Opis

Opis ogólny

A cell-permeable, potent, reversible, and selective inhibitor of p56^lck tyrosine kinase. Inhibits p56^lck autophosphorylation (IC₅₀ = 17 nM) and phosphorylation of an exogenous peptide by p56^lck (IC₅₀ = 620 nM). Exhibits over 100-fold greater selectivity for p56^lck over PKA and PKC, 40-fold greater selectivity for p56^lck over EGF receptor kinase, c-ErbB2, insulin receptor kinase, and PDGF receptor kinase, and 7 - 20-fold greater selectivity for p56^lck over p60^src and p59^fyn. Inhibition of p56^lck is not significantly affected by the presence of sulfhydryl reagents. Also known to have antimalarial properties and to reverse the phenotype of ras-transformed cells.

A cell-permeable, potent, reversible, and selective inhibitor of p56^lck tyrosine kinase activity. Inhibits p56^lck autophosphorylation (IC₅₀ = 17 nM) and phosphorylation of an exogenous peptide by p56^lck over PKA and PKC and >40 fold selectivity for p56^lck over EGF, c-erbB2, insulin, and the PDGF receptor tyrosine kinases. In addition, damnacanthal exhibits 7-20 fold selectivity for p56^lck over pp60^src and pp59^fyn. Inhibition of p56^lck by damnacanthal appears to be reversible, not time-dependent and not significantly affected by the presence of sulfhydryl reagents. Also known to have antimalarial properties, and to reverse the phenotype of ras-transformed cells.
