製品説明

特性

Abiraterone is a drug used in castration-resistant prostate cancer.

Targets

CYP17 ^[1]
(Cell-free assay)

72 nM

In Vitro
In vitro	Abiraterone shows a good complexation with the heme iron only in SM1. ^[1] Abiraterone blocks the synthesis of androgens by inhibiting CYP17A1. Abiraterone also blocks 3β-hydroxysteroid dehydrogenase (3βHSD), an enzyme that is absolutely required for the synthesis of biologically active androgens. Abiraterone inhibits conversion of DHEA to Δ⁴-androstenedione. Abiraterone inhibition of 3βHSD blocks DHT synthesis and the androgen receptor response. Abiraterone inhibits the conversion of Δ⁵-androstenediol to testosterone. ^[2] Abiraterone inhibits C_17,20-lyase, with an IC50 of 5.8 nM, in rat testis microsomes. Abiraterone significantly inhibits testosterone secretion (−48%) and in turn increases LH concentration (192%). ^[3] Abiraterone inhibits in vitro proliferation and AR-regulated gene expression of AR-positive prostate cancer cells, which could be explained by AR antagonism in addition to inhibition of steroidogenesis. ^[4]
Kinase Assay	C_17,20-lyase activity assay
Kinase Assay	Microsomes are diluted to a final protein concentration of 50 μg/mL in the reaction mixture which contains 0.25 M sucrose, 20 mM Tris-HCl (pH 7.4), 10 mM G6P and 1.2 IU/mL G6PDH. After equilibration at 37 °C for 10 minutes, the reaction is initiated by addition of βNADP to obtain a final concentration of 0.6 mM. Prior to the distribution of 600 μL of the reaction mixture in each tube, test compounds are evaporated to dryness under a stream of nitrogen and then are incubated at 37 °C for 10 minutes. After incubation with Abiraterone, 500 μL of the reaction mixture is transferred to tubes containing 1 μM of the enzyme substrate, 17OHP. After a further 10 minutes incubation, tubes are placed on ice and the reaction is stopped by addition of 0.1 ml NaOH 1N. Tubes are deep-frozen and stored at -20 °C until assayed for Δ4A levels. A Δ4A RIA is developed and automated on a microplate format in our laboratory using a specific antibody against Δ4A and instructions provided by Biogenesis. The separation of free and bound antigen is achieved with a dextran-coated charcoal suspension. After centrifugation, aliquots of the clear supernatant are counted in duplicates in a liquid scintillation counter. The Δ4A concentrations of unknown samples are determined from the standard curve. The detection limit is 0.5 ng/mL and the within and between assay coefficients of variation are 10.7 and 17.6%, respectively at an assay value of 13 ng/mL. The rate of enzymatic reaction is expressed as pmol of Δ4A formed per 10 minutes and per mg of protein. The value of maximum activity without inhibitor (control) is set at 100%. The IC50 values are calculated using non-linear analysis from the plot of enzyme activity (%) against log of inhibitor concentration.
細胞実験	細胞株	LNCaP and VCaP cells
	濃度	0 μM -10 μM
	反応時間	24 hours and 96 hours
	実験の流れ	LNCaP and VCaP cells are seeded in 96-well plates and grown in CSS-supplemented phenol red-free or FBS-supplemented media for 7 days. Cells are treated with Abiraterone at 24 hours and 96 hours after plating and cell viability is determined on day 7 by adding CellTiter Glo and measuring luminescence.

In Vivo
In Vivo	Following intraperitoneal administration in a rodent model, abiraterone was found to have rapid deacetylation. When administered as its acetate pro-drug (CB 7630), it suppressed circulating testosterone to undetectable levels and markedly decreased the weights of androgen sensitive organs. Abiraterone is well tolerated and the mean elimination half-life of abiraterone in these studies was 27.6 h (thus supporting the use of once-daily dosing)^[5]. Preclinical studies with abiraterone demonstrated reduction in androgen production downstream of CYP17 which resulted in decreased weight of the ventral prostate, testis, and seminal vesicles in mice^[6].
