Sultriecin is the dominant analogue in a family of triene antibiotics originally thought to be sulfate esters, but recently unequivocally proven to be phosphate esters. While re-naming of the compound as ‘phostriecin’ may cause confusion with ‘fostriecin’, it is now recognised that sultriecin is a phosphate ester of fostriecin. Sultriecin displays potent antifungal and antitumour activity.
