生物活性

D4-abiraterone is a major metabolite of abiraterone. D4-abiraterone is an inhibitor of CYP17A1, 3b-hydroxysteroid dehydrogenase (3βHSD) and steroid-5a-reductase (SRD5A) and also an antagonist of androgen receptor.

IC50 & Target

CYP17

 

體外研究
(In Vitro)

D4-abiraterone (10 mM) 幾乎完全阻斷 D4-雄烯二酮 (AD) 轉(zhuǎn)化為 5α-雄烯二酮和其他 5α 還原雄激素。D4-abiraterone 對突變型(在 LNCaP 中表達,半數(shù)最大抑制濃度 (IC50=5.3 nM))和野生型(在 LAPC4 中表達,IC50=7.9 nM)雄激素受體 (AR) 的親和力大于 Abiraterone(IC50=418 和 >500 nM)。與 Abiraterone 相比,D4-abiraterone 明顯更好地抑制了 LNCAP、LAPC4 和 C4-2 細胞系中的 PSA、TMPRSS2 和 FKBP5 表達。D4-abiraterone 還以劑量依賴性方式抑制 AR 靶基因表達[1]

體內(nèi)研究
(In Vivo)

在阻斷 LNCaP 和 VCaP 異種移植瘤中 3β-羥基類固醇脫氫酶 (3βHSD) 將脫氫表雄酮 (DHEA) 轉(zhuǎn)化為 D4-雄烯二酮 (AD) 方面,D4-abiraterone 的效力比 Abiraterone 高出十倍。0.1 μM D4-abiraterone 相當于 1 μM Abiraterone,可在 48 小時內(nèi)阻斷 LNCaP 和 VCaP 異種移植瘤中的 AD 積累。與 Abiraterone 組相比,D4-abiraterone 組的進展明顯延遲[1]。

Kinase Assay
[1]

To test D4-abiraterone (D4A) as an inhibitor of 3βHSD, enzyme assays are performed. Briefly, incubations are prepared with recombinant human 3βHSD1 or 3βHSD2 (in yeast microsomes, 45 or 2.5 μg protein per incubation, respectively), D4-abiraterone (5 to 20 μM) or ethanol vehicle in 0.5 mL of potassium phosphate buffer (pH 7.4). After a pre-incubation at 37°C for 1 to 3 min, NAD+ (1 mM) is added, and the incubation is conducted at 37°C for 20 min. The reaction is stopped by addition of 1 mL ethyl acetate:isooctane (1:1), and the steroids are then extracted into the organic phase and dried. The steroids in the dried extracts are resolved by HPLC and quantitated by in-line scintillation counting[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Assay
[1]

Cells are cultured in serum-free medium for 48 h and then treated with the indicated concentrations of D4-abiraterone (D4A) for 30 min. Cells are washed with 1×PBS four times and 0.9% NaCl solution twice before lysis with RIPA buffer. Intracellular radioactivity is measured with a liquid scintillation counter and normalized to the protein concentration as detected with a Multilabel counter[1].

Animal Administration
[1]

Male NSG mice, 6 to 8 weeks of age are used in this study. Mice are surgically orchiectomized and implanted with a 5 mg 90-day sustained-release dehydroepiandrosterone (DHEA) pellet to mimic castration-resistant prostate cancer (CRPC) in the context of human adrenal physiology. Two days later, 107 VCaP or C4-2 cells are injected subcutaneously with matrigel. Once tumours reach 300mm3, mice are arbitrarily (but not strictly randomized) assigned to vehicle (n=9 or 10 mice for VCaP and C4-2 respectively), D4-abiraterone (D4A) (n=10 mice for both cell lines) treatment groups. D4-abiraterone (0.5 mmol per kg per day in 0.1 mL 5% benzyl alcohol and 95% safflower oil solution) is administered via 5 mL per kg intraperitoneal injection every day for up to 15 days. Control groups are administered 0.1 mL 5% benzyl alcohol and 95% safflower oil solution via intraperitoneal injection every day. Tumour volume is measured daily, and time to increase in tumour volume by 20% is determined. Mice are killed at treatment day 15 or when the tumour size is twofold greater than baseline[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
