To elucidate the differences in mode and mechanism of action between YT-146, a highly selective adenosine A2 receptor agonist, and adenosine, we compared their effects on coronary circulation and myocardium and modifications of these effects by glibe

Nifedipine was synthesized by Bayer Germany in 1966 and considered for clinical use as a coronary vasodilator in patients with angina pectoris. Japanese investigators played a great part in the pre-clinical and clinical development of nifedipine. Pro

The “ball and chain” model has been shown to be suitable for explaining the rapid inactivation of voltage-dependent K+ channels. For theDrosophila Shaker K+ channel (ShB), the first 20 residues of the amino terminus have been identified as the in

Recently, we have cloned a cDNA for a putative cardiac inward rectifier K+ channel (RBHIK1) from rabbit cardiac muscles. However, it's single channel characteristics have remained unknown. Therefore, we investigated the single channel characteristics

In isolated canine right ventricular muscles, we investigated the differences in antagonisms by beta-blockers against the positive inotropic effects (PIEs) of isoproterenol, a nonselective agonist, and T-0509, a beta1-selective agonist. The selective

1. In the present study we estimated the KA value of endothelin-1 (ET-1) for ETA-receptors by a new method in which the level of expression of ETA-receptors in Xenopus oocytes was altered in a controlled way. 2. Kvl.2 (a delayed rectifier type K chan

We investigated the effects of the antiarrhythmic drugs, quinidine, disopyramide, flecainide, clofilium, verapamil, and the bradycardic drug, bertosamil, on the currents of the cloned K+ channels, KV1.2 (IK(V1.2)) and KV1.4 (IK(V1.4)), using the Xeno

1. The mechanisms of action of semotiadil fumarate, a novel Ca2+ antagonist, were examined by measuring the cytosolic Ca2+ level ([Ca2+]i) and force of contraction in porcine coronary arteries, and by determining [3H]-pyrilamine binding to bovine cer

Recently, pIcln has been reported to be a regulator of a swelling-induced chloride conductance. We have cloned a cDNA RCL-H1 from rabbit heart, of which primary structure is highly homologous to that of pIcln. Outwardly rectifying currents were recor

To investigate mechanisms for the receptor-mediated inhibition of a rat cardiac K+ channel clone (KV1.2), we coexpressed KV1.2 with a subtype of endothelin receptors (ETA) in Xenopus oocytes. Effects of endothelin ETA receptor stimulation were mimick
