| biological activity | Disopyramide (Dicorantil) is a class IA anti-arrhythmic agent for both laboratory and atrial arrhythmias. Disopyramide blocked the rapid inward sodium current in the myocardium to prolong the duration of myocardial action potential. Disopyramide inhibits HERG-encoded potassium channels. Disopyramide also exhibits complex protein binding and a strong negative inotropic effect. |
| Use | cardiac medicine. Antiarrhythmic, suitable for supraventricular ventricular premature beat, all kinds of tachycardia atrial fibrillation. |
| production method | condensation and hydrolysis of 2-bromopyridine with benzonitrile and N,N-diisopropylchloroethylamine, and then with phosphoric acid to form salt that is to get the treatment of arrhythmia drug Dipyridamole. |
