  Synthesis and Cytotoxicity of Coumarin Derivatives and Nordentatin

  摘要：

  合成了Nordentatin和10种香豆素衍生物并对其细胞毒性进行了评估。化合物6、7、9和13对NCI-H187细胞系表现出细胞毒性，IC50值在3-7 μg/mL范围内。在合成的香豆素中，化合物4和13对KB细胞系显示出细胞毒性，分别为3.94和6.44 μg/mL的IC50值。幸运的是，由于香豆素4和7对正常细胞表现出微弱的活性或无活性，它们可能成为开发抗癌药物的新型先导化合物之一。

  Seselin and alloxanthoxyletin, naturally occurring pyranocoumarins, were recently isolated from a number of plant sources, such as family of Rutaceae. It was previously reported that their natural and synthetic derivatives show cytotoxic and antitumor activity. In the present study new series of O-aminoalkyl substituted alloxanthoxyletins and seselins were synthesized and evaluated for their anticancer toxicity. Microwave assisted synthesis was used, and the structures of the compounds were confirmed by H-1 NMR, C-13 NMR and MS spectroscopic data. The molecular and crystal structure of 3a was analyzed by single crystal X-ray diffraction. Alloxanthoxyletin derivatives 2a, 2b, and 2d showed the highest cytotoxic potential against HTB-140 cells with IC50 of 2.48, 2.80 and 2.98 mu M, respectively. In vitro drug sensitivity testing in HaCaT, A549 and HTB-140 cells were also performed. Tumor cells showed a higher sensitivity to tested compounds than normal cells. Compounds 2a, 2b and 2d inhibited cell migration and exerted stronger effect on A549 and HTB-140 cells than on HaCaT cells. In order to explain the basic mechanism of cell death induction we have investigated the effect of derivatives 2a, 2b and 2d on early and late apoptosis using annexin V-FITC/7-AAD flow cytometry analysis. Derivatives 2a and 2b were much more potent inducers of early apoptosis in HTB-140 cells compared to HaCaT and A549 cells.

  A new efficient synthetic approach to the natural coumarins 5-hydroxyseselin (5), 5-methoxyseselin (3), and (+/-) cis-grandmarin (9) is described as well as the synthesis of some new derivatives in the 5-methoxyseselin series (10-15). The natural coumarins 7-hydroxyalloxanthyletin (6), alloxanthoxyletin (8), and dipetalolactone (7) have also been obtained as secondary products. The type of fusion of the pyrano ring in all cases has been established by 2D NMR spectroscopy. The compounds have been studied for their in vitro antibacterial activity, which has been compared with that of some previously synthesized seselin derivatives. The most active compounds were 3, 7, 8, 11, and 14. Some structure-activity relationships are discussed.

  Nordentatin and 10 coumarin derivatives were synthesized and evaluated for cytotoxicity. Compounds 6, 7, 9 and 13 showed cytotoxicity against the NCI-H187 cell line with IC50 value ranging of 3-7 μg/mL. Among synthesized coumarins, compounds 4 and 13 demonstrated cytotoxicity against the KB cell line with IC50 values of 3.94 and 6.44 μg/mL, respectively. Fortunately, coumarins 4 and 7 may be one of the new lead compounds for the development of anticancer agents due to reason that they showed weak and inactive against normal cells.
