生物活性

製品説明 LFM-A13 is a specific Bruton's tyrosine kinase (BTK) inhibitor with IC50 of 2.5 μM, >100-fold selectivity over other protein kinases including JAK1, JAK2, HCK, EGFR,and IRK.
in vitro

In BCL-1 cells, NALM-6 cells, or normal BALB/c splenocytes, LFM-A13 inhibits the enzymatic activity of BTK in BCL-1 cells without affecting the BTK protein expression levels [2] In human neutrophils, this compound decreases the tyrosine phosphorylation induced by fMet-Leu-Phe and inhibits the production of superoxide anions and the stimulation of adhesion, chemotaxis, and phospholipase D activity. [3]
in vivo

In BALB/c mice bearing BCL-1 leukemia, combination of LFM-A13 (50 mg/kg/day i.p.) and the standard triple-drug VPL prolongs the median survival time. [2] In primary myeloma-bearing SCID-rab mice, this compound inhibits osteoclast activity, prevents myeloma-induced bone resorption and suppresss myeloma growth. [4]
