PDE5-IN-1
PDE5-IN-1 is an orally active, selective PDE5 inhibitor with an IC50 of 5.6 nM. PDE5-IN-1 forms hydrogen bond interactions with the Q817 residue in the catalytic domain of PDE5, and aromatic π-π stacking interactions with the F820 residue. PDE5-IN-1 exerts anti-cardiac hypertrophy and vasodilatory effects, reduces mean pulmonary arterial pressure and right ventricular hypertrophy index. PDE5-IN-1 can be used in the research of pulmonary arterial hypertension.

Biological Activity
PDE5-IN-1 (compound 2) (15 min) shows remarkable selectivity for PDE5A over other PDE families, with selectivity indices ranging from 10 (vs PDE6A) to >1700 (vs PDE1B, PDE3A, PDE7A1, PDE9A2)[1].
PDE5-IN-1 has weak inhibitory effects on major human hepatic CYP isoenzymes, with only moderate inhibition of CYP1A2 (IC50 = 7.6 μM) and no significant inhibition of six other key isoenzymes[1].
PDE5-IN-1 shows weak inhibition of the hERG potassium channel, with an IC50 >10 μM[1].
PDE5-IN-1 (0.5 μM) is stable in both rat and human liver microsomes, with significantly longer half-lives than the positive control midazolam[1].

Animal Model:Wister rats (8 weeks old, 180-220 g, MCT-induced PAH)[1]
-
Dosage:5.0 mg/kg
-
Administration:p.o.; daily; 3 weeks
-
Result:Reduced mean pulmonary artery pressure (mPAP) to 18.65 mmHg, a statistically significant decrease compared to the PAH model group's 32.74 mmHg.
Reduced right ventricle hypertrophy index (RVHI) to a statistically significant level compared to the model group.
Exhibited better effects on both mPAP and RVHI than sildenafil citrate at 10.0 mg/kg.
