Abstract:
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.
Abstract:
The present invention relates to diionic liquid salts of dicationic or dianionic molecules, as well as solvents comprising diionic liquids and the use of diionic liquids as the stationary phase in a gas chromatographic column.
