已證實(shí) Abiraterone 劑量 ≥5 μM 可顯著抑制 AR 陽(yáng)性前列腺癌細(xì)胞系 LNCaP 和 VCaP 的增殖[2]。Abiraterone 對(duì) 17,20-裂解酶和 17α-羥化酶的 IC50 值分別為 15 nM 和 2.5 nM(CYP17 是一種具有 17α-羥化酶和 17,20-裂解酶活性的雙功能酶)。Abiraterone 抑制人類(lèi) 17,20-裂解酶和 17α-羥化酶的 IC50 值分別為 27 和 30 nM[3]。Abiraterone 抑制重組人類(lèi) 3βHSD1 和 3βHSD2 活性,競(jìng)爭(zhēng)性 Ki 值分別為 2.1 和 8.8 μM。 10 μM Abiraterone 足以完全阻斷兩種細(xì)胞系中 5α-二酮和 DHT 的合成。使用 abi 治療可顯著抑制強(qiáng)勁增長(zhǎng)亞群中的 CRPC 進(jìn)展,有效地在 4 周的治療中限制腫瘤生長(zhǎng) (P<0.00001)。Abiraterone 可抑制 LNCaP 中的 [3H]-脫氫表雄酮 (DHEA) 耗竭和 Δ4-雄烯二酮 (AD) 積累,IC50 值 <1 μM[4]

Cell Assay
[2]

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 (5 μM and 10 μM) at 24 and 96 hours after plating and cell viability is determined on day 7 by adding CellTiter Glo and measuring luminescence[2].

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

Animal Administration
[4][5]

Mice[4]
Male NOD/SCID mice 6 to 8 weeks of age are surgically orchiectomized and implanted with a 5 mg 90-day sustained release DHEA pellet to mimic CRPC with human adrenal physiology. Two days later, 7×106 LAPC4 cells are injected subcutaneously with Matrigel. Tumor dimensions are measured 2 to 3 times per week, and volume is calculated as length×width×height×0.52. Once tumors reach 300 mm3, mice are randomly assigned to vehicle or Abiraterone treatment groups. Mice in the Abiraterone group are treated with 5 mL/kg intraperitoneal injections of 0.5 mmol/kg/d (0.1 mL 5% benzyl alcohol and 95% safflower oil solution) and control mice with vehicle only, once daily for 5 days per week over a duration of 4 weeks (n=8 mice per treatment). Statistical significance between Abiraterone and vehicle treatment groups is assessed by ANOVA based on a mixed-effect model.
Rats[5]
Male Sprague-Dawley rats (n=8, 240-260 g) are used. Blood samples (450 μL) are obtained following an i.v. 5 mg/kg dose of ART into polypropylene tubes containing Na2-EDTA solution as an anticoagulant and at pre-dose, 0.12, 0.25, 0.5, 1, 2, 4, 6, 8 and 24 h (a sparse sampling protocol is adopted during blood collection and at each time point blood is collected from four animals). Plasma is harvested by centrifuging the blood using a Biofuge at 1760g for 5 min and stored frozen at -80±10°C until analysis.

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.
