Descripción

General description

A cell-permeable protein kinase inhibitor that inhibits CaM kinase II (K_i = 1.8 nM), myosin light chain kinase (K_i = 17 nM), protein kinase A (K_i = 18 nM), protein kinase C (K_i = 25 nM), and protein kinase G (K_i = 20 nM). Also acts as a potent inhibitor (IC₅₀ = 3 nM) of the tyrosine protein kinase activity of the NGF receptor gp 140trk, the product of the trk protooncogene. Also inhibits the kinase activity of its transforming alleles, the trk oncogenes, and of the related neurotrophin receptors gp 145trkB and gp 145trkC. Induces apoptosis and cell cycle arrest by inhibiting Cdc2 and Cdc25c.
