CAS No.: 81338-23-0
Target:
Research Areas:
D-AP7 is a specific NMDA receptor antagonist with inhibitory activity against epileptiform activity. D-AP7 attenuated neuronal activation in spot activity by reducing the duration and number of exogenously induced bursts. D-AP7 also increased the amplitude of secondary action potentials, which may restore neuronal activity in some epileptiform bursts. D-AP7 showed anxiogenic effects and impaired memory consolidation in passive avoidance learning .

Target:
Research Areas:
AFD-21 maleate is a drug with antiarrhythmic activity. AFD-21 maleate inhibits sodium channels by binding to sodium channels in an inactive state, with both use-dependent and voltage-dependent effects. The unbinding rate of AFD-21 maleate is similar to that of Class I antiarrhythmic drugs with moderate kinetics. AFD-21 maleate can cause a slight prolongation of the action potential duration and significantly reduce the maximum rise rate of the action potential at certain concentrations. AFD-21 maleate also showed use-dependent blocking effects as stimulation frequency increased .
Target:
Research Areas:
Etafenone is an antiarrhythmic agent and vasodilator. Etafenone exerts β-adrenergic agonistic effects. Etafenone inhibits the automaticity of sinoatrial nodes, atrioventricular junctions and Purkinje fibers, prolongs action potential duration and refractory period, slows the rising rate of action potentials, and prolongs conduction time. Etafenone enhances collateral circulation after coronary occlusion and suppresses ventricular premature beats. Etafenone delays ischemic myocardial energy imbalance, improves the recovery of high-energy phosphates after ischemia, and reduces myocardial oxygen consumption. Etafenone can be used in research related to ischemic heart disease, arrhythmia and angina pectoris .
