RESUMEN
We studied in vitro and in vivo neuroprotective and antioxidant properties of neuroglutam, a new glutamic acid derivative. In experiments on immortalized mouse hippocampal cell line HT22, neuroglutam exhibited a neuroprotective effect in the model of oxidative stress after its introduction, both before and after H2O2. In vivo study on animals treated with neuroglutam against the background of cerebral ischemia modeled by irreversible occlusion of the common carotid arteries showed that plasma level of TBA-active products was significantly lower and activities of cell antioxidant enzymes (superoxide dismutase and catalase) were higher than in control animals receiving saline under the same conditions.

A comparative analysis of the effect of phenyl derivatives of glutamic (RGPU-135) and gamma-aminobutyric acid (Phenibut) on cerebral blood flow, vasodilatory endothelial function and the number of circulating endothelial cells desquamated in animals after irreversible occlusion of the common carotid arteries. It was found that animals treated prophylactically by RGPU-135, after occlusion of the common carotid arteries have higher cerebral blood flow and lower the severity of endothelial dysfunction than in animals treated with Phenibut.
