Ibrutinib (Synonyms: 伊布替尼; PCI-32765)

Ibrutinib (PCI-32765) 是一種不可逆的選擇性 Btk 抑制劑，IC₅₀ 值為 0.5 nM。Ibrutinib 可作為 Btk 配體，用于合成一系列 PROTAC 分子，如 P13I。P13I 作用于人 Burkitt’s 淋巴瘤 RAMOS 細(xì)胞，濃度為 10 和 100?nM 時(shí)，分別降解 73% 和 89% Btk。

生物活性

Ibrutinib (PCI-32765) is a selective, irreversible Btk inhibitor with an IC₅₀ of 0.5 nM^[1].

IC₅₀ & Target

IC50: 0.5 nM (Btk)

體外研究(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].

體內(nèi)研究(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].
