  Mitochondrial targeted β-lapachone induces mitochondrial dysfunction and catastrophic vacuolization in cancer cells

  摘要：

  Mitochondria play important roles in tumor cell physiology and survival by providing energy and metabolites for proliferation and metastasis. As part of their oncogenic status, cancer cells frequently produce increased levels of mitochondrial-generated reactive oxygen species (ROS). However, extensive stimulation of ROS generation in mitochondria has been shown to be able to induce cancer cell death, and is one of the major mechanisms of action of many anticancer agents. We hypothesized that enhancing mitochondrial ROS generation through direct targeting of a ROS generator into mitochondria will exhibit tumor cell selectivity, as well as high efficacy in inducing cancer cell death. We thus synthesized a mitochondrial targeted version of beta-lapachone (XJB-Lapachone) based on our XJB mitochondrial targeting platform. We found that the mitochondrial targeted b-lapachone is more efficient in inducing apoptosis compared to unconjugated b-lapachone, and the tumor cell selectivity is maintained. XJB-Lapachone also induced extensive cellular vacuolization and autophagy at a concentration not observed with unconjugated b-lapachone. Through characterization of mitochondrial function we revealed that XJB-Lapachone is indeed more capable of stimulating ROS generation in mitochondria, which led to a dramatic mitochondrial uncoupling and autophagic degradation of mitochondria. Taken together, we have demonstrated that targeting b-lapachone accomplishes higher efficacy through inducing ROS generation directly in mitochondria, resulting in extensive mitochondrial and cellular damage. XJB-Lapachone will thus help to establish a novel platform for the design of next generation mitochondrial targeted ROS generators for cancer therapy. (C) 2015 Elsevier Ltd. All rights reserved.

  拉帕胆及其相关萘醌的制备合成

  摘要：

  通过将氢化锂加到醌在二甲基亚砜中的冷冻溶液中，原位制备2-羟基-1，4-萘醌的锂盐。当溶液解冻时，锂醌缓慢形成，然后用3，3-二甲基烯丙基溴化物烷基化。因此以40％的产率获得了拉帕胆。用间氯过氧苯甲酸处理后，将其转化为环氧化物，用三氟化硼醚化物将其环化为3-羟基-β-拉帕酮，总收率为67％。后者的酯通过使用1，1'-羰基二咪唑和DBU作为缩合剂与羧酸衍生物缩合而制备。
