Abiraterone acetate (CB-7598) is a potent steroidal cytochrome P450 17alpha-hydroxylase-17,20-lyase (CYP17) inhibitor with an IC50 at 4 nM.

Background Information

Abiraterone acetate has been seen to be a novel steroidal inhibitor of CYP17A1(C17,20 lyase), a cytoochrome P450 complex, a rate-limiting enzyme in androgen biosynthesis resulting in inhibtion of testosterone production in both the adrenals and the testes. ......by Affix Scientific
Abiraterone acetate (CB-7598) is a potent steroidal cytochrome P450 17alpha-hydroxylase-17,20-lyase (CYP17) inhibitor with an IC50 at 4 nM. Abiraterone is used in treatment of prostate cancer. IC50 value: Target: CYP17 Abiraterone, a potent suppressor of cytochrome P450 17 α-hydroxysteroid dehydrogenase-mediated androgen production, has heralded a new era in the hormonal treatment of men with metastatic CRPC. Abiraterone acetate is associated with hypokalaemia, hypertension, and fluid retention or oedema, secondary to its mechanism of action, and with cardiac adverse events and hepatotoxicity; however, in the phase III studies the incidences of the most frequently reported grade 3 or 4 adverse events of special interest were relatively low. ......by MedChemexpress Co., Ltd.
Abiraterone acetate is an FDA approved drug, and is an orally active acetate ester of the steroidal compound abiraterone with antiandrogen activity. Abiraterone acetate was approved by the U.S. Food and Drug Administration (FDA) in April 2011. Abiraterone inhibits the enzymatic activity of steroid 17alpha-monooxygenase (17alpha-hydrolase/C17,20 lyase complex), a member of the cytochrome p450 family that catalyzes the 17alpha-hydroxylation of steroid intermediates involved in testosterone synthesis. Administration of this agent may suppress testosterone production by both the testes and the adrenals to castrate-range levels. FDA Approval this drug in May 2011. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus). Shelf life: >2 years if stored properly Drug formulation: This drug may be formulated in DMSO ......by MedKoo Biosciences, Inc.
Abiraterone Acetate is an acetate salt form of Abiraterone which is a steroidal cytochrome CYP17 inhibitor with IC50 of 72 nM in a cell-free assay. ......by Selleck Chemicals LLC
