Phosphodiesterase-IN-5 is a potent and orally bioavailable selective phosphodiesterase 10A (PDE10A) inhibitor, with an IC50 value of 6.2 nM. It demonstrates over 1612-fold selectivity for other PDE subtypes. By blocking the cAMP/PKA/CREB signaling pathway, it inhibits myofibroblast differentiation and shows significant antifibrotic effects in a Bleomycin (BLM)-induced mouse model of pulmonary fibrosis (PF). Phosphodiesterase-IN-5 is applicable for pulmonary fibrosis research.

| In vitro | Phosphodiesterase-IN-5 (compound QC-3) (5-20 μM; 48 hours) exhibits antifibrotic activity in TGF-β1-stimulated MRC-5 cells by activating the cAMP/PKA/CREB pathway, which inhibits myofibroblast differentiation and ECM deposition. Phosphodiesterase-IN-5 binds to the PDE10A catalytic domain, forming a hydrogen bond with Gln726 and a hydrophobic interaction with Ile692, while the 6-F substituent forms a halogen bond with Asp674 via a water molecule. |
| In vivo | Phosphodiesterase-IN-5 (10 mg/kg, oral gavage, once daily for 21 days) demonstrates significant antifibrotic activity by inhibiting myofibroblast differentiation through the cAMP/PKA/CREB signaling pathway in a BLM-induced mouse model of pulmonary fibrosis. |
| Storage | Powder: -20°C for 3 years | In solvent: -80°C for 1 year Shipping with blue ice/Shipping at ambient temperature. |
