HA-1004 diHClide 是 PKA、PKC、cGKI、MYLK 和钙通道蛋白的抑制剂HA-1004 被证明是两种环核苷酸依赖性蛋白激酶（环 GMP 依赖性蛋白激酶和环 AMP 依赖性蛋白激酶）的有效抑制剂蛋白激酶和 Ki 值分别为 1.4 和 2.3 microM。

HA-1004 dihydrochloride?is an inhibitor of PKA, PKC, cGKI, MYLK, and calcium channel proteinHA-1004, was shown to be a potent inhibitor of two cyclic nucleotide-dependent protein kinases, cyclic GMP-dependent protein kinase and cyclic AMP-dependent protein kinase and the Ki values were 1.4 and 2.3 microM, respectively.?HA-1004 relaxed rabbit aortic strips contracted by various agonists and with similar ED50 values.?Phenotolamine, propranolol and atropine did not affect this HA-1004-induced relaxation, thereby suggesting that this compound does not act through these membrane receptor associated mechanisms.?HA-1004 shifted the dose-response curve for CaCl2 to the right in a competitive manner in depolarized rabbit renal arterial strips.?This compound also relaxed the A-23187 and phenylephrine-induced contractions elicited in Ca++-free solution.?HA-1004 exerts its action at the intracellular or submembranal level.?This vasodilator has little effect on actomyosin adenosine triphosphatase and Ca++-calmodulin-dependent myosin light chain kinase.?Studies using its derivatives with various lengths of alkyl chain (C0-C6) indicated that the potencies of these compounds, as vasorelaxants, correlated well with their potential to inhibit cyclic nucleotide-dependent protein kinase.?HA-1004 should be a useful tool for investigating in smooth muscle, regulatory mechanism(s) by second messengers, cyclic AMP and cyclic GMP.
