Lethal Effect of Benzene Nitrogen Mustard Glucoside Derivate on K562 Cells

A new synthesized benzene nitrogen mustard was converted into glycosyl donor-trichloroacetimidate that was glycosylated with p-nitrophenol（glycosyl donors） to form β-lactosyl p-nitrobenzene under the protection of acetyl in a stereoselective manner, was prepared and evaluated for its cytotoxicity towards cultured K562 cell line. Methylthiazoy tetrazolium（MTT） assay, transmission electron microscopy（TEM）, flow cytometry（FCM） and immunohistochemistry were utilized to explore the mechanisms of how the compound arrests the growth of HCT-T cells. This new synthesed benzene nitrogen mustard glucoside derivate（BNMGD） presented a lower toxicity to normal cells, but is significantly more toxic to K562 cells compared with nitrogen mustard, meanwhile it can induce the apoptosis of K562 cells. These results indicate that the new synthesized BNMGD can inhibit the growth of K562 cells and induce the apoptosis, and its cytotoxicity towards cultured K562 cell line is much more effective than that of nitrogen mustard.

葡萄糖苯氮芥衍生物的合成及抗肿瘤活性的研究

目的探讨新合成的葡萄糖苯氮芥衍生物对肝癌7721细胞的生长抑制及其诱导凋亡的作用。方法采用MTT,流式细胞术分析法。结果新合成的葡萄糖苯氮芥衍生物对正常细胞毒性较小,对7721有明显的细胞毒性,且通过流式细胞仪显示其诱导细胞凋亡。结论新合成的葡萄糖苯氮芥衍生物能明显抑制肝癌细胞的生长,诱导细胞凋亡是其抗肿瘤作用的主要机制之一。

N,N-二(2-氯乙基)-N'-乙酰基-1,4-苯胺的合成

以4-氯硝基苯及二乙醇胺为原料,K_2CO_3为缚酸剂,合成了N,N-二(2-羟基乙基)-4-硝基苯胺,在三乙胺的催化下,利用氯化亚砜将其转化为氮芥关键中间体N,N-二(2-氯乙基)-4-硝基苯胺。在强酸介质中用氯化亚锡将氮芥中间体还原为氮芥类抗肿瘤药效体N,N-二(2-氯乙基)-1,4-苯二胺,以乙酰氯为酰基化试剂,通过酰基化反应合成了芳胺氮芥衍生物N,N-二(2-氯乙基)-N'-乙酰基-1,4-苯胺,并利用元素分析、IR、~1H NMR确证了新化合物的结构。
