Limaprost

Research use only, not for human use.

Limaprost is an analog of PGE1 with structural modifications intended to give it a prolonged half-life and greater potency.It is a potent and orally active vasodilator.?Limaprost increases blood flow and inhibits platelet aggregation.?Limaprost can be used for pain relief, has antianginal effects, and has potential for ?ischaemic symptoms treatment.

Limaprost inhibits the IL-1-mediated induction of nerve growth factor (NGF) in a concentration-dependent manner with an IC50 value of 70.9 ?nMhuman IVD cells.

Limaprost (OP1206) given orally at more than 100 μg/kg relieves Argipressin-induced ST depression of rat electrocardiogram (ECG). Intra-coronary injection of Limaprost (OP1206; 1-100 ng/kg) in dogs results in a remarkable increase of coronary blood flow without any influence on heart rate, blood pressure, myocardial oxygen consumption and redox potential. Resistance in both large and small vessels of dog coronary artery is decreased by intravenous injection of Limaprost (OP1206; 1-3 mg/kg).Platelet aggregation, adhesiveness, bleeding time, and thrombocytopenia induced by ADP and collagen infusion in guinea-pigs are inhibited by oral administration of Limaprost (OP1206) at the same doses or doses less than those relieving Argipressin-induced ST depression of ECG.
