Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/5785951

Pyrrolnitrin is an antifungal antibiotic and is most active against dermatophytic fungi, especially the species of Trichophyton. Fist, physical and chemical properties of pyrrolnitrin was described by Arima et al. It is synthesized from tryptophan, and the synthesis is probably initiated by a chloroperoxidase enzyme system acting on tryptophan. The present report deals with the mechanism of action of pyrrolnitrin. Pseudomonas pyrrocinia and other Pseudomonas species produce pyrrolnitrin from tryptophan as secondary metabolite. Pyrrolnitrin inhibits fungal growth by inhibiting the respiratory electron transport system.

Pyrrolnitrin caused drastic swelling of mitochondria in isotonic solutions of alkali metal salts and of sucrose without any addition of substrate for the respiratory chain in mitochondria. The swelling induced by pyrrolnitrin was characterized by a biphasic swelling process; a very fast initial swelling and thereafter a very slow speed secondary swelling. The increase of pyrrolnitrin concentration exponentially increased the magnitude of over-all rapid swelling. Pyrrolnitrin enhance the latent ATPase activity of mitochondria at the similar range of concentrations to those needed for the induction of the swelling. The concentrations of pyrrolnitrin where mitochondrial swelling was induced were found to be far lower than those needed for the exhibition of inhibitory effect on the electron transport system of mitochondria.
