Perimycin, also known as aminomycin and fungimycin, is polyene antibiotic produced by Streptomyces coelicolor var.

All types consist of a polyketide core with a perosamine sugar moiety.

The variations occur at the end of the core opposite the perosamine moiety.

[citation needed] Polyene antibiotics in general are often toxic to humans and have poor bioavailability.

Perimycin has been shown to be an effective antifungal compound, but is not widely used in clinical settings.
