A-3 hydrochloride 是一种细胞可渗透的、可逆的、ATP 竞争性非选择性拮抗剂。它抑制 PKA 、酪蛋白激酶 II 和肌球蛋白轻链激酶，Ki值分别为4.3 μM、5.1 μM和7.4 μM。它还抑制 PKC 和酪蛋白激酶 I 的活性，Ki分别为 47 μM 和 80 μM。

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[1]. 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[1].
