The development of methods of drug therapy and rehabilitation in different periods of ischemic cerebral lesion is currently an urgent problem. Our study was aimed to investigate the pharmacokinetics and anti-ischemic effect of the new 4-phenylpyrrolidone-2 derivative in rats. To study the drug pharmacokinetics, the Wistar rats were once administered with the substance at a dose of 250 mg/kg, then, the substance distribution in blood and cerebral cortex was evaluated. Elimination half-life value was determined, which was 83.2 min. The substance remained in the brain tissue for 24 hours. To assess the anti-ischemic effect, the stroke was modeled by endovascular middle brain artery transition occlusion, and the drug was administered intravenously for 5 days at two doses, 250 and 125 mg/kg. After that the lesion focus volume was evaluated by MRI, as well as the neurological deficit severity, locomotor and explorative behavior. The studied drug significantly decreased the neurological deficit in model animals compared to control group (1.72 vs 4.4, p < 0.05). According to the MRI data, the effect on the ischemic focus was negligible, while the explorative behavior significantly increased under the influence of the 4-phenylpyrrolidone-2 derivative (hole board test, horizontal activity 12.1 ± 6.8, 22.5 ±10.5, p < 0.05). The data obtained allow us to conclude that the studied substance penetrates the blood-brain barrier (BBB), and accumulates in the brain tissue promoting the neurological deficit correction and increasing the explorative behavior in the ischemic stroke model animals.
