Abstract

Azole fungicides are widely used in agriculture and in human mycosis. Their antifungal activity is based on their ability to inhibit CYP51, a key enzyme in the formation of fungal wall. Several azole fungicides tested in laboratory animals have been found to possess a common teratogenic potential to induce facial, axial skeleton, and limb defects. The mechanism of the teratogenic effect has been hypothesized to be related to the capability of these substances to alter embryonic retinoic acid catabolism. Although a number of human epidemiological studies were unable to demonstrate a definite relationship between azole exposure during pregnancy and birth defects, some case reports indicate a possible teratogenic effect of high doses of azoles in humans. Because of their common mechanism of action, azole fungicides should be regarded with caution for use in pregnant women.
