Abiraterone

Chemical Properties

CAS No.	154229-19-3	Cat. No.	BCP01723
Name	Abiraterone
Synonyms	CB-7598;
Formula	C24H31NO	M. Wt	349.51

Biological Activity

Description	Abiraterone binds and inhibits wild-type and mutant androgen receptor (AR). Abiraterone inhibits in vitro proliferation and androgen receptor-regulated gene expression of androgen receptor-positive prostate cancer cells, which could be explained by androgen receptor antagonism in addition to inhibition of steroidogenesis. In fact, activation of mutant androgen receptor by eplerenone is inhibited by greater concentrations of Abiraterone. Abiraterone displaces ligand from both WT-AR and T877A with EC50 of 13.4 μM and 7.9 μM, respectively. Abiraterone inhibits lyase activity with an IC50 of 5.8 nM in rat testis microsomes. Abiraterone acetate significantly inhibits T secretion (?48%) and in turn increased LH concentration (192%).
