  Direct Stereoselective Synthesis of β-Thiomannosides

  摘要：

  A highly diastereoselective synthesis of beta-thiomannopyranosides is described in which S-phenyl 2,3-di-0-benzyl-4,6-O-benzylidene-1-deoxy-1-thia-alpha-D-mannopyranoside S-oxide is treated with triflic anhydride and 2,6-di-tert-butyl-4-methylpyridine in CH2Cl2 at -78 degrees C leading to the formation of an intermediate alpha-mannosyl triflate. Addition of primary, secondary, or tertiary thiols then leads to the beta-thiomannosides, by an S(N)2-like displacement, in good yield and with excellent stereoselectivity. Deprotection is achieved either by Birch reduction or by Zemplen deacetylation, of the acetyl protected aglycons, followed by hydrogenolysis over Pearlman's catalyst. The assignment of configuration of the beta-thiomannopyranosides is discussed in terms of the chemical shift of the mannose H5 resonance and the (1)J(CH) of the mannose anomeric carbon.

  Disclosed are a drug having renal selectivity and a drug carrier for specifically transporting a drug supported thereon to a kidney. A segment structure specifically recognizable in the kidney is utilized. More specifically, since a segment structure represented by formula (I) is kidney-oriented, introduction of a drug into a molecule having the segment structure can provide a renal targeting drug. A compound, which has the segment structure and can support a drug thereon, can be utilized as a drug carrier which can specifically transport a drug supported thereon to the kidney.         A-U-V-     (I) wherein A represents glycosyl, such as glucosyl, mannosyl, or 2-deoxy-glucosyl; U represents O, S, or NH; and V represents an aromatic hydrocarbon or a straight-chain or branched C1-18 aliphatic hydrocarbon.

  本发明涉及一种具有肾脏选择性的药物和一种药物载体，用于将支持在其上的药物专门运输到肾脏。利用在肾脏中特别可识别的片段结构。更具体地说，由式（I）表示的片段结构是以肾脏为导向的，将药物引入具有该片段结构的分子中可以提供肾脏靶向药物。具有该片段结构并能支持药物的化合物可用作药物载体，可将支持在其上的药物专门运输到肾脏。其中，A代表糖基，如葡萄糖基、甘露糖基或2-脱氧葡萄糖基；U代表O、S或NH；V代表芳香族碳氢化合物或直链或支链C1-18脂肪族碳氢化合物。

  This paper describes the synthesis, purification, and liquid-crystalline behaviour of a series of alkyl 1-thioglycopyranosides. The synthesis of these derivatives was carried out via a Lewis acid mediated coupling of the fully acetylated monosaccharide with an alkanethiol. The choice of the Lewis acid depends on the configuration of AcO-2, The carbohydrate-derived surfactants exhibit thermotropic liquid-crystalline behaviour. The alkyl 1-thioglycopyranosides form the expected smectic A phases upon heating. The clearing temperatures vary with alkyl chain length which is in accordance with the accepted model for the S-A phase of amphiphilic carbohydrate mesogens. For the alkyl 1-thiotalopyranosides, the clearing points are much lower than expected, presumably due to the formation of an intramolecular hydrogen bond in the talose moiety.
