Lck Inhibitor (compound 25) exhibits good potency in the T-cell receptor-induced IL-2 secretion assay (IL-2, IC 50 =0.46 μM) and also inhibits subsequent T-cell proliferation (T-cell prolif, IC 50 =0.53 μM) in the same human T-cells. Lck Inhibitor also inhibits a human mixed lymphocyte reaction (huMLR) with a 10-fold increase in potency as compared to the other invitro cell assays utilizing purified human cells. Lck Inhibitor also displays inhibition of a mechanism-based biochemical cell assay probing Lck-dependent TCR-chain phosphorylation (TCR-chain). Lck Inhibitor shows a 10-fold reduction in potency when IL-2 is induced in a receptor-independent fashion by stimulating with phorbo lester and calcium ionophore (PMA/iono). Lck Inhibitor exhibits a similar level of potency when tested in a general proliferation assay using the human T-cell line, Jurkat (JKT).
