  Thermotropic and lyotropic properties of long chain alkyl glycopyranosides

  摘要：

  As part of a series of papers, the influence of carbohydrate headgroups and aliphatic chains on the mesogenic properties of glycolipids was investigated. Alkyl glycosides with different types of aliphatic chains were synthesised. Neutral glycolipids were oxidized to their uronic acid derivatives, using the well established TEMPO-oxidation. For comparison a 6-deoxy-6-amino alkylglucopyranoside was synthesised. In addition, the thermotropic and lyotropic phase behaviour of the synthesised compounds were investigated. The thermotropism was characterised by polarising microscopy, the lyotropism by the contact preparation method. (C) 2003 Elsevier Ireland Ltd. All rights reserved.

  as well as for antimicrobial potential on 12 bacterial and yeast strains. The most potent compounds were found to be tetradecyl and hexadecyl β-d-galactopyranosides (18, 19), which showed the best cytotoxicity and therapeutic index against CCRF-CEM cancer cell line. Similar cytotoxic activity showed hexadecyl α-d-mannopyranoside (5) but it also inhibited non-tumor cell lines. Because these two galactosides

  研究了一系列衍生自d-甘露糖，d-葡萄糖和d-半乳糖的，具有C10-C16糖苷配基的19种合成烷基和硫代烷基糖苷对7种人类癌症和2种非肿瘤细胞系的细胞毒活性以及抗菌潜力在12种细菌和酵母菌株上。发现最有效的化合物是十四烷基和十六烷基β-d-吡喃半乳糖苷（18、19），显示出对CCRF-CEM癌细胞系最佳的细胞毒性和治疗指数。相似的细胞毒活性显示十六烷基α-d-甘露吡喃糖苷（5），但它也抑制了非肿瘤细胞系。因为这两个半乳糖苷（18、19）对所有测试的细菌和酵母菌株均无活性，所以它们可能是真核细胞的靶标特异性靶标。另一方面，具有十四烷基（11）和十六烷基（12）糖苷配基的β-D-吡喃葡萄糖苷仅抑制革兰氏阳性菌粪肠球菌。从POPC模型膜上的SAXS实验推导，所研究的苷在高浓度下诱导脂质双层厚度和侧向相分离的变化。通常，葡糖苷和半乳糖苷表现出更具体的性质。具有较长糖苷配基的化合物显示出高细胞毒性，
