The present invention refers to biochemistry, namely to new peptide compounds having the ability to selectively block the muscle-type nicotinic acetylcholine receptor. The claimed compounds have common formula (I): X1-X2-X3-Pro-X4-Pro-X5 (SEQ ID NO: 54), where X1 is chosen within H, Ac—, Palm-; X2 is chosen within Trp, Tyr; X3 is chosen within Trp, Tyr; X4 is chosen within Lys, Orn, Dbu, Dpr, Arg; X5 is chosen within —OH, —NH 2 , —OCH 3 , —OC 2 H 5 , —NH—C 6 H 5 . The invention can be applied in cosmetics for smoothing mimic and age-related wrinkles |
