摘要:
A novel compound named "cornexistin" has the formula (I): ##STR1## and it and the corresponding ring-opened diacid and salts thereof have herbicidal and growth regulating effects. Cornexistin can be prepared by cultivation of a microorganism of the genus Paecilomyces, e.g. Paecilomyces variotii Bainier SANK 21086.

摘要:
Novel compounds, called chloropolysporins B and C, and salts thereof have antibiotic properties and would appear to be members of the class of glycopeptide antibiotics containing chlorine. They may be produced by cultivating a suitable strain of miroorganism of the genus Micropolyspora, especially Micropolyspora sp. SANK 60983 (FERM BP-538). They may be combined with conventional pharmaceutically acceptable carriers or diluents for therapeutic use or incorporated into edible excipients, such as feed or water, for use as a growth-promoting agent, especially for farm animals.

摘要:
Macrolide antibiotics are derivatives of the compound Mycoplanecin and have the formula: ##STR1## (in which R represents a hydrogen atom or an N-(.alpha.-hydroxybutyryl)-N-methylvalyl group). The compound in which R represents an N-(.alpha.-hydroxybutyryl)-N-methylvalyl group can be prepared by reducing Mycoplanecin and the compound in which R represents a hydrogen atom can be prepared by the hydrolysis of Mycoplanecin or of the compound of formula (I) in which R represents an N-(.alpha.-hydroxybutyryl)-N-methylvalyl group.
