Description
Bepridil (74764-40-2) is a clinically useful calcium channel blocker with antianginal activity.1 It has recently been shown to possess potent activity against SARS-CoV-2 in vitro.2 Bepridil was also able to provide protection from Ebola virus3 and other filoviruses in a mouse model4.
Uses
antineoplastic, alkylating agent
Uses
Bepridil Hydrochloride is a calcium channel blocker. It also activates mitochondrial ATP-sensitive KATP channelsBepridil Hydrochloride is an antiarrhythmic and antihypertensive agent and used for treating atrial fibrillation.
Definition
ChEBI: The hydrochloride monohydrate of bepridril.
brand name
Bepadin
(Medpointe); Vascor (Johnson & Johnson).
General Description
Bepridil hydrochloride,β-[(2-methylpropoxy)methyl]-N-phenyl-N-(phenylmethyl)-1-pyrrolidineethylamine hydrochloride (Vascor), is a secondgenerationalkylamine-type channel blocker, structurallyunrelated to the dihydropyridines. Its actions are less specificthan those of the three prototypical channel blockers,verapamil, diltiazem, and nifedipine. In addition to being aCa
2+ channel blocker, it inhibits sodium flow into the hearttissue and lengthens cardiac repolarization, causing bradycardia.Caution should be used if it is given to a patient withhypokalemia. Bepridil hydrochloride is used for stableangina. The drug has a half-life of 33 hours and is highlybound to protein (99%).
Hazard
Moderately toxic by ingestion.
Biochem/physiol Actions
Non-selective calcium channel blocker and class IV antiarrhythmic agent; inhibits Na+-Ca2+ exchange; inhibits growth of brain tumor cells in vitro.
Mechanism of action
In addition to class IV effects, bepridil also
shows class I effects. The substance is active
against both supraventricular and ventricular arrhythmias
