摘要:紫杉醇是从天然植物红豆杉属树皮中提取的单体双萜类化合物,具有良好的抗癌活性,广泛用于乳腺癌、卵巢癌、肺癌等多种癌症的治疗,被列为乳腺癌和卵巢癌的一线化疗药物。但与其他化疗药类似,耐药性是限制紫杉醇临床应用的一个主要原因。以姜黄素为代表的低毒高效中药单体成为逆转紫杉醇耐药性的研究热点。兹以姜黄素与紫杉醇用药间协同性研究进行综述,以期为临床寻找化疗辅助药物提供参考。

Abstract: Paclitaxel is a kind of monomer diterpene compound extracted from the taxus chinensis, which has good anti-cancer activity. It is widely used in the treatment of breast cancer, ovarian cancer, lung cancer and other cancers. It also has been listed as the first-line chemotherapy medicine on breast cancer and ovarian cancer. However, the drug resistance is the main obstacle to clinical application similar to other kinds of chemotherapy medicine. The low toxicity and high efficient traditional medicine monomer, represented by curcumin, has become the research focus on reversing paclitaxel resistance. This article summarized the research on synergy between curcumin and paclitaxel, with a purpose to provide references for finding clinical assistant chemotherapeutic medicine.

紫杉醇抗肿瘤活性发现于20世纪70年代,临床应用已超过20年[1]。其主要作用机制是能使快速分裂的肿瘤细胞在有丝分裂阶段被牢牢固定,抑制微管解聚。微管的破坏导致肿瘤细胞阻滞在G2-M期,并形成异常的有丝分裂纺锤体,从而阻断肿瘤细胞复制,最终发挥其抗肿瘤的作用[2]。然而,化疗耐药性的出现,使紫杉醇临床应用受到限制。目前,克服紫杉醇耐药、增强肿瘤细胞对紫杉醇的敏感性已成为紫杉醇用药新的发展战略。姜黄素是从姜黄、郁金、莪术、石菖蒲等植物根茎中提取的一种酚类衍生物,可通过对核因子κB(NF-κB)、过氧化物酶体增殖物激活受体C(PPARC)、腺苷酸活化蛋白激酶(Adenosine 5'-monophosphate-activated protein kinase,AMPK)和蛋白激酶B(AKT)等多个细胞信号分子的作用而抗血管生成,促肿瘤细胞凋亡,抑制癌细胞的侵袭和转移[3-6]。近几年研究发现,姜黄素能显著提高细胞对紫杉醇敏感性。……
