制备方法与用途

秋水仙碱是从百合科植物秋仙的种子和球茎中提取出来的一种植物碱。其化学名为C22H25NO6·11/2H2O,是一种浅黄色粉末状物质,具有极强毒性,易溶于酒精氯仿甲醛中。它对植物细胞分裂有特殊作用:在一定浓度范围内,秋水仙碱不会破坏植物的生长和染色体复制过程,但能够抑制纺锤体和初生细胞壁的形成。当其渗透到正在分裂的细胞时,会导致染色体无法正常向两极移动,从而阻止了初级细胞壁的形成。最终造成染色体加倍而细胞未分裂的情况,生成一个含有双倍染色体的核。尽管适当浓度下的秋水仙碱对细胞不产生严重毒害,在处理后的一定时间内,细胞仍能恢复常态并继续分裂,从而形成多倍体细胞。

作为使细胞染色体加倍的理想药剂之一,秋水仙碱可以用于处理植物种子、器官或组织,特别是幼苗根和茎的生长点。通常使用的浓度范围为0.1~0.2%,但根据不同植物及具体条件,实际使用时可能需要调整这一数值。

  • Exploiting enzymatic regioselectivity: a facile methodology for the synthesis of polyhydroxylated hybrid compounds
    作者:Pietro Magrone、Francesco Cavallo、Walter Panzeri、Daniele Passarella、Sergio Riva
    DOI:10.1039/c0ob00304b
    日期:——
    Polyhydroxylated hybrid molecules have been synthesized using a protocol based on the regioselective acylation of the target compounds with activated dicarboxylic acids catalyzed by Novozym-435. The procedure implies that the mixed ester derivatives prepared and isolated from the first esterification step act as acylating agents in the second esterification step.

  • Biological effects of modified colchicines. Improved preparation of 2-demethylcolchicine, 3-demethylcolchicine, and (+)-colchicine and reassignment of the position of the double bond in dehydro-7-deacetamidocolchicines
    作者:Manfred Roesner、Hans-Georg Capraro、Arthur E. Jacobson、Louise Atwell、Arnold Brossi、Maria A. Iorio、Thomas H. Williams、Robert H. Sik、Colin F. Chignell
    DOI:10.1021/jm00135a005
    日期:1981.3
    A variety of colchicine, demecolcine, and isocolchicine derivatives were examined for their potency in the lymphocytic leukemia P388 screen in mice, for their toxicity in mice, and for their binding to microtubule protein. A qualitatively direct correlation was found between in vivo potency and toxicity; potency appeared to be less well correlated with tubulin binding. The most potent compounds were N-acylated analogues of colchicine and demecolcine. Among the monophenols, only 3-demethylcolchicine showed an appreciable effect in vitro and in vivo and was less toxic than colchicine. Improved methods were found for the preparation of 3- and 2-demethylcolchicine, which involved the use of 85% phosphoric acid and concentrated sulfuric acid, respectively. Decoupling experiments with 1H NMR proved that the double bond of dehydro-7-deacetamidocolchiceine and its derived tropolonic methyl ethers 24 and 25 was in the 5,6 position, rather than the 6,7 position formerly tentatively assigned.

  • Effect of organic cosolvents on the stability and activity of the β-1,4-galactosyltransferase from bovine colostrum
    作者:Sergio Riva、Barbara Sennino、Francesca Zambianchi、Bruno Danieli、Luigi Panza
    DOI:10.1016/s0008-6215(97)00273-5
    日期:1997.12
    The influence of various organic cosolvents on the stability and activity of the beta-1,4-galactosyltransferase from bovine colostrum (Ga1T) and of its ancillary enzyme UDP-galactose-4'-epimerase has been investigated using the glucosylated alkaloid colchicoside (1) as a model substrate. It has been found that some cosolvents, such as Me,SO and MeOH, can be used up to 20% v/v without any influence on the performance of these enzymes, while others, such as tetrahydrofuran, rapidly inactivated GalT at concentrations as low as 5% v/v. These results have been exploited for the galactosylation of the poorly water soluble coumarinic glucoside fraxin (2). (C) 1998 Elsevier Science Ltd.
