  Synthesis and evaluation of furoxan-based nitric oxide-releasing derivatives of tetrahydroisoquinoline as anticancer and multidrug resistance reversal agents

  摘要：

  Multidrug resistance in tumor cells poses a major obstacle to efficient chemotherapy. Several types of agents have been recognized as multidrug resistance inhibitors, among which the tetrahydroisoquinolines is the most studied. In current study 16 furoxan-based nitric oxide-releasing derivatives of tetrahydroisoquinoline were synthesized. Their cytotoxic activities and effects in reversing multidrug resistance have been evaluated. The results revealed that these compounds had moderate cytotoxic effects. Compounds 7a-f, 7h, and 7l showed higher cytotoxicities than the rest, but lower than adriamycin on K562 cell line. Compounds 7d, 7f, and 7l exhibited potent MDR reversal activities on K562/A02 cell line. The accumulation assay indicated that compounds 7d, 7f, and 7l significantly increased the intracellular accumulation of rhodamine123 in K562/A02 cells. Furthermore, these three compounds produced high concentrations of NO in K562/A02 cells. Potentially, the high concentrations of NO produced by NO donor moieties will lead to an increased cytotoxicity to K562/A02 cells. Our results suggested that compounds 7d, 7f, and 7l had anticancer effects, as well as multidrug resistance reversal effects. (C) 2011 Elsevier Ltd. All rights reserved.

  摘要：

  我们在这里描述了一系列四氢异喹啉的合成和评估，这些四氢异喹啉显示含有 GluN2C 或 GluN2D 亚基的 NMDA 受体的亚基选择性增强。Bischler-Napieralski 条件用于将无环酰胺转化为相应的含四氢异喹啉类似物的关键步骤。使用来自非洲爪蟾卵母细胞的双电极电压钳记录和加载有 Ca 2+敏感染料的哺乳动物 BHK 细胞的成像来评估化合物。最有效的类似物具有 EC 50300 nM 的值并显示对最大有效浓度的谷氨酸和甘氨酸的反应增强 2 倍以上，但对含有 GluN2A 或 GluN2B 亚基 AMPA、红藻氨酸和 GABA 或甘氨酸受体或各种不同类型的 NMDA 受体的反应没有影响其他潜在目标。这些化合物代表一类有效的 NMDA 受体小分子亚基选择性增效剂。

  Multidrug resistance in cancer is a major cause of failure in cancer chemotherapy. In search of new compounds with strong reversal activity and simple molecular structure, we have synthesized a series of compounds in which different substituents were linked to the 2-position of the 6,7-dimethoxy-1-(3,4-dimethoxybenzyl)- tetrahydroisoquinoline system. Compounds were analyzed for their cytotoxicity by MTT in K562 cell line in vitro, all of the derivatives exhibited little cytotoxic activity. In the meantime, these compounds were evaluated by MTT in K562/A02 cell line in vitro, 6e, 6h and 7c exhibited similar or more potent activities than verapamil with the IC50 values at 0.66, 0.65 and 0.96μM, and with the ratio factor of 24.13, 24.50 and 16.59, respectively.

  癌症的多药耐药性是癌症化疗失败的主要原因。为了寻找具有强逆转活性且分子结构简单的新化合物，我们合成了一系列化合物，在这些化合物中，6,7-二甲氧基-1-(3,4-二甲氧基苄基)-四氢异喹啉体系的 2 位上连接了不同的取代基。 通过 MTT 对 K562 细胞株进行体外细胞毒性分析，所有衍生物都表现出微弱的细胞毒性活性。同时，这些化合物在 K562/A02 细胞系中进行了 MTT 体外评估，6e、6h 和 7c 表现出与维拉帕米相似或更强的活性，IC50 值分别为 0.66、0.65 和 0.96μM，比值分别为 24.13、24.50 和 16.59。
