InvivoChem Cat #:V3392CAS #:1633350-06-7Purity >=98%Description: (+/-)-Zanubrutinib is a racemic mixture of Zanubrutinib (formerly known as BGB-3111) which is a novel, highly selective, second generation BTK inhibitor, currently under clinical investigation in hematological cancers. In both biochemical and cellular assays, BGB-3111 demonstrated nanomolar BTK inhibition activity. In several MCL and DLBCL cell lines, BGB-3111 inhibited BCR aggregation-triggered BTK autophosphorylation, blocked downstream PLC-gamma2 signaling, and potently inhibited cell proliferation. In comparison with ibrutinib, BGB-3111 showed much more restricted off-target activities against a panel of kinases, including ITK. While ibrutinib significantly inhibited rituximab-induced NK cell IFN-gamma secretion and in vitro cytotoxicity on mantle cell lymphoma cells, BGB-3111 was at least 10-fold weaker than ibrutinib in inhibiting rituximab induced ADCC, consistent with its weak ITK inhibition activity.
