Cholinopositive effect of dilept (neurotensin peptidomimetic) as the basis of its mnemotropic effect.

Dilept eliminated learning disturbances in the extrapolation avoidance test, caused by chronic injections of scopolamine alone and in combination with madopar to rats. Dilept improved the dynamics of training and parameters of spatial memory impaired by olfactory bulbectomy (operation causing hypofunction of the central cholinergic system). The detected choline-positive effect of dilept together with pronounced dopaminergic activity necessitate its further development as a drug effective in positive and negative symptoms of schizophrenia and psychotic manifestations of Alzheimer's disease.
