摘要	Twenty compounds from Garcinia oblongifolia were screened for proapoptotic activity using FRET-based HeLa-C3 sensor cells. Among them, oblongifolins F and G (1 and 2), 1,3,5-trihydroxy-13,13-dimethyl-2H-pyran[7,6-b]xanthone (3), nigrolineaxanthone T (4), and garcicowin B (5) showed significant proapoptotic activity at a concentration of 10 mu M. Bioassessments were then performed to evaluate the potential of these compounds for therapeutic application. All five compounds showed significant cytotoxicity and caspase-3-activating ability in cervical cancer He La cells, with compounds 1 and 2 having the highest potencies. All five compounds specifically induced caspase-dependent apoptosis, which could be prevented by the pan-caspase inhibitor zVAD-fmk. In particular, 3 induced apoptosis through mitotic arrest. Compounds 1-5 displayed similar IC50 values (3.9-16.5 mu M) against the three cancer cell lines He La, MDA-MB-435, and HepG2. In addition, compounds 1, 2, and 4 exhibited similar and potent IC50 values (2.4-5.1 mu M) against several breast and colon cancer cell lines, including those overexpressing either HER2 or P-glycoprotein. HER2 and P-glycoprotein are known factors that confer resistance to anticancer drugs in cancer cells. This is the first study on the cytotoxicity, caspase-3-activing ability, and specificity of proapoptotic compounds isolated from G. oblongifolia in He La cells. The potential application of these compounds against HER2- or P-glycoprotein-overexpressing cancer cells was investigated.
