The invention discloses a 3, 5-2-0-(4-chlorobenzene chlorobenzene)-2-deoxidising- D-red-furanoside that contains alpha body and beta body. The method includes the following steps: dissolving chlorine indicant into tetrahydrofuran, quickly adding to alcoholic solutioin, whisking and reacting, after reacting, vacuuming and steaming solvent to gain mixture of alpha body and beta body, taking separation by column chromatography to gain separated alpha body and beta body.

本发明公开了一种3、5-二-O-(4-氯苯甲酰基)-2-脱氧-D-赤-呋喃糖苷,它具有式表示的α体和式表示的β体,制备方法采用在室温下,将氯糖苷溶于四氢呋喃中,然后快速加入到醇溶液中,搅拌下进行反应;反应结束,减压蒸掉溶剂,得到白色固体,将该固体用石油醚溶解,过滤除去不溶物,再次减压蒸去溶剂,得到白色α体和β体的混合物,用柱色谱法进行分离,得到单独的α体和β体。

G/ml. After wt-p53 transfection and VCR treatment, the number of Bel-7402 cells was decreased; the cells were swollen severely with irregular projections; pyknosis, karyorrhexis and karyolysis were observed. After wt-p53 transfection, the expression of mdr1 and P-gp in Bel-7402 cells was down-regulated remarkably, and the expression of TopoⅡα was up-regulated.

形态学检查转染细胞,在VCR作用下细胞数明显减少,细胞散在不成片、细胞高度水肿、胞体不规则突起,可见核固缩、核裂解、核溶解。p53基因对Bel-7402细胞的mdr1/P-gp的表达有明显的抑制作用,对TopⅡα基因的表达有上调作用,对GSTπ、MRP基因表达没有影响。

Via the reacher on LJ-1, we know its water solubility is good,without emulsion inclination, has temperature&salt-resistant ability,when it used with Zinc dihydrogen phosphate, sodium sulfite and scale inhibitors, the corrosion inhibitor effectiveness can enhanced,when used with Thiourea the corrosion inhibitor effectiveness can decrease,so it can not used with thiourea.

通过对LJ-1缓蚀剂进行性能评价,发现本品水溶解性较好;无乳化倾向性;具有一定的抗温性和抗盐性;将它与磷酸二氢锌、亚硫酸钠和阻垢剂进行复配时,能提高缓蚀剂的缓蚀效果,说明它的配伍性良好,当与硫脲复配时,它的缓蚀效果有所降低,说明它与硫脲不能复配使用。

The results show that the dissolution of Ag was restrained by forming of a silver suboxide film on the surface under low oxidant concentration and atmospheric pressure conditions (e.g., in NH_3-O_2-H_2O system); when the concentration of oxidant was high enough (e.g., in NH_3-H_2O_2-H_2O system), the leaching process was carried out without forming of the film and the rate of dissolution of Ag was controlled by a step of mass transfer.

结果表明,在常压下氧化剂浓度低时(如在NH_3-O_2体系中),浸取反应受在Ag表面上生成的氧化物膜所阻碍;而在浓度足够高的氧化剂时(如在NH_3-H_2O_2体系中),浸取过程可在不生成氧化物膜的条件下进行,此时Ag的溶解速度受传质步骤控制。

If we cannot, at least we can appreciate the fusion of colors and the Expressionist feeling of urgency that is communicated.
