title: Studies on new dehydropeptidase inhibitors. I. Taxonomy, fermentation, isolation and physico-chemical properties.
abstract: WS1358A1 (FR104007) and B1 (FR104008), new potent inhibitors of renal dehydropeptidase, were isolated from the culture broth of strain No. 1358 which was identified as Streptomyces parvulus subsp. In vitro inhibitory activities (IC50 value) of WS1358A1 and B1 against porcine renal DHP were 3 and 600 nM, respectively.
