Streptomyces luteosporeus |
| Synonyms | Thiolutin, Farcinicin,
Propiopyvothine, Acetopyrrothine Comment: some sources
erroneously specify "aureothricin" as a synonym of Thiolutin. Aureothricin
is an antibiotic very similar to Thiolutin, and is created as a
by-product during the Thiolutin fermentation. |
| Description: | Thiolutin is a
sulfur-containing antibiotic, which is a potent inhibitor of bacterial and
yeast RNA polymerases. It was found to inhibit in vitro RNA synthesis
directed by all three yeast RNA polymerases (I, II, and III). Thiolutin
is also an inhibitor of mannan and glucan formation in Saccharomyces
cerevisiae and used for the analysis of mRNA stability. Studies have
shown that thiolutin inhibits adhesion of human umbilical vein endothelial
cells (HUVECs) to vitronectin and thus suppresses tumor cell-induced
angiogenesis in vivo. |
