  • Biologically pure culture of actinoplanes capable of producing antibiotic A/16686
    Patent number: 4328316
    Abstract: The present invention relates to a glycopeptide antibiotic arbitrarily designated as A/16686 antibiotic, and to its physiologically-acceptable acid addition salts. Antibiotic A/16686 free base, and its acid addition salts are antibacterial agents, especially active against grampositive microorganisms. The process for producing antibiotic A/16686 by culturing a novel strain of the actinoplanes genus, designated as Actinoplanes sp. ATCC 33076, is a further object of the present invention.
    Type: Grant

  • 2-Nitroimidazole derivatives
    Patent number: 4113953
    Abstract: 2-Nitroimidazole derivatives of the following formula: ##STR1## wherein R is benzoyl, phenylcarbamoyl or the group ##STR2## wherein R.sub.1 is C.sub.1-4 alkyl, ##STR3## in which R.sub.2 is hydrogen, halo, cyano, amino, C.sub.1-2 alkyl, or C.sub.1-3 alkoxy and X is oxygen or sulfur. These compounds have antimicrobial and amoebicidal utilities.

  • 2-Nitroimidazol derivatives
    Patent number: 3987053
    Abstract: 2-Nitroimidazole derivatives of the general formula ##SPC1##Wherein R is a lower alkyl group and Y is a member of the group consisting of --CH.sub.2 OH, --CHO, CH.sub.3 CO--, vinyl, formylvinyl, styryl, substituted iminomethyl, 2-benzimidazolyl and 5-amino-1,3,4-thiadiazol-2-yl. The term "lower alkyl" designates aliphatic groups of from 1 to 4 carbon atoms; the term "substituted iminomethyl" designates nitrogen-containing functional derivatives of the aldehydic group. The compounds have antimicrobial activity.
