AbstractThe synthesis and biological activity of oleylN-acetyl-α- and β-d-glucosaminides (1 and 2, respectively) and their thioglycosyl analogues (3 and 4, respectively) are reported. The compounds exhibited antimitotic activity on rat glioma (C6) and human lung carcinoma (A549) cell cultures in the micromolar range. Analysis of cell extracts using ultra performance liquid chromatography–mass spectrometry showed that the synthetic glycosides produce alterations in glycosphingolipid metabolism, with variable effect on the level of glucosylceramide depending on the configuration of the antimitotic used. In vivo experiments in nude mice bearing an implanted C6 glioma showed that the α-thioglycoside 3 reduced tumor volume, while the O-glycosyl derivative was inactive, highlighting the importance of using enzyme resistant glycosides.
