PDE4B/D-IN-5
PDE4B/D-IN-5 (Compound P32) is a peripherally restricted, oral active inhibitor of PDE4B and PDE4D with extremely low blood-brain barrier penetration, with IC50 values of 3.4 nM and 2.2 nM, respectively. PDE4B-IN-8 inhibits the production of TNF-α. PDE4B/D-IN-5 significantly reduces the Bax/Bcl2 ratio, and alleviates oxidative stress by decreasing MPO activity and NO levels. PDE4B/D-IN-5 exhibits anti-inflammatory, antioxidant, and anti-apoptotic activities. PDE4B/D-IN-5 can be used for the research of acute lung injury.

PDE4B/D-IN-5 potently inhibits recombinant PDE4B1 in an in vitro fluorescence polarization enzyme activity assay (IC50 = 3.4 nM)[1].
PDE4B/D-IN-5 (15 μM; up to 90 min) exhibits high metabolic stability in rat liver microsomes, with 94.8% remaining after 60 min, a half-life of 5.5 h, and a clearance as low as 0.0021 mL min−1 mg−1[1].
PDE4B/D-IN-5 (1-4 μM; 1 h) dose-dependently inhibits LPS-stimulated TNF-α production in RAW264.7 mouse macrophages[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

PDE4B/D-IN-5 (6-12 mg/kg; i.p.; daily; 5 days) dose-dependently attenuates LPS-induced acute lung injury in male C57BL/6 mice via anti-inflammatory, antioxidant, and antiapoptotic effects mediated by the cAMP-Epac pathway[1].

Dosage:6 mg/kg; 12 mg/kg
-
Administration:i.p.; daily; 5 days

Result:Reduced lung erythema, enlargement, alveolar damage, interstitial edema, and inflammatory cell infiltration.
Showed a significant reduction in Smith lung injury scores in the 12 mg/kg group compared to the model group.
Reduced lung wet/dry weight ratios with a dose-dependent trend.
Reduced bronchoalveolar lavage fluid (BALF) neutrophil counts more effectively than dexamethasone, with a dose-dependent effect.
Attenuated lung myeloperoxidase (MPO) activity more potently than dexamethasone, with a dose-dependent effect.
Reduced lung tissue nitric oxide (NO) levels to values comparable to dexamethasone.
Suppressed BALF tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) levels in a dose-dependent manner, with the 12 mg/kg group showing greater suppression than dexamethasone.
Dose-dependently elevated lung tissue cAMP levels, with the 12 mg/kg group showing the most pronounced effect.
Induced a dose-dependent, significant upregulation of Epac1 protein expression.
Significantly decreased the Bax/Bcl2 ratio, indicating suppression of mitochondrial apoptosis.
Showed no statistically significant changes in p-PKA/PKA or p-AMPK/AMPK ratios.
