N-Desethyl vardenafil is a metabolite of vardenafil , a phosphodiesterase 5 inhibitor, that is formed by the action of cytochrome P450 (CYP)3A4 and CYP3A5.
N-Desmethyl sildenafil is a major metabolite of sildenafil . N-Desmethyl sildenafil is formed via oxidative metabolism of sildenafil by the cytochrome (CYP) P450 isoforms CYP3A4, CYP3A5, and CYP3A7.
(3S)-hydroxy Quinidine is an active quinidine metabolite. Quinidine, an antiarrhythmic agent, undergoes rapid first-pass metabolism by the cytochrome P450 (CYP) isoforms CYP3A4, CYP2C9, CYP2E1, and CYP3A5, with CYP3A4 being the most active enzyme in the (3S)-hydroxy quinidine formation. (3S)-hydroxy Quinidine prolongs repolarization of canine Purkinje fibers in vitro and prevents ventricular fibrillation and ventricular tachycardia after coronary reperfusion in isolated rat hearts in a dose-dependent manner.
6β-hydroxy Eplerenone is a major metabolite of the mineralocorticoid receptor antagonist eplerenone .1 It is formed from eplerenone by the cytochrome P450 (CYP) isoform CYP3A4.

6β-Hydroxy Prednisolone, the active metabolite of prednisone and a derivative of prednisolone, is predominantly synthesized via the cytochrome P450 (CYP) isoform CYP3A4 and, to a lesser extent, CYP3A5.
Desethoxy quetiapine, an active metabolite of the atypical antipsychotic quetiapine, primarily forms through the action of the cytochrome P450 (CYP) isoform CYP3A5. This compound binds to dopamine D2 receptors with an IC50 value of 1,330 nM. In vivo, desethoxy quetiapine at dosages of 20 and 40 mg/kg mitigates dopamine receptor agonist apomorphine-induced climbing behavior and ameliorates swimming deficits in mice, showcasing its potential modulatory effects on dopamine-mediated behaviors.
N-Desethyl Vardenafil (Standard) is the standard substance of N-Desethyl Vardenafil, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. N-Desethyl vardenafil is a metabolite of vardenafil , a phosphodiesterase 5 inhibitor, that is formed by the action of cytochrome P450 (CYP)3A4 and CYP3A5.
