Novel macrolactins as antibiotic lactones from a marine bacterium.
نویسندگان
چکیده
Seven new macrolactins (named G~M) and known macrolactins A and F were isolated from a culture broth of Bacillus sp. PP19-H3. The strain had been isolated from the macroalga, Schizymenia dubyi. Macrolactin A, which was 24-membered lactone, had previously been reported to show antibacterial, cytotoxic and antiviral activities. The new macrolactins include 22-membered ring or dicyclic lactone in addition to geometric isomers of known macrolactins A and F. The antibacterial activities of all the macrolactins examined in this study were relatively weak.

Algicidal lactones from the marine Roseobacter clade bacterium Ruegeria pomeroyi
Volatiles released by the marine Roseobacter clade bacterium Rugeria pomeroyi were collected by use of a closed-loop stripping headspace apparatus (CLSA) and analysed by GC-MS. Several lactones were found for which structural proposals were derived from their mass spectra and unambiguously verified by the synthesis of reference compounds. An enantioselective synthesis of two exemplary lactones ...
متن کاملAcyl-homoserine lactone degrading marine bacteria: Do they exist?
Acyl-homoserine lactones (acyl-HSL) are small molecules that are used in density dependent regulation in some bacteria. These molecules freely diffuse from the cell into the outside environment. Hence, it may be advantageous for other bacteria to utilize these molecules as a carbon source. The aim of this study is to look for acyl-HSL-utilizing bacteria in the marine environment. One strain, a ...

Bacteriocins are proteinaceous antibacterial compounds that exhibit bactericidal activity against species closely related to the producer strain. The aim of this research was to investigate the production of bacteriocin by Bacillus spp. isolated from intestinal bacterial flora of the Caspian Frisian Roach (Rutilus frisii kutum). A bacteriocin produced by the bacterium Bacillus cereus strain RF ...
متن کاملStereoselective synthesis of marine antibiotic (-)-malyngolide and its stereoisomers.
A convenient synthetic method for the marine antibiotic (-)-malyngolide and its stereoisomers was accomplished from a chiral alpha-alkoxyketone (4), which was readily available as a chiron. Chiral quaternary carbon synthons (5a) and (5b) as the key intermediates were constructed by the chelation controlled addition of Grignard reagent to 4. The diastereomeric mixture of 5a and 5b was readily tr...
