描述 | Bruton’s tyrosine kinase (BTK), an essential component of the B-cell antigen receptor (BCR) pathway, has emerged as novel target in the treatment of B-cell malignancies . Zanubrutinib is a selective BTK inhibitor. It demonstrates nanomolar BTK inhibition activity in both biochemical and cellular assays. In several MCL and DLBCL cell lines, Zanubrutinib inhibits BCR aggregation-triggered BTK autophosphorylation, blocks downstream PLC-γ2 signaling, and potently inhibits cell proliferation. Zanubrutinib induces dose-dependent anti-tumor effects against REC-1 MCL xenografts engrafted either subcutaneously or systemically via tail vein injection in mice. In the systemic model, the median survival of Zanubrutinib 25 mg/kg BID group is significantly longer than those of both PCI-32765 50 mg/kg QD and BID groups. In an ABC-subtype DLBCL (TMD-8) subcutaneous xenograft model, Zanubrutinib also demonstrates better anti-tumor activity than PCI-32765. Preliminary 14-day toxicity study in rats shows that Zanubrutinib is very well tolerated and maximal tolerate dose (MTD) is not reached when it is dosed up to 250 mg/kg/day .[1] | ||
