ONO-4059

ONO-4059 is an inhibitor of Bruton's tyrosine kinase (BTK, IC50 = 2.2 nM). It is selective for BTK over LCK, LYN, and Fyn at 1 µM. ONO-4059 inhibits B cell proliferation and activation in vitro and reduces tumor growth in a TMD8 mouse xenograft model.Formal Name: 6-amino-7,9-dihydro-9-[(3R)-1-(1-oxo-2-butyn-1-yl)-3-pyrrolidinyl]-7-(4-phenoxyphenyl)-8H-purin-8-one.
