Abstract

The deacylpepsidin valylvalyl-4-amino-3-hydroxy-6-methylheptanoylalanyl-4-amino-3-hydroxy -6-methylheptanoic acid of the formula <IMAGE> is obtained by microbiological means, starting from the acylpentapeptide N-acylvalylvalyl-4-amino-3-hydroxy-6-methylheptanoylalanyl-4-amino-3-h ydroxy-6-methylheptanoic acid of the formula <IMAGE> in which R is an acyl group. The compound of the second formula is converted into the product of the first formula by contacting with bacteria of the species Bacillus pumilus or with their acellular culture preparations. The employed bacteria are specifically those of the strain Bacillus pumilus Kawaguchi EF 49-210 (ATCC No. 31132). The deacylpepsidin of the formula (I) is obtained in higher yields and greater purities than in known processes. It has high activity as a pepsin inhibitor.
