  • Patent number: 4684644
    Abstract: The present invention is directed to a class of basic monocarboxyamide derivatives of actagardine. Actagardine (INN) is an antibiotic substance produced by actinoplanes strains such as Actinoplanes Sp. ATCC 31048 and Actinoplanes Sp. ATCC 31049 which are described in U.S. Pat. No. 4,022,884. Actagardine shows antimicrobial in vitro and in vivo activity against gram-positive organisms. Its complete chemical structure is not yet known but there is only information on its chemical functions and main fragments. In particular, it has been found that actagardine has two carboxylic functions and a primary amino function and can therefore be represented as follows: ##STR1## The compounds of the invention are monoamide derivatives at one of the carboxy functions of actagardine.
