Abstract
The invention relates to the peptides of the formula: ##STR1## in which: R.sub.1 represents hydrogen or a protecting group for the amine group, such as t-butoxycarbonyl, benzyloxycarbonyl or lower alkanoyl groups; PA0 X represents beta-alanine glycine or a direct bond between R.sub.1 and the amine group; and PA0 R.sub.2 represents a group chosen from: ##STR2## corresponding to the side chains of the natural amino acid leucine, methionine and norleucine. These peptides inhibit gastric secretion.
