PDE5-IN-13
PDE5-IN-13 (Compound 14b) inhibits phosphodiesterase 5 (PDE5A) with an IC50 of 3 nM. PDE5-IN-13 is a potential candidate for PAH (pulmonary arterial hypertension) research. PDE5-IN-13 has high selectivity for targets over PDE1, PDE2, PDE3, PDE4, PDE7, PDE8, PDE9, PDE10, and PDE11. PDE5-IN-13 is orally active.

The C3-cyanide group of PDE5-IN-13 forms hydrogen bond bridges with D764 and H613 through water molecules, which stabilizes the binding conformation of PDE5-IN-13[1].
The [1-(pyridin-2-yl)ethyl] amino side chain at C8-position of PDE5-IN-13 is located near the solvent-exposed region, and the hydrophilic pyridine ring can interact with the solvent region, enhancing inhibitory affinity of PDE5-IN-13[1].
PDE5-IN-13 inhibitor displays weak inhibition against the CYP1A2, CYP2D6, and CYP3A4 with IC50s above 50 μM, and for CYP2C19 and CYP2C9 is 4.63 and 9.76 μM, respectively[1].
PDE5-IN-13 exhibits much weaker inhibitory activity toward hERG channel with an IC50 above 30 μM[1].

PDE5-IN-13 (5.0 mg/kg, p.o., daily, 21 days) shows a remarkable increase in mPAP (pulmonary arterial pressure) and decrease in RVHI (right ventricular hypertrophy index) than Sildenafil citrate (HY-15025A) (10.0 mg/kg) in a Monocrotaline (HY-N0750)-induced PAH rat model[1].
