  用于碳水化合物合成的微生物糖基转移酶：来自奈瑟氏淋球菌的 α-2,3-唾液酸转移酶

  摘要：

  来自淋病奈瑟菌的 α-2,3-唾液酸转移酶在大肠杆菌中过度生产，以利用其底物特异性和合成效用。本研究合成了几种潜在的受体底物，包括单糖和寡糖、糖脂、糖肽及其硫酸盐衍生物。还制备了一些在 C-5 位进行修饰的 CMP-唾液酸衍生物作为供体底物进行评估。发现与其他唾液酸转移酶相比，该酶表现出更广泛的受体底物特异性，尽管供体特异性非常有限。已证明该酶在代表性唾液酸糖缀合物的制备性合成中的应用。在这项工作和其他人的工作的基础上，

  Synthesis and cytostatical evaluation of cytidine- and adenosine-5′-hexadecylphosphate and their phosphonate analogs

  摘要：

  Four phospholipid conjugates containing the non-cytotoxic nucleosides cytidine and adenosine were prepared by condensation reactions, and their cytotoxic activity was tested in vitro against the human immortalized mammary epithelial cell H184 A(1)N(4), the human mammary tumor cells MaTu and MCF7 and the B lymphoblast cell line Daudi. The synthesized compounds showed considerable activity towards H184 A(1)N(4), MaTu and Daudi cells, but they were not effective against MCF7 cells. The phosphorus moiety-either monophosphate or monophosphonate-does not influence the effectiveness of the phospholipid derivatives in the case of the solid tumor cell lines and H184 A(1)N(4). The leukemic Daudi cell line is strongly sensitive towards the different types of ester as well as to the type of the nucleoside component. Adenosine-5'-hexadecylphosphate proved to be the most potent compound among the substances prepared (IC50: 9.0 mu mol). (C) 1997 Elsevier Science Ireland Ltd.

  The reaction of sialyl phosphites 1, 22a-d, 28, 39, and 45 with acyl-protected riboside 5-phosphorous acids 2a,b and 23 directly furnished, without addition of a catalyst, under phosphite/phosphate exchange the corresponding beta-configured sialyl riboside monophosphates 3a,b, 24a-d, 29, 46, and 47. The synthesis of the starting materials, formation of the products, and their treatment with sodium methanolate in methanol and subsequent hydrolysis of the sialic acid ester moiety to provide the unprotected target molecules 4a,b, 25a-d, 30, 48, and 49 is described. Investigations with alpha(2-6)-sialyl-transferase from rat Liver showed that base replacement in CMP-Neu5Ac (4a,b) is not tolerated by the enzyme but that modifications of the 5-, 8-, or g-position of the neuraminic acid residue (25a-d, 30, 48, 49) are tolerated.

  Reaction of sialyl phosphites 1 and 2 with dibenzyl phosphate and phenyl phosphate furnished without addition of a catalyst directly the corresponding sialyl phosphates 3 and 4, respectively, in good yields. Similarly, reaction of 1 with acetylated CMP 5 afforded exclusively beta-configurated acetylated CMP-Neu-5-Ac 6; which was readily transformed into natural sialyl donor CMP-Neu-5-Ac (7).
