Mono-6-lipoyl-amido-2,3,6-O-permethyl-beta -cyclodextrin, TM beta CDLA, was synthesized in 79% isolated yield by coupling the mono-6-amino-permethyl-beta -cyclodextrin with lipoic acid in the presence of 1-(3-dimethylamino)ethyl carbodiimide. The identity of cyclodextrin-lipoic acid conjugate was confirmed by NMR spectroscopy and electrospray mass spectrometry. Chemiadsorption of TM beta CDLA on colloidal gold was shown to occur by colloid flocculation test analysis.

Abstract
Mono-6-lipoyl-amido-2,3,6-O-permethyl-beta -cyclodextrin, TM beta CDLA, was synthesized in 79% isolated yield by coupling the mono-6-amino-permethyl-beta -cyclodextrin with lipoic acid in the presence of 1-(3-dimethylamino)ethyl carbodiimide. The identity of cyclodextrin-lipoic acid conjugate was confirmed by NMR spectroscopy and electrospray mass spectrometry. Chemiadsorption of TM beta CDLA on colloidal gold was shown to occur by colloid flocculation test analysis.File in questo prodotto:
