4、mbogic Acid (Beta-Guttiferrin) is a medicinal compound derived from the gamboges resin of the tree,Garcinia hanburyi. Gambogic Acid has documented cytotoxic activity against tumor cell lines in culture, withconcentrations required for killing 50% of cells (LD50 of 1 M). The activity of Gambogic Acid

5、 against the 6human anti-apoptotic Bcl-2-family proteins is contrasted, using FPAs. Gambogic Acid displaces to variousextents FITC-BH3 peptide binding to all 6 proteins, with apparent IC50 1.47 M for Bcl-XL, 1.21 M for Bcl-2,2.02 M for Bcl-W, 0.66 M for Bcl-B, 1.06 M for Bfl-1, and 0.79 M for Mcl-1

6、1. The growth inhibitoryeffects of Gambogic Acid or Cisplatin (CDDP) on A549, NCI-H460, and NCI-H1299 cells are assessed by theMTT assay after 48h exposure. A concentration-dependent inhibition of cell growth is observed withGambogic Acid and CDDP, with IC50s of 3.560.36 and 21.883.21M for A549 cell

7、s, 4.050.51 and25.764.03M for NCI-H460 cells, and 1.120.31M and 25.214.38M for NCI-H1299 cells 2.體內(nèi)研究 To further investigate whether Gambogic Acid (Beta-Guttiferrin) synergises CDDP against tumour growth invivo, A549 tumors are implanted in SCID mice. When mice are treated with CDDP combined with Ga

8、mbogicAcid, the tumor inhibition rate is 69.3%, whereas those of mice treated with CDDP and GA alone are 57.2%and 29.0%, respectively 2.PROTOCOLCell Assay 2 The in vitro cell viability effects of Gambogic Acid, CDDP alone, or combined treatments are determined byMTT assay. The cells (2104 cells per

9、mL) are seeded into 96-well culture plates. After overnight incubation,A549 cells are treated with Gambogic Acid (0.44, 0.88, 1.75, 3.5, 7, 10.5 and 14 M); NCI-H460 cells aretreated with Gambogic Acid (0.5, 1, 2, 4, 8, 12 and 16 M); NCI-H1299 cells are treated with Gambogic Acid(0.125, 0.25, 0.5, 1,

10、 2 and 4 M). For the combined treatment in NSCLC cells, three sequences are tested:(a) Gambogic Acid followed by CDDP cells are exposed to Gambogic Acid for 48h, and then after washout ofGambogic Acid, cells are treated with CDDP for an additional 48h; (b) CDDP followed by Gambogic Acidcells are exp

11、osed to CDDP for 48h, and then after washout of CDDP, cells are treated with Gambogic Acidfor an additional 48h; and (c) concurrent treatment cells are exposed to both Gambogic Acid and ADM for 48h. The nature of the drug interaction is analysed by using the combination index (CI) 2.2/3 Master of Sm

13、y injected into the right flank of 7- to 8-week-old maleSCID mice. When the average tumor volume reach 100mm3, the mice are randomly divided into fourtreatment groups, including control (saline only, n=5), Gambogic Acid (3.0mg/kg per 2 days, intravenously;n=6), CDDP (4mg/kg per week, intravenously;

14、n=6), and sequential combination (CDDP treatment one daybefore Gambogic Acid treatment, n=6). CDDP (4mg/kg, weekly) is generally administered at doses less thanthe maximum-tolerated dose in an attempt to allow any additive effects of combination treatment withplatinum-based agents and Gambogic Acid

15、to be more easily detected. Tumor size is measured once every2 days with a calipre. Body weight is recorded once every 2 days. After 14 days, the mice are killed and thetumors are excised and stored at -80C until further analysis.MCE has not independently confirmed the accuracy of these methods. The
