Abstract
Tridecapeptide neurotensin (NT) is known to exert the neuroleptic-like effects in case of its intracerebral administration. The group of systemically active dipeptides , acylprolyltyrosines, was constructed on the background of NT. Methyl ester of N-caproyl-L-prolyl-L-tyrosine (Dilept) was chosen for further development. The paper is dealing with main principles of Dilept'design and with analysis of the experimental data concerning its effect on the "translational" model of schizophrenia--the deficit of prepulse inhibition of the acoustic startle-reaction caused by either dopamine-mimetic, apomorphine, or by the uncompetitive NMDA-blocker, ketamine. Dilept was shown to attenuate these deficits both in case ofintraperitoneal and peroral administration. Dilept is considered as a potential antipsychotic.
