Described are ortho carboxy phenol derived acetals and compositions containing ortho carboxy phenol derived acetals which are useful for delivering biologically active compounds to cells. The acetals can be used to reversibly link up to three different molecules and have rapid hydrolysis kinetics in conditions which are present in a cell as well as in vivo. Cleavage of the acetal enhances delivery of the biologically active compound.
Carbohydrate–ferrocene conjugates were synthesized and showed that the ferrocene entity appeared to be confined to a low volume so that proton NMR spectroscopy revealed 3 to 4 signals for substituted cyclopentadienyl instead of two usually.
Substituted indazole-O-glucosides, compositions containing them, and methods of using them, for example for the treatment of diabetes and Syndrome X are disclosed.
This invention relates to substituted fused heterocyclic C-glycosides, compositions containing them, and methods of using them, for example, for the treatment or prophylaxis of diabetes and Syndrome X.
