50 & Target: IC50: 0.5 nM (Btk) In Vitro: Ibrutinib (PCI-32765) selectively inhibits B-cell signaling and activation. It inhibits autophosphorylation of Btk (IC50=11 nM), phosphorylation of Btk's physiological substrate PLCγ (IC50=29 nM), and phosphorylation of a further downstream kinase, ERK (IC50=13 nM)[1].
Ibrutinib (PCI-32765) inhibits BCR-activated primary B cell proliferation (IC50=8 nM). Following FcγR stimulation, Ibrutinib (PCI-32765) inhibits TNFα, IL-1β and IL-6 production in primary monocytes (IC50=2.6, 0.5, 3.9 nM, respectively)[3].
Ibrutinib binds C481 (Cysteine481) of BTK with an ideal IC50 of 0.5 nM. Ibrutinib cannot form a covalent bond with the hydroxyl group of serine, C481S mutation increases the IC50 against BTK-C481S phosphorylation from 2.2 nM to 1 μM[4]. In Vivo: Ibrutinib (PCI-32765) (3.125-50 mg/kg, p.o.) reduces the level of circulating autoantibodies and completely suppresses disease in mice with collagen-induced arthritis. Ibrutinib (PCI-32765) inhibits autoantibody production and the development of kidney disease in the MRL-Fas(lpr) lupus model. Ibrutinib (PCI-32765) (3.125-50 mg/kg, p.o.) reduces renal disease and autoantibody production in MRL-Fas(lpr) mice[1]. Ibrutinib (PCI-32765) (0.1 μM) inhibits activation-induced proliferation of CLL cells, induces selective cytotoxicity in B cells compared with T cells, but alters activation induced T-cell cytokine production[2]. Ibrutinib (PCI-32765) dose-dependently and potently reverses arthritic inflammation in a therapeutic CIA model with an ED50 of 2.6 mg/kg/day. Ibrutinib (PCI-32765) also prevents clinical arthritis in CAIA models[3].
