Background

Description:

IC50: 17.2 μM

Bruton’s tyrosine kinase (BTK), a member of the BTK/Tec family of protein tyrosine kinases, is a cytoplasmic PTK involved in signal transduction pathways regulating growth and differentiation of B-lineage lymphoid cells. BTK participates in signal transduction pathways initiated by the binding of a variety of extracellular ligands to their cell-surface receptors. LFM-A13 is a BTK-specific 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].

Clinical trial: Up to now, LFM-A13 is still in the preclinical development stage.
