Biochem/physiol Actions
Myxothiazol, an antibiotic with activity against fungi and insects, is a strong inhibitor of mitochondrial cytochrome b/c1-segment of respiratory chain. Myxothiazol binds to the quinol oxidation (Qo) site of the bc1 complex, blocking electron transfer to the Rieske iron-sulfur protein in the mitochondrial respiratory chain. Oxygen consumption blockage leads to a cytostatic effect that could be reversed. Myxothiazol, as other Epothilones, which are known for their anti tumor activity, contains a thiazole ring that is formed by the incorporation of cysteine into the polyketide backbone.
