Galeterone Chemical Properties,Usage,Production

Description

Galeterone (TOK-001) is a small molecule oral drug that disrupts AR signaling by a novel triple mechanism: it potently and selectively inhibits CYP17 lyase, potently antagonizes AR and decreases AR protein levels (wild-type and mutant), leading to antitumor activity. Galeterone has shown significant anti-tumour activity with a well-tolerated safety profile in patients with CRPC in phase I and II clinical studies.

Uses

Galeterone is an androgen receptor antagonist and CYP17A1 enzyme inhibitor. It has been used in trials studying the treatment of Prostate Cancer.

Definition

ChEBI: Galeterone is a 3-hydroxy steroid. It has a role as an androgen.

Biological Activity

The cytochrome P450 (CYP) isoform CYP17 is also known as steroid 17α-hydroxylase/17,20 lyase because it catalyzes both 17α-hydroxylase and 17,20 lyase reactions in the synthesis of steroids, including androgens, estrogens, glucocorticoids, and mineralocorticoids. Galeterone is a CYP17 inhibitor (IC50 = 300 nM) that has been shown to competitively block synthetic androgen binding (EC50 = 845 nM) and to antagonize the androgen receptor in transcriptional activation assays. Galeterone can inhibit the growth of castration-resistant prostate cancer cells with an IC50 value of 2.9 μM and demonstrates synergy with everolimus or gefitinib for growth inhibition.

Mode of action

Galeterone is an orally bioavailable small-molecule androgen receptor modulator and CYP17 lyase inhibitor with potential antiandrogen activity. Galeterone exhibits three distinct mechanisms of action: 1) as an androgen receptor antagonist, 2) as a CYP17 lyase inhibitor and 3) by decreasing overall androgen receptor levels in prostate cancer tumors, all of which may result in a decrease in androgen-dependent growth signaling. Localized to the endoplasmic reticulum (ER), the cytochrome P450 enzyme CYP17 (P450C17 or CYP17A1) exhibits both 17alpha-hydroxylase and 17,20-lyase activities, and plays a key role in the steroidogenic pathway that produces progestins, mineralocorticoids, glucocorticoids, androgens, and estrogens.
