Omiganan is a cationic antimicrobial peptide with activity against both gram-positive and gram-negative bacteria, as well as Candida spp. isolates. This compound, serving as an analogue of indolicidin, is utilized for research purposes related to alcohol nose and acne.

Omiganan results in a statistically significantly reduction in bacterial counts. omiganan reduces the bacterial counts by 3.8 (S. aureus), 2.2 (S. epidermidis) and 2.3 (C. albicans) log 10 CFU/site. Omiganan has rapid bactericidal and fungicidal properties and significant dose-dependent activity against a broad spectrum of infected organisms[2].
