Abstract:

The reaction of 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl isothiocyanate 1 with 2-amino-4/6-substituted benzothiazoles 2a—2b gave glucosylthioureas(3a—3b), which then reacted with alkyl/aryl amine in the presence of HgCl2 to afford a series of new poly-acetyl guanidinoglucosides(4a—4d, 5a—5d, 6a—6d and 7a—7d). Deacetylation of glycosyl was carried in the CH3OH/CH3ONa solution. The structures of the new compounds were established on the basis of elemental analyses, IR, 1H NMR and mass spectral data and all compounds took β-configuration. The biological activities of these compounds have been evaluated. Compounds 4c, 6c, 8b and 8c showed anti-HIV-1 PR activity, compound 7c showed anti-influenza activity and compounds 5e, 7c and 7d showed inhibitory activity against angiotensin-converting enzyme(ACE) activity.

Key words: Glucopyranosyl isothiocyanate, Glucosylthiourea, Guanidinoglucoside, Biological activity
