Mechanism of Action

In vitro

Miconazole induces changes in the actin cytoskeleton, indicative of increased filament stability, prior to ROS induction. Miconazole disrupts steroidogenesis in Leydig and adrenal cells by inhibiting 17alpha-hydroxylase/17,20-lyase (P450c17) enzyme activity, thus reducing the conversion of progesterone to androstenedione. Miconazole reversibly inhibits (Bu)(2)cAMP-stimulated progesterone production in a dose- and time-dependent manner in MA-10 cells without affecting total protein synthesis or P450(scc) and 3beta-hydroxysteroid dehydrogenase (3beta-HSD) enzyme expression or activity. Miconazole is known to interfere with the synthesis of fungal and bacterial lipid membranes as it restrains the synthesis of Ergosterol which results in accumulation of toxic methylated sterol intermediates in membranes and subsequently in fungal cell growth arrests. Miconazole induces actin cytoskeleton stabilization in Saccharomyces cerevisiae prior to induction of reactive oxygen species, pointing to an ancillary mode of action. Miconazole treatment releases Ca(2+) from the thapsigargin (TG)-sensitive ER pool of WEHI7.2 cells. Miconazole induces apoptosis, based on morphological and biochemical criteria, and on inhibition by the Bcl-2 oncogene. Miconazole–induced intracellular Ca(2+) changes is inhibited by overexpression of Bcl-2. Miconazole induces apoptosis in the glucocorticoid sensitive and resistant human T-cell leukemia lines, CEM-C7 and CEM-C1 respectively, in normal thymocytes and in normal lymphocytes, in addition to inducing cell death in WEHI7.2 cells.
