Olprinone
Based on 1 publication(s) in Google Scholar
Olprinone (Loprinone) is a potent and selective phosphodiesterase 3 (PDE3) inhibitor, with IC50 values of 150, 100, 0.35, and 14 μM against PDE1, PDE2, PDE3, and PDE4, respectively. Olprinone exerts comprehensive protective effects including anti-inflammatory, antioxidant, and anti-apoptotic activities by elevating intracellular cAMP levels and inhibiting the NF-κB and MAPK signaling pathways. Olprinone can be used in studies related to lung injury, spinal cord injury, myocardial ischemia-reperfusion injury, and cerebral ischemic injury.

Olprinone (Loprinone) hydrochloride (10 mM; 48-72 h) hydrate inhibits LPS (HY-D1056)-induced production of TNF-α and IL-6, and promotes the production of IL-10, in isolated rat alveolar macrophages[2].

Cell Line:Primary rat alveolar macrophages
-
Concentration:10 mM
-
Incubation Time:48, 72 h
-
Result:Significantly suppressed the levels of TNF-α and IL-6 at 48 h and 72 h.

Olprinone (0.2 mg/kg; i.p.; administered at 1 h and 6 h post-injury, followed by daily administration until day 9 post-injury; observation for 10 days) hydrochloride hydrate exerts effects of alleviating spinal cord inflammation, reducing cell apoptosis and improving hindlimb motor function in a mouse model of spinal cord injury[3].
Olprinone (0.2 mg/kg; i.v.; single administration; observation for 5 h) hydrochloride hydrate exerts effects of alleviating pulmonary oxidative stress, reducing pulmonary edema and inflammatory cell infiltration in a rabbit model of acute lung injury induced by meconium aspiration syndrome[4].
Olprinone (0.2 mg/kg; i.p.; single administration) hydrochloride hydrate exerts effects of reducing myocardial infarction size, anti-inflammation and anti-apoptosis in a rat model of myocardial ischemic injury[5].
Olprinone (0.2 mg/kg; i.p.; single administration; 5 minutes before reperfusion) hydrochloride hydrate exerts effects of reducing cerebral infarction volume, improving neurological deficits, anti-inflammation and anti-apoptosis in a rat model of cerebral ischemia/reperfusion injury[6].

Dosage:0.2 mg/kg
-
Administration:i.p.; single dose (30 minutes prior to LPS exposure); 6 h
-
Result:Significantly inhibited the LPS-induced neutrophil influx into the lungs.

Dosage:0.2 mg/kg
-
Administration:i.p.; 1 h and 6 h post-injury, then daily until day 9 post-injury (motor function assessment); 10 days
-
Result:Reduced the degree of spinal cord inflammation and tissue injury.
Attenuated neutrophil infiltration (reduced myeloperoxidase activity) and nitrotyrosine formation.
Decreased the expression of pro-inflammatory cytokines (TNF-α, IL-1β) and adhesion molecules (ICAM-1, P-selectin).
Inhibited NF-κB expression, p-ERK1/2, and p-p38 MAP kinase activation.
Decreased apoptosis, evident by reduced TUNEL staining, Fas ligand, and Bax expression, alongside preserved Bcl-2 expression.
Ameliorated the recovery of hind-limb function (BMS score).

Animal Model:Chinchilla rabbit (adult, 2.7 kg; meconium aspiration syndrome model via intratracheal meconium instillation)[4]
-
Dosage:0.2 mg/kg
-
Administration:i.v.; single dose; 5 h
-
Result:Reduced the numbers of neutrophils and eosinophils in the BAL fluid.
Decreased the formation of oxidation markers (conjugated dienes, TBARS, dityrosine, and lysine-lipid peroxidation products) in lung mitochondria.
Reduced lung edema (decreased wet/dry weight ratio) and prevented a decrease in total antioxidant status (TAS) in the lung homogenate and plasma.
Decreased TBARS levels in blood plasma and preserved cytochrome coxidase (COX) activity in the lung.
-
Animal Model:Wistar (male, 270-290 g, transient right hemisphere middle cerebral artery occlusion for 2 hours followed by 22 hours of reperfusion)[6]

Result:Reduced the infarct volume and improved the neurological deficit score.
Blocked the acute turning behavior significantly.
Suppressed the formation of nitrotyrosine and the expression of iNOS, IL-1β, and ICAM-1 in ischemic tissues.
Reduced levels of apoptosis (decreased TUNEL-positive cells and Bax expression, and maintained Bcl-2 expression).
