生物活性

製品説明 イブルチニブ (Ibrutinib (PCI-32765)) は、無細胞アッセイで IC50 が 0.5 nM の強力で選択性の高い Brutons チロシンキナーゼ (Brutons tyrosine kinase, Btk) 阻害剤であり、Bmx, CSK, FGR, BRK, HCKに対しても阻害活性を持ちます。 EGFR, Yes, ErbB2, JAK3 に対しては前者より比較的弱い活性を持ちます。イブルチニブは、P13I を含む一連の PROTAC の合成における Btk リガンドとして適用できます。
in vitro

Ibrutinib shows the potent and irreversible inhibitory effect and selectivity for Btk enzymatic activity. In BCR pathway-activated DOHH2 cell line, Ibrutinib inhibits autophosphorylation of Btk, phosphorylation of Btk's physiological substrate PLCγ, and phosphorylation of further downstream kinase, ERK with IC50 of 11 nM, 29 nM and 13 nM, respectively. [1] Ibrutinib exhibits a significant dose-dependent and time-dependent induction of cytotoxicity in chronic lymphocytic leukemia (CLL) cells. In addition, Ibrutinib induces cell death depending on caspase pathway activation and antagonizes the ability of CLL cells to proliferate after TLR signaling. [2] A recent study shows that Ibrutinib inhibits BCR-activated primary B cell proliferation with IC50 of 8 nM and results in inhibition of TNFα, IL-1β and IL-6 production in primary monocytes with IC50 of 2.6 nM, 0.5 nM and 3.9 nM, respectively. [3]
in vivo

In a collagen-induced arthritis model, Ibrutinib significantly reduces clinical arthritis scores reflecting paw swelling and joint inflammation by inhibiting B-cell activation. In a MRL-Fas(lpr) lupus model, Ibrutinib reduces renal disease and autoantibody production. [1] In an adoptive transfer TCL1 mouse model of CLL, Ibrutinib (25 mg/kg/day) causes a transient early lymphocytosis, and delays CLL disease progression. [4]

キナーゼアッセイ Kinase Assays
In vitro kinase IC50 values are measured using 33P filtration binding assay after 1 hour incubation of kinase, 33P-ATP, Ibrutinib, and substrate [0.2 mg/mL poly(EY)(4:1]. Assays are performed at Reaction Biology.
細胞アッセイ 細胞株 Chronic lymphocytic leukemia (CLL) cells
濃度 0.01-100 μM
反応時間 48 hours
実験の流れ

MTT (3'[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assays are performed to determine cytotoxicity. Briefly, cells (CLL B cells or healthy volunteer T cells or NK cells) are incubated for 48 hours with different concentrations of Ibrutinib, or vehicle control. MTT reagent is then added, and plates are incubated for an additional 20 hours before washing with protamine sulfate in phosphate-buffered saline. Dimethyl sulfoxide is added, and absorbance is measured by spectrophotometry at 540 nm in a Labsystems plate reader. Cell viability is also measured at various time points with the use of annexin/PI flow cytometry. Data are analyzed with Expo-ADC32 software package. Results are expressed as the percentage of total positive cells over untreated control. Experiments examining caspase-dependent apoptosis includes the addition of 100μM Z-VAD.
