Amicetin-A Usage And Synthesis

Enzyme inhibitor

These pyrimidine-containing glycoside antibiotic (FWAmicetin-A = 617.69 g/mol (free base); CAS 17650-86-1; FWAmicetin-B = 532.59 g/mol (free base)) from Streptomyces vinaceus-drappus and S. fasciculatus inhibits protein biosynthesis, exerting its bacteriostatic most potently on Grampositive bacteria. Amicetin B, also called plicacetin, was isolated from Streptomyces plicatus and has the identical structure minus the amethylseryl residue. It is weaker in action compared to amicetin A. Target(s): peptidyltransferase; peptidyl-tRNA hydrolase, or aminoacyl-tRNA hydrolase; ribonuclease P; protein biosynthesis.
