ABSTRACT:
The invention refers to the field of medicine and may be applied as a substance stimulating the functional activity of hepatocytes, restoring the synthesis of non-specific proteins, normalising metabolism activating the processes of proliferation and differentiation of the liver cells. There is proposed a new compound -tetrapeptide lysyl-glutamyl-aspartyl-alanine of the general formula Lys-Glu-Asp-Ala [SEQ ID NO:1]. There is proposed a pharmaceutical composition capable of stimulating the functional activity of hepatocytes and a pharmaceutical peptide substance containing as its active base a therapeutically effective quantity of tetrapeptide of the formula Lys-Glu-Asp-Ala [SEQ ID NO:1] or one of its salts intended for parenteral administration. There is proposed a method of stimulating the functional activity of hepatocytes including therapeutic administration to a patient of the pharmaceutical peptide substance in doses 0.01–100 μg/kg of the body weight at least once a day during a period required for attaining a therapeutic effect.
