Biological Activity

Description Trilostane (WIN 24540) is an inhibitor of 3β-hydroxysteroid dehydrogenase used in the treatment of Cushing’s syndrome.
Targets
3 β-hydroxysteroid dehydrogenase [1]
In vitro Both Trilostane and 4-Hydroxy tamoxifen (OHT) affects transcription of genes involved in cell cycle regulation, cell adhesion and matrix formation, however, only 12.5% of Trilostane down-regulated genes and 9.2% of up-regulated genes are similarly regulated by OHT in MCF-7 cells.?sup>[1]
In vivo Trilostane treatment results in a significant decline in basal plasma cortisol concentrations in dogs. Trilostane treatment results in an insignificant decrease in plasma aldosterone concentration (PAC), but the median plasma renin activity (PRA) at the time the trilostane dosage is considered optimal (265 fmol/L/s, range 70-3280 fmol/L/s; n=18) is significantly higher than prior to treatment (115 fmol/L/s, range 15-1330 fmol/L/s). Trilostane affects both the hypothalamic-pituitary-adrenocortical and the renin-aldosterone axes. [2] Trilostane effectively blocks the increase in systolic blood pressure and reverses the hypertension produced by drinking 0.9% saline in the Dahlsalt-sensitive rat. Trilostane is equally effective in female and male rats. [3] Trilostane reduces clinical signs and improves endocrine test results in all cats, but insulin requirements does not change and all continued to have some signs of hypercortisolemia. [4] Trilostane results in a reduction in serum cortisol and aldosteroneconcentrations in dogs with PDH, although the decrease for serum aldosterone concentration is smaller than that for serum cortisol concentration.
