The present invention provides convergent processes for preparing (−)-beta-elemene, (−)-beta-elemenal, (−)-beta-elemenol, and (−)-beta-elemene fluoride and analogues thereof. Also provided are intermediates useful for preparing (−)-beta-elemene. The present invention further provides novel compositions based on analogues of (−)-beta-elemene, (−)-beta-elemenal, (−)-beta-elemenol, (−)-beta-elemene fluoride and methods for the treatment of cancer, such as brain tumor, lung cancer, breast cancer, prostate cancer, ovarian cancer, colorectal cancer, gastric intestional cancer, and stomach cancer. The inventors propose a combination therapy using 1) one or more of the following anti-cancer agents: including, but not limited to, Cisplatin, 5-FU, Taxol, Taxol derivatives, and any anti-cancer agent, and 2) one or more of the following (−)-beta-elemene and its analogs, including (−)-beta-elemene, (−)-beta-elemenal, (−)-beta-elemenol, (−)-beta-elemene fluoride, and their analogs, and (−)-beta-elemene's intermediate in its chemical synthesis, for the treatment of cancer, especially for the treatment of brain tumor, lung cancer, ovarian cancer, bladder cancer, cervical cancer, colon cancer, breast cancer, and prostate cancer.
本发明提供了制备(−)-β-电子烯、(−)-β-电子烯醛、(−)-β-电子烯醇、(−)-β-电子烯氟化物及其类似物的收敛过程。还提供了用于制备(−)-β-电子烯的中间体。本发明进一步提供了基于(−)-β-电子烯、(−)-β-电子烯醛、(−)-β-电子烯醇、(−)-β-电子烯氟化物的类似物的新型组合物,以及用于治疗癌症,如脑肿瘤、肺癌、乳腺癌、前列腺癌、卵巢癌、结直肠癌、胃肠道癌和胃癌的方法。发明人提出了一种组合疗法,使用1)以下一种或多种抗癌药物:包括但不限于顺铂、5-FU、紫杉醇、紫杉醇衍生物和任何抗癌药物;以及2)以下一种或多种(−)-β-电子烯及其类似物,包括(−)-β-电子烯、(−)-β-电子烯醛、(−)-β-电子烯醇、(−)-β-电子烯氟化物及其类似物,以及(−)-β-电子烯在其化学合成中的中间体,用于治疗癌症,特别是用于治疗脑肿瘤、肺癌、卵巢癌、膀胱癌、宫颈癌、结肠癌、乳腺癌和前列腺癌。
