Biochem/physiol Actions

Udenafil (DA-8159) is an orally active, cGMP-competitive, potent and selective phosphodiesterase type 5 (PDE5) inhibitor (cellular PDE5 activity IC50 = 5.84/8.25 nM in rabbit/human platelets; IC50 = 53.3 nM/PDE6, 870 nM/PDE1, 52 μM/PDE3,101 μM/PDE2). Udenafil shows in vivo therapeutic efficacy in a rat model of monocrotaline-induced pulmonary hypertension (1 or 5 mg/kg bid po.) and induces penile erection in experimental animals in vivo (0.3-10 mg/kg po. in rabbits & rats).

DA-8159, a new Phosphodiesterase (PDE) 5 inhibitor, has exhibited potent erectogenic potential in a penile erection test in rats and anesthetized dogs. In this study, we investigated the mechanism of its erectogenic activity by measuring the activity of DA-8159 against

DA-8159 is a pyrazolopyrimidinone derivative showing potent and selective phosphodiesterase 5 (PDE5) inhibition. In the previous study, DA-8159 induced a dose-dependent increase in the intracavernous pressure (ICP) in anaesthetized dogs. The aim of this study was to investigate the effects

In this study, we evaluated the effects of oral administration of DA-8159, a selective phosphodiesterase-5 inhibitor, on the development of pulmonary hypertension (PH) induced by monocrotaline (MCT). Rats were administered either MCT (60 mg/kg) or saline. MCT-treated rats were divided
