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

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)2OH 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.
