title: [Nootropic activity of nicotinamide and its structural analogs].
abstract: It is known that endogenic nicotinamide has a tranquilizing and stress-protective activity. The present investigations show the nootropic effect of this drug and its analogs nicomorpholine and acethylnicotinate on acute models of hypoxia and amnesia. The present results revealed that the observed nootropic activity of nicotinamide and its analogs is more expressed than this of piracetam, pyritinol and meclofenoxate. Having in mind the similarity of pharmacological effects of piracetam and nicotinamide (antihypoxic, antiamnestic and anxiolytic) we try if these drugs have electronic-structure similarities. The analysis revealed some similarity of these drugs' molecules in relation to the composition and distribution of polar centres pi- and p-electronic areas) distance between them, topography of separate molecule parts.
