Abstract

NEW MATERIAL:A desacylvalylpepsdin derivative of formula I (R is carboxypropanoyl, 2-carboxybenzoyl, nicotinoyl, etc.).
EXAMPLE: N-3-Carboxypropanoyl-desacylvalylpepsidin.
USE: Useful for the prevention and remedy of various diseases due to hypersecretion, e.g. peptic ulcer or hypertension, having a powerful antipepsin action, inhibitory action on acidic protease and antirenin action.
PROCESS: Desacylvalylpepsidin of formula II is reacted with an organic carboxylic acid, e.g. succinic acid, phthalic acid or nicotinic acid, or a reactive derivative thereof, e.g. acid anhydride, to give the compound of formula I.
