Preparation of n-acylcarnosine


PURPOSE: To obtain the titled compound useful as a drug, etc. in high yield, by reacting a 3-acylaminopropionic acid with a proper reagent activating carboxylic acids to give a reactive derivative of a 3-acylaminopropionic acid, reacting it with histidine under basic conditions. CONSTITUTION: Histidine is reacted with a reactive derivative of a 3-acylaminopropionic acid (with the proviso that 3-acylaminopropionic acid chloride is omitted){especially preferably a compund shown by the formula[R is alkyl, aryl, or aralkyl; X is reactive derivative group of carboxylic acid such as -OSO - 3 Y (Y is tertiary amine cation or alkali metal cation), -OPOCl 2 , etc.}in an aqueous medium under a basic conditions at about 9.0W12.0pH at ≤30°C, to give an N- acylcarnosine. USE: Having powerful inhibitory action on cerebral limbic system and useful as a drug. Its aluminum salt having improved antiulcer properties. COPYRIGHT: (C)1983,JPO&Japio
