General description

Chemical structure: macrolide

Application

Pimaricin is an amphoteric antibiotic from Streptomyces chattanoogensis. It is used for a variety of fungal infections, mainly topically. It is used as an ergosterol and cholesterol binding agent to study lipid bilayer dynamics, especially in fungal cells. Pimaricin is used as a fungicide in agar media. It is used to study the pleitropic regulator AdpAch and the gamma-butyrolactone regulatory system of Streptomyces chattanoogensis.

Biochem/physiol Actions

An antifungal polyene macrolide that binds specifically to ergosterol and blocks fungal growth. However, unlike nysatin and filipin, pimaricin does not change the permeability of the plasma membrane

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Recommended storage temperature: 2 - 8 °C. Light sensitive.

The complete natamycin (NTM) biosynthetic gene cluster of Streptomyces chattanoogensis was cloned and confirmed by the disruption of pathway-specific activator genes. Comparative cluster analysis with its counterpart in Streptomyces natalensis revealed different cluster architecture between these two clusters. Compared with
