  • Norine ID: NOR00247
  • Family: gramicidin
  • Synonym(s): Ile-gramicidin B;
  • Activity: antibiotic
  • Class: peptide
  • Formula: C98H141N19O17
  • Monoisotopic mass: 1856.0752841810001 g/mol
  • Comment: Gramicidin is a heterogeneous mixture of six antibiotic compounds divided into three catagories: Gramicidin A, B and C, all of which are obtained from the soil bacterial species Bacillus brevis and called collectively Gramicidin D. Gramicidin is active against Gram-positive organisms,except for the Gram-positive bacilli, and against certain Gram-negative organisms, such as Neisseria. It is useful in combination with tyrocidin in the local treatment of a variety of superficial infections caused by susceptible Gram-positive bacteria.
