Prenylamine lactate is a drug formerly used in the treatment of angina pectoris. Prenylamine depletes myocardial catecholamine stores and has some calcium channel blocking activity.
Lincydomine is a smooth muscle relaxant, beneficial to the treatment of unstable angina pectoris, but also can open the respiratory tract of humans and guinea pigs.
Dopropidil is a new anti-angina pectoris calcium regulator, which has intracellular calcium antagonist activity and anti-ischemic effects in various predicted animal models.
Nicorandil-d4 is intended for use as an internal standard for the quantification of nicorandil by GC- or LC-MS. Nicorandil is an activator of sulfonylurea receptor 2B (SUR2B) linked to ATP-sensitive potassium channel Kir6.2 (EC50 = ~10 µM) and a nitric oxide (NO) donor. It is selective for SUR2B/Kir6.2 over the SUR2A/Kir6.2 channel (EC50 = >500 µM). Nicorandil activates soluble guanylate cyclase in a cell-free assay and relaxes partially depolarized isolated bovine coronary artery strips (EC50 = 4.4 µM). It decreases mean blood pressure, coronary resistance, and heart rate, as well as increases coronary sinus outflow, in dogs when administered intravenously at a dose of 1 mg/kg. Nicorandil increases survival and decreases infarct size in a rabbit model of myocardial ischemia-reperfusion injury induced by left coronary artery occlusion. Formulations containing nicorandil have been used in the treatment of angina pectoris.
Tedisamil is a blocker of K+ currents in cardiac tissues, exerts bradycardic effects. It is an antiarrhythmic drug with predominantly class III activity. It has shown clinical efficacy in angina pectoris.
Pheniprazine is an irreversible and nonselective monoamine oxidase inhibitor of the hydrazine chemical class. It was also used in the treatment of angina pectoris and schizophrenia.
Acebutolol D7 is a deuterium-labeled Acebutolol. Acebutolol is a selective antagonist of the β1 adrenergic receptor used in the treatment of angina pectoris, hypertension, and cardiac arrhythmias.
