- DOI: 10.26097/nor00247
- Family: gramicidin
- Synonym(s): Ile-gramicidin B;
- Activity: antimicrobial
- Category: peptide
- Formula: C98H141N19O17

- 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.
