| Hazard Information | Back Directory | [Description]
LFM-A13 (244240-24-2) is a selective inhibitor of Bruton’s tyrosine kinase (BTK) – IC50‘s = 2.5 μM (recombinant BTK) and 17.2 μM (human BTK).1,2 It has also been shown to inhibit Polo-like kinase (PLK) – IC50 = 61 μM for human PLK3.3 LFM-A13 displayed no activity (concentrations up to 278 μM) at JAK1, JAK3, HCK, EGFRK and IRK2 or CDK1-3, CHK1, IKK, MAPK1, SAPK2a and ten other tyrosine kinases.3 | [Uses]
LFM-A13 is a potent inhibitor of Polo-like kinase (PLK), used for anti-breast cancer activity. Also a specific Bruton’s tyrosine kinase inhibitor. | [in vitro]
lfm-a13 inhibited recombinant btk expressed in a baculovirus expression vector system. besides its remarkable potency in btk kinase assays, lfm-a13 was also found to be a highly specific inhibitor of btk. even at very high concentrations, lfm-a13 did not affect the activity of other protein tyrosine kinases [1]. | [in vivo]
lfm-a13 exhibited a favorable pharmacokinetic behavior which was not adversely affected by the standard chemotherapy drugs and significantly improved the chemotherapy response and survival outcome of bcl-1 leukemia cells challenged mice. while only 14% of mice treated with the standard triple-drug combination treatment became long-term survivors, 41% of mice treated with this combination plus lfm-a13 survived long-term [2]. | [IC 50]
