  Synthesis and anti-tumor activity of carbohydrate analogues of the tetrahydrofuran containing acetogenins

  摘要：

  The tetrahydrofuran (THF) containing annonaceous acetogenins (AAs) are attractive candidates for drug development because of their potent cytotoxicity against a wide range of tumors and their relatively simple and robust structures. Replacement of the THF segment with a sugar residue may deliver analogues with improved tumor selectivity and pharmacokinetics and are therefore attractive for drug development. As a first test to the feasibility of such structures, a set of such monosaccharide analogues was synthesized and assayed against four human tumor cell lines, cervical (HeLa), breast (MDA-MB231), T-cell leukemia (Jurkat) and prostate (PC-3). Certain analogues showed low micromolar activity that was comparable to a structurally similar, naturally occurring mono-THF acetogenin. A preliminary examination of the structure-activity profile of these carbohydrate analogues suggests that they have a similar mechanism of action as their THF congeners. (C) 2013 Elsevier Ltd.

• Synthesis of alkyl and cycloalkyl α-d-mannopyranosides and derivatives thereof and their evaluation in the mycobacterial mannosyltransferase assay

  日期：2010.7

  The synthesis of a series of alkyl (having from C6 to C20 aglycones), cyclohexyl, and cyclohexylalkyl alpha-d-mannopyranosides, 6-deoxygenated analogs, thioglycosides, and sulfones derived thereof, is reported. Here, under the in vitro assay conditions used, none of the 15 tested compounds acted as an inhibitor of the mannose transfer catalyzed by the enzymes present in mycobacterial membrane and cell

  据报道，合成了一系列烷基（具有从C 6至C 20的糖苷配基），环己基和环己基烷基α-d-甘露吡喃糖苷，6-脱氧类似物，硫代糖苷及其衍生的砜。在此，在所用的体外测定条件下，15种被测化合物均未充当分枝杆菌膜和细胞壁组分中存在的酶催化的甘露糖转移的抑制剂。在分枝杆菌甘露糖基转移酶反应中，包含较短的脂族，最多8个碳原子长的线性或环状糖苷的甘露吡喃糖苷用作受体底物。与砜相反，该硫糖苷表现出相似的行为，而后者基本上未被分枝杆菌酶所识别。6-脱氧糖苷未被酶处理，
