title: [Gastroprotective activity of modified glutamyl-tryptophan dipeptide analogs and melatonin].
abstract: The gastroprotective action of synthetic dipeptides glutamyl-tryptophane (EW), iso-valeroyl-glutamyl-tryptophane (ivEW) and nicotinoyl-glutamyl-tryptophane (nEW) in comparison to melatonin was studied in experiments on male with the model indometacine and starvation stress-induced stomach ulcers. It was shown, that EW and melatonin exhibit antiulcer activity upon preventive intragastric administration on the model of starvation stress stomach ulcers. At the same time, ivEW, nEW, EW and melatonin exhibit antiulcer activity during the treatment of model indometacine-induced stomach ulcers. The maximum gastroprotective action was observed for ivEW on the model of indomethacin-induced stomach ulcer. The therapeutic efficiency of substances studied is based on their cytoprotective, antioxidant and immunomodulating action.
