A-3 hydrochloride

SKU: orb1219753

Description

A-3 hydrochloride is a potent, cell-permeable, reversible, ATP-competitive non-selective antagonist of various kinases. A-3 hydrochloride also inhibits PKC and casein kinase I with Ki values of 47 μM and 80 μM, respectively. A-3 hydrochloride against PKA (Ki=4.3 μM), casein kinase II (Ki=5.1 μM) and myosin light chain kinase (MLCK) (Ki=7.4 μM).A-3 hydrochloride inhibits MLC-kinase competitively with respect to ATP and that the Ki value is 7.4 μM, and it is also a competitive inhibitor of cAMP-dependent protein kinase, cGMP-dependent protein kinase, protein kinase C, casein kinase I, and casein kinase II, with respect to ATP, exhibits Ki values of 4.3 μM, 3.8 μM, 47 μM, 80 μM, and 5.1 μM, respectively.
