Matlystatins, new inhibitors of typeIV collagenases for Actinomadura atramentaria. I. Taxonomy, fermentation, isolation, and physico-chemical properties of matlystatin-group compounds.

Abstract

During the course of a screening for inhibitors of typeIV collagenases, new metabolites, designated matlystatins, have been isolated from an actinomycete strain, which was identified as a strain of Actinomadura atramentaria. Matlystatins were composed of five congeners, which were separated and purified by n-butanol extraction and chromatography.
