Safety Information
Hygromycin B Usage And Synthesis
  • Chemical PropertiesWhite to off-white lyophilized powder
  • Usesantibacterial, anthelmintic; LD50 ip (rat) 63mg/Kg
  • UsesHygromycin B, a selective antibiotic that is effective on most bacteria, fungi and higher eukaryotes, inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S ribosome
  • UsesHygromycin B is an aminoglycoside and a selective antibiotic agent for the hph gene. Hygromycin B inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S rib osome
  • UsesHygromycin B is a trisaccharide aminoglycoside with a terminal cyclitol produced by Streptomyces hygroscopicus, reported by researchers at Eli Lily in the early 1950s. Hygromycin B belongs to the destomycin family of aminoglycosides which contain a unique cyclic structure linking the terminal saccharide. Hygromycin B exhibits broad spectrum antibiotic and anthelmintic activity, and is used as a feed additive for swine and poultry. Hygromycin B inhibits polypeptide synthesis by binding peptidyl-tRNA and preventing translocation by Elongation Factor 2.
  • General DescriptionAmorphous solid or tan powder.
  • Air & Water ReactionsWater soluble.
  • Reactivity ProfileWeakly basic.
  • Fire HazardFlash point data for Hygromycin B are not available; however Hygromycin B is probably combustible.
  • Safety ProfilePoison by intraperitoneal route. Mutation data reported. When heated to decomposition it emits toxic fumes of Nox
