Abstract

A process for the production of new pepstatins, which act as pepsin inhibitors and having the formula; **(See formula)** where R is an n-caproyl radial in the case of "pepstatin" B, or it is an iso-caproyl radical in the case of pepstatin C or an alkyl ester thereof, with the alkyl group having 1-4 atoms carbon, characterized in that a pepstatin-producing specimen of Streptomyces testaceus ATCC No. 21469, or of Streptomyces argenteolus var. toyonaekensis ATCC No. 21469 is grown in a nutrient medium containing assimilable nitrogen and carbon sources for 3-10 days under aerobic conditions, the culture medium is extracted with n-butanol, the extract is concentrated to a syrup, precipitation is carried out By adding water to said syrup, the pepstatin derivatives thus precipitated are recovered and purified with the help of methyl esterification and later, if desired, are converted into their respective esters or alkaline salts.
