  Anticancer effects of O-aminoalkyl derivatives of alloxanthoxyletin and seselin

  摘要：

  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.
