摘要:
The novel substances nordanoxamine and desferrinordanoxamine, and desferrisalmycin A, B, C and D, as well as the known substances danoxamine and desferridanoxamine, are prepared from the antibiotics salmycin A, B, C and D, which are obtained by fermentation. These substances are used as chelating agents and pharmaceuticals.

Balhimycin, where appropriate in combination with one or more of its derivatives, is suitable for promoting production in monogastric or polygastric animals.
摘要:
The invention relates to new biologically active glycopeptides of the general formulaSacch--A--B--Rin which Sacch represents a monosaccharide residue with, where appropriate, the OH groups being partially or completely substituted,A represents the residue of a neutral L- or D-amino acid or --if B is absent--represents the residue of a neutral D-amino acid,B is absent or represents the residue of a neutral L- or D-amino acid or of an optionally .omega.-substituted bi-functional acidic or basic L- or D-amino acid, and R represents hydroxyl, (C.sub.1 -C.sub.8)-alkoxy, an amino radical which is optionally substituted by one or two identical or different radicals from the series comprising (C.sub.1 -C.sub.8)-alkyl, (C.sub.5 -C.sub.8)-cycloalkyl, (C.sub.5 -C.sub.8)-heteroalkyl or (C.sub.5 -C.sub.8)-heteroaryl, or another acid derivative. These compounds have enkephalinase-inhibiting properties and can thus be used, for example, as analgesics in human and veterinary medicine. The isolation of these compounds from Streptomyces albus ATCC 21838, and further processes for their preparation, are also described.
