Abstract
Propioxatins A and B, which have the formula: ##STR1## wherein R represents a hydrogen atom or a methyl group, can be prepared by cultivating a suitable strain of Kitasatosporia, e.g. Kitasatosporia sp. SANK 60684 (FERM-P 7581). They can be salified to give pharmaceutically acceptable salts. The compounds are active as enkephalinase B inhibitors and are thus capable of enhancing enkephalin activity in vivo.
