IC50: 0.755-1.02 nM (BTK), 1.71-2.29 nM (TEC), 3.66-4.27 nM (BLK), 4.42-5.57 nM (BMX), 5.99-6.92 nM (LCK), 33.8-36.3 nM (Src), 0.187-0.198 μM (ITK),5.34-4.87 μM (JAK3)[1]
Ibrutinib-biotin (Compound 1-5) is a probe that consists of Ibrutinib linked to biotin via a long chain linker. Ibrutinib is a TEC family kinase inhibitor. The TEC kinase family is composed of five members, TEC, BTK (Bruton's Tyrosine Kinase), ITK (interleukin-2-inducible T-cell kinase)/EMT/TSK, BMX and TXK/RLK. The TEC family kinases participate in phosphotyrosine- mediated and phospholipid-mediated signaling systems. Many TEC family proteins are abundantly expressed in hematopoietic tissues, and play important roles in the growth and differentiation processes of blood cells[1].
