چکیده
A detailed NMR study of the thiopeptide amythiamicin D establishes its solution conformation and the presence of a single intramolecular hydrogen bond involving NH13 and O28, and also provides the first evidence for self-association of thiopeptides in solution.

Radamycin, a novel thiopeptide produced by streptomyces sp. RSP9. II. Physico-chemical properties and structure determination.
The new cyclic peptide antibiotic, radamycin (1) and the known thiopeptide methylsulfomycin I (2) have been isolated from the fermentation broth of a Streptomyces sp. RSP9. The structure of radamycin was elucidated by NMR, LC-MS and FAB-MS and was established as a thiopeptide with oxazole and thiazole moieties, and several unusual amino acids.

Geninthiocin was isolated from the mycelium of Streptomyces sp. DD84 as a tipA promoter inducing substance. Based on various NMR studies, its structure was established as a thiopeptide with oxazole and thiazole moieties, and several unusual amino acids.
متن کاملThiopeptide Antibiotics Act on Both Host and Microbe to Deliver Double Punch on Mycobacterial Infection
Mycobacterial infection has long been one of the most serious infectious diseases throughout the world. Since the abuse of antibiotics, and for other reasons, the emergence of bacterial drug-resistance is now one of the most urgent clinical problems. Nowadays, the speed of antibiotic development is actually far more slowly than that of the bacterial drug-resistance generation. Thereby, searchin...
متن کاملCodon randomization for rapid exploration of chemical space in thiopeptide antibiotic variants.
Thiopeptide antibiotics exhibit a profound level of chemical diversity that is installed through cascades of posttranslational modifications on ribosomal peptides. Here, we present a technique to rapidly explore the chemical space of the thiopeptide GE37468 through codon randomization, yielding insights into thiopeptide maturation as well as structure and activity relationships. In this incarna...
متن کاملThiopeptide Antibiotics: Retrospective and Recent Advances
Thiopeptides, or thiazolyl peptides, are a relatively new family of antibiotics that already counts with more than one hundred different entities. Although they are mainly isolated from soil bacteria, during the last decade, new members have been isolated from marine samples. Far from being limited to their innate antibacterial activity, thiopeptides have been found to possess a wide range of b...
