摘  要:目的获得具有抗肿瘤活性的去甲斑蝥素壳聚糖衍生物,解决去甲斑蝥素的血管刺激性及水溶性问题。方法以壳聚糖与去甲斑蝥素为起始原料,经一步反应制备去甲斑蝥素壳聚糖(norcantharidin chitosanderivative,Nor-Chi);选用小鼠肉瘤S180瘤株为模型,对去甲斑蝥素壳聚糖的抗肿瘤活性与升高白细胞的作用进行考察。结果通过IR和NMR谱确证了目标化合物的结构,产品收率为43%;低、中、高剂量去甲斑蝥素壳聚糖抑瘤率分别为32.9%、40.6%、60.8%;给药后3个剂量组的白细胞数都有显著增加,分别为9.82×106、15.4×106、15.0×106;高剂量组抗肿瘤效果与阳性对照药5-氟尿嘧啶无差异。结论去甲斑蝥素壳聚糖具有抗肿瘤活性和升高白细胞作用。Objective To prepare norcantharidin chitosan derivative(Nor-Chi) and evaluate its antitumor activity as well as its increasing leukocyte effect.Methods The target compound was synthesized by only one step with chitosan and norcantharidin as the starting materials.S180 sarcoma mice were selected to estimate its antitumor and increasing leukocyte activities.Results The structure of the target compound was confirmed by IR andNMR, with yield 43 %.The tumor inhibition rates of low, middle and high doses of Nor-Chi were 32.9 %,40.6 % and 60.8 %, respectively;and the number of leukocyte was 9.82×106,15.4×106 and 15.0×106, respectively.There was no remarkably difference between the high dose Nor-Chi and positive control 5-fluorouracil regarding antitumor effect.However, the number of leukocytes in the three tested groups increased significantly.Conclusion Norcantharidin chitosan derivative has antitumor activity and increasing leukocyte effect.
