| Description | Win 58237 is an inhibitor of cyclic nucleotide phosphodiesterase (PDE) (Ki: 170 nM for PDE V), with vasorelaxant activity. |
| Targets&IC50 | PDE5:ki:170 nM |
| In vitro | Win 58237 is a competitive cGMP PDE V inhibitor from canine aorta(Ki : 170 nM). Win 58237 is a potent PDE V inhibitor isolated from vascular tissue (IC50 : 240 nM). It is a relatively less potent calmodulin-sensitive PDE I and cGMP-inhibitable cyclic AMP PDE III inhibitor ; but does inhibit cyclic AMP PDE IV with an IC50 value of approximately 300 nM. Win 58237 possesses vasorelaxant activity in the presence of an intact endothelium or nitric oxide. |
| In vivo | In vivo administration of Win 58237, at dosages ranging from 0.3 to 3.0 mg/kg intravenously, reduces mean arterial pressure in conscious spontaneously hypertensive rats, accompanied by a rise in vascular (aortic) cGMP content. Additionally, at a higher dosage of 10 mg/kg intravenously, Win 58237 elevates plasma cGMP levels from a baseline of 6.7 ± 1.0 to 31.4 ± 3.5 fmol/μL. |
