Protective effect of a new prostacyclin analogue OP-2507 against cerebral anoxia and edema in experimental animals.

Protective effects of OP-2507 [15-cis-(4-propylcyclohexyl)-16,17,18,19,20-pentanor-9-deoxy -9 alpha, 6-nitrilo-PGF1 methyl ester] against cerebral anoxia and edema were investigated in a variety of experimental models in mice and rats. OP-2507 given s.c. or p.o. led to a consistent and dose-dependent prolongation of survival time against cerebral anoxia in hypobaric and normobaric hypoxia, KCN-induced anoxia and decapitation-induced gasping. Furthermore, treatment with 0.03-0.1 mg/kg s.c. or 0.3 mg/kg p.o. of OP-2507 was found to be effective against the changes of cerebral energy metabolites and cyclic nucleotides in hypoxic brain. In brain ischemia induced by bilateral ligation of common carotid arteries of rats, a reduction in specific gravity of cortex and an increase in water content of brain were observed, in accordance with changes of cerebral energy metabolites. These edematous and biochemical changes were prevented by the treatment with 0.01-0.03 mg/kg s.c. of OP-2507. These results indicate a potential usefulness of OP-2507 in protecting the brain from oxygen insufficiency resulting from cerebral ischemia.[1]
