6、one (CB7598) 的前藥形式。IC & Target CYP17A12體外研究 Abiraterone (Abi) acetate is an ester prodrug of the anticancer agent Abiraterone, which shows IC50 values of 15 nMand 2.5 nM for the 17,20-lyase and 17-hydroxylase (CYP17 is a bifunctional enzyme with both 17-hydroxylase and17,20-lyase activity). Abirater

7、one inhibits human 17,20-lyase and 17-hydroxylase with IC50 of 27 and 30 nMrespectively1. Significant inhibition of proliferation of the AR-positive prostate cancer cell lines LNCaP and VCaP withdoses of Abiraterone 5 M is confirmed2. Abiraterone inhibits recombinant human 3HSD1 and 3HSD2 activitywi

8、th competitive Ki values of 2.1 and 8.8 M. 10 M Abiraterone is sufficient to completely block synthesis of 5-dione and DHT in both cell lines.Treatment with Abiraterone significantly inhibited CRPC progression in the robustlygrowing subset, effectively putting a ceiling on tumor growth over 4 weeks

9、of treatment (P0.00001)3.體內(nèi)研究 Abiraterone (Abi) acetate prolongs survival in castration-resistant prostate cancer (CRPC). 3H-dehydroepiandrosterone (DHEA) depletion and 4-androstenedione (AD) accumulation are inhibited by Abirateronein LNCaP, with an IC501 M. The 0.5 mmol/kg/d Abiraterone treatment

10、dose is previously shown to yield serumconcentrations of about 0.5 to 1 M. Xenograft tumor growth in the control group is widely variable, with sometumors growing slowly and only a subset of tumors exhibiting robust growth3.PROTOCOLCell Assay 2 LNCaP and VCaP cells are seeded in 96-well plates and g

11、rown in CSS-supplemented phenol red-free or FBS-supplemented media for 7 days. Cells are treated with Abiraterone (5 M and 10 M) at 24 and 96 hours after platingand cell viability is determined on day 7 by adding CellTiter Glo and measuring luminescence2.MCE has not independently confirmed the accur

12、acy of these methods. They are for reference only.Animal Mice3Administration 3 Male NOD/SCID mice 6 to 8 weeks of age are surgically orchiectomized and implanted with a 5 mg 90-day sustainedrelease DHEA pellet to mimic CRPC with human adrenal physiology. Two days later, 7106 LAPC4 cells are injected

13、subcutaneously with Matrigel. Tumor dimensions are measured 2 to 3 times per week, and volume is calculated aslengthwidthheight0.52. Once tumors reach 300 mm3, mice are randomly assigned to vehicle or Abirateronetreatment groups. Mice in the Abiraterone group are treated with 5 mL/kg intraperitoneal

14、 injections of 0.5mmol/kg/d (0.1 mL 5% benzyl alcohol and 95% safflower oil solution) and control mice with vehicle only, once dailyfor 5 days per week over a duration of 4 weeks (n=8 mice per treatment). Statistical significance between Abirateroneand vehicle treatment groups is assessed by ANOVA b
