Kibdelins, novel glycopeptide antibiotics. I. Discovery, production, and biological evaluation.

چکیده
A new subspecies of Kibdelosporangium aridum subsp. largum (SK&F AAD-609), was isolated and shown to produce novel glycopeptides related to aridicins, but containing a homologous series of glycolipids based on N-acylglucosamine. These compounds showed improvements over the aridicins in in vitro activity and were effective in mouse protection studies against a range of Gram-positive bacteria, including methicillin resistant staphylococci. Pharmacokinetic studies indicated that they have high serum concentrations and long-acting potential. The kibdelin complex modified rumen metabolism in a manner favorable for growth promotion.

Antibiotic resistance mechanisms inform discovery: identification and characterization of a novel amycolatopsis strain producing ristocetin.
Discovering new antibiotics is a major scientific challenge, made increasingly urgent by the continued development of resistance in bacterial pathogens. A fundamental understanding of the mechanisms of bacterial antibiotic resistance will be vital for the future discovery or design of new, more effective antibiotics. We have exploited our intimate knowledge of the molecular mechanism of glycope...

Background: The use of new technologies in the field of drug discovery and development plays an important role in introducing new and effective drugs, optimizing the properties of existing drugs and, in general the development of various drug-dependent industries, as well as the general health of human, animal and plant communities. These methods provide new drugs at...
متن کاملValine influences production and complex composition of glycopeptide antibiotic A40926 in fermentations of Nonomuraea sp. ATCC 39727.
In actinomycetes the catabolism products of branched chain amino acids provide biosynthetic precursors for the formation of several lipid-containing antibiotics. We have determined in Nonomuraea sp. ATCC 39727 the effect of valine on production of glycopeptide antibiotic A40926, which is a complex of factors structurally differing in fatty acid moieties. Addition of valine to minimal medium inc...

Chloropolysporins A, B and C, as well as derivatives prepared from this group and alpha- and beta-avoparcins by enzymatic and mild acid hydrolysis, were active against Gram-positive bacteria including clinically isolated methicillin-resistant Staphylococci (MIC 0.39-6.25 micrograms/ml) and anaerobic enterobacteria (MIC 0.10-1.56 micrograms/ml). Derhamnosyl and demannosyl derivatives from both g...
