| Description | Gisadenafil (UK-369003), a selective inhibitor of phosphodiesterase 5 (PDE5) with an IC50 of 3.6 nM, prevents the degradation of cGMP. |
| Targets&IC50 | PDE5A:3.6 nM, PDE1A:9.1 μM |
| In vitro | In COS-7 cells, the IC50 of Gisadenafil for PDE1A is 9.1 μM, an approximately 2500-fold difference in selectivity[2]. |
| In vivo | In male Tat-transgenic mice, Gisadenafil (2 mg/kg; i.p.) restores the dilation of small (<25 μm) arterioles following hypercapnia, although it fails to restore full dilation of larger (>25 μm) vessels. Gisadenafil largely restores the normal increase in cortical flow following hypercapnia in Tat-tg mice (17.5% above baseline)[2]. |
