Compounds having the general formula (I): wherein X is S, Se or NH, and stereoisomers thereof, and de-O-sulfonated analogues of all of the foregoing, but excluding naturally occurring kotalanol and de-O-sulfonated kotalanol, and methods for synthesizing same. The compounds are useful as glycosidase inhibitors, and may be used in the treatment of diabetes. The synthetic compounds may also be used as standards in the calibration or grading of natural or herbal remedies produced from natural sources of glycosidase inhibitors such as kotalanol.

Salacinol and ponkoranol homologues, derivatives thereof and methods of synthesizing and using said homologies and derivatives. The derivatives include stereoisomers, de-O-sulfonated compounds and congeners of the naturally occurring homologues. Some of the derivatives exhibit enhanced glucosidase inhibitory bioactivity in comparison to the naturally occurring compounds which have been isolated from
Salacia reticulata.
