| Description | PDE5-IN-13 (Compound 14b) inhibits phosphodiesterase 5 (PDE5A) with an IC50 of 3 nM and is applicable in pulmonary arterial hypertension research.

| Targets&IC50 | PDE11A:>100000 nM |
| In vitro | PDE5-IN-13's C3 cyanide group forms hydrogen bonds with D76 and H613 through a water molecule, thereby stabilizing the binding conformation of PDE5-IN-13 [1]. |
| In vivo | PDE5-IN-13 (1500 mg/kg, p.o.) shows no acute toxicity in mice [1]. In a rat model of Monocrotalin-induced pulmonary arterial hypertension, PDE5-IN-13 (5.0 mg/kg, p.o., daily for 21 days) is significantly more effective than Sildenafil citrate (10.0 mg/kg) at increasing mPAP (mean pulmonary artery pressure) and reducing RVHI (right ventricular hypertrophy index). |
