Selank, a Peptide Analog of Tuftsin, Attenuates Aversive Signs of Morphine Withdrawal in Rats.Bulletin of experimental biology and medicine · 2022
“Single intraperitoneal injection of Selank in an anxiolytic dose of 0.3 mg/kg reduced the total index of morphine withdrawal syndrome by 39.6%, significantly (р<0.0001) attenuated convulsive reactions, ptosis, and posture disorders, and 9-fold increased the tactile sensitivity threshold in morphine-dependent rats in comparison with the group of active control; at the same time, Selank was slightly inferior to diazepam in a dose of 2 mg/kg by pharmacological activity (the decrease in total index of morphine withdrawal syndrome by 49.3% and 13-fold increase in sensitivity threshold).”

Selank Inhibits Ethanol-Induced Hyperlocomotion and Manifestation of Behavioral Sensitization in DBA/2 Mice.Bulletin of experimental biology and medicine · 2016
“Selank that enhances activity of the endogenous opioid system (0.3 mg/kg, intraperitoneally), similar to the nonselective opiate receptor blocker naloxone (1.0 mg/kg, intraperitoneally), prevented the development of ethanol-induced (2.0 g/kg intraperitoneally) hyperlocomotion, in contrast to σ1-receptors agonist Afobazole (1.0 mg/kg, intraperitoneally) that did not inhibit ethanol-induced behavioral stimulation.”

“Pharmacological effects of intraperitoneal (i.p.) and intranasal (i.n.) administration of heptapeptide selank (300 μg/kg/day for 5 days), known to possess anxiolytic and nootropic properties, were compared by studying the elevated-plus-maze behavior of inbred BALB/c and C57BL/6 mice and measuring the binding of markers to NMDA and GABA receptors of brain.”
