Trilostane

Common Name

Trilostane Description

Trilostane is only found in individuals that have used or taken this drug. It is an inhibitor of 3 beta-hydroxysteroid dehydrogenase used in the treatment of Cushings syndrome. It was withdrawn from the United States market in April 1994. [Wikipedia]Trilostane produces suppression of the adrenal cortex by inhibiting enzymatic conversion of steroids by 3-beta-hydroxysteroid dehydrogenase/delta 5,4 ketosteroid isomerase, thus blocking synthesis of adrenal steroids.

    Enzymes

    General function:
    Involved in sequence-specific DNA binding transcription factor activity
    Specific function:
    Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform beta-cx lacks ligand binding ability and has no or only very low ere binding activity resulting in the loss of ligand-dependent transactivation ability. DNA- binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual

    General function:
    Involved in 3-beta-hydroxy-delta5-steroid dehydrogenase activity
    Specific function:
    3-beta-HSD is a bifunctional enzyme, that catalyzes the oxidative conversion of Delta(5)-ene-3-beta-hydroxy steroid, and the oxidative conversion of ketosteroids. The 3-beta-HSD enzymatic system plays a crucial role in the biosynthesis of all classes of hormonal steroids. Efficiently catalyzes the transformation of pregnenolone to progesterone, 17-alpha-hydroxypregnenolone to 17-alpha-hydroxyprogesterone, DHEA to 4-androstenedione, dihydrotestosterone to 5-alpha-androstane-3 beta,17 beta-diol, dehydroepiandrosterone to androstenedione and 5-alpha-androstan-3 beta,17 beta-diol to 5-alpha-dihydrotestosterone.
