摘要:
The invention relates to an antibiotic substances of microbial origin, arbitrarily denominated antibiotic GE 81112 factor A, factor B1 and factor B, , which is produced by fermentation of Streptomyces sp. DSMZ 14386, the pharmaceutically acceptable salts and compositions thereof, and their use as an antibacterial agent having inhibitory activity versus susceptible microbes.
摘要:
The invention provides methods and compositions for treatment of bacterial infections. Methods of the invention include administration of dalbavancin formulations for treatment of a bacterial infection, in particular a Gram-positive bacterial infection of skin and soft tissue. Dosing regimes include once weekly administration of dalbavancin, which often remains at therapeutic levels in the bloodstream for at least one week, providing prolonged therapeutic action against a bacterial infection.
摘要:
Novel N-hydroxyamide derivatives are disclosed. These N-hydroxyamide derivatives inhibit UPD-3O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase, an enzyme present in gram negative bacteria and are therefore useful as antimicrobials and antibiotics. Methods of synthesis and of use of the compounds are also disclosed.
摘要:
The present invention relates to the field of antibiotics, and more specifically to the isolation of nucleic acid molecules that code for the biosynthetic pathway of the glycopeptide antibiotic teicoplanin. Disclosed are the functions of the gene products involved in teicoplanin production. The present invention provides novel biosynthetic genes that code for teicoplanin production, the encoded polypeptides, the recombinant vectors comprising the nucleic acid sequences that encode said polypeptides, the host cells transformed,with said vectors and methods for producing glycopeptide antibiotics using said transformed host cells, including methods for producing teicoplanin, a precursor thereof, a derivative thereof or a modified glycopeptide different from teicoplanin or a precursor thereof.

摘要:
The invention regards a process for the production of ramoplanin-like derivatives of formula (I): RAMO-NC-CO-R (I), wherein the radical R represents a hydrocarbon radical and the portion RAMO-NH- represents deacylated ramoplanin, any of its factors or ramoplanose. The compound of Formula (I) are obtained by reacting a carboxylic acid R-COOH with deacylated ramoplanin, any of its factors or ramoplanose protected on the ornitine amino groups. New compounds wherein the hydrocarbon radical R is different from those characaterizing the ramoplanin and ramoplanose natural products and their tetrahydro-derivatives are calimed. The new compounds have the same or better antinfective activity, lower haemolytic effect and better tolerability profile than ramoplanin.
