Abstract
The cerebrovascular properties of 3,4,6,7,8,9-hexahydrodibenzo[b,d]furan-1(2H)-one O-(4-cinnamoyl)oxime (C21H21NO3, GIZ-272) were studied. The ability of GIZ-272 to improve the brain blood supply in rats subjected to global transient ischemia and to a lesser extent in animals with a hemorrhagic stroke model was established. The compound had cerebrovascular anti-ischemic activity comparable to that of Mexidol and a duration of action longer than that of nimodipine. It is important to note that GIZ-272 did not cause a decrease in blood pressure and was superior to both Mexidol and nimodipine in this respect. An analysis of the cerebrovascular effect of GIZ-272 using bicucullin indicated that the GABA-ergic system of cerebral vessels participated in implementation of the anti-ischemic effect of the compound.
