Description

General description

A potent, cell-permeable, reversible, substrate competitive, and specific inhibitor of Bruton’s Tyrosine Kinase (BTK; IC₅₀ = 17.2 µM for human BTK in vitro and IC₅₀ = 2.5 µM for recombinant BTK). Also inhibits Polo-like kinase in an ATP-competitive manner (IC₅₀ = 10 µM and 61 µM for Plx1 and Plk3, respectively), and displays antitumor properties. Does not affect the enzymatic activity of other protein tyrosine kinases, including EGFR, HCK, IRK JAK1, and JAK3 even at concentrations of 278 µM. Enhances the chemosensitivity of BTK-positive B-lineage leukemia cells to ceramide- and vincristine-induced apoptosis.
