Description
Damnacanthal (477-84-9) is a potent inhibitor of p56lck?tyrosine kinase activity (IC50?= 17 nM for inhibition of autophosphorylation). Displays 7- to 20-fold selectivity over p59fyn?and p60src?tyrosine kinases and > 40-fold to 100-fold selectivity over other kinases.1?Mobilizes intracellular Ca2+?in dermal fibroblasts.2?Inhibits LIM-kinase, impairing cell migration and invasion.3?A potent inhibitor of angiogenesis.4?Inhibits mast cell activation.5
