effective against the human colon adenocarcinoma cells with IC50 concentrations of 7.5–20 μM. In this series, the carbotetracyclic catechol 4e (IC50 = 7.5 μM) and quinone 12 (IC50 = 8 μM) were found to be the most potent compounds having the IC50 of less than 10 μM with no cytotoxic effect on the normal cells. Downregulation of Cox-2 and survivin and cell cycle arrest eventually leading to apoptosis were
从Wieland-Miescher酮衍生物开始合成抗癌天然产物dysideanone的结构类似物。已经进行了体外研究以评估这些非天然的类萜对结肠癌的抗癌潜力。与它们的无环甲醇衍生物相比,发现合成的碳四环化合物具有更高的活性。发现非天然碳四环化合物4b-e,4h,4i和12对人结肠腺癌细胞具有高度有效的作用,其IC 50浓度为7.5–20μM。在这个系列中,四环邻苯二酚4e(IC 50 = 7.5μM )和醌12(IC 50 (= 8μM)是最有效的化合物,IC 50小于10μM,对正常细胞无细胞毒性作用。发现Cox-2和Survivin的下调以及最终导致细胞凋亡的细胞周期停滞是这些非天然类萜的抗癌作用的潜在机制。
