  Synthesis, CI-MS Analyses and Preliminary Biological Evaluation of a Novel Library of Hydrophobic Persulfide-Spacers α-Alkyl Glycosides

  摘要：

  We report the synthesis of novel polyether-based polyols derived from simple glycosides that bear sulfur spacers in the attempt to potentially provide new antibiotics. The CI-MS demonstrated the stepwise and successive fission of the sulfide-spacer groups; however, it does not distinguish between the alditols having different arrangement of O(CH2)(3)-S(CH2)(2)OH groups. The investigated compounds exhibited antimicrobial activities against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and antifungal activities against Candida albicans at a concentration of 1 mg / ml in DMF.

  Methods for promoting plant growth based on novel photosafening treatment regimes with glycopyranosides including glycopyranosylglycopyranosides, and aryl-a-D-glycopyranosides, and more specifically, with one or more compounds comprising terminal mannosyl-triose, optionally in the presence of light enhanced by one or more light reflecting and/or refracting members such as silicon-based substrates. Furthermore, chemical synthesis processes for the above compounds are disclosed for general application to plants. Silicate microbeads of the like are distributed over the ground or substrate in which roots of a plant are supported and planted, beneath and around a plant in a manner that light is refracted or reflected toward the phylloplane.
