Research Abstract

A novel metallo-glycolipid was designed and synthesized for giving a fluorescent carbohydrate probe that was potentially incorporated into a biological membrane. The metallo-glycolipid was succeeded in giving a fluorescent liposome with carbohydrates placed on a biomimetic liposomal membrane. The liposome was used for evaluateing recognition ability of carbohydrate to lectin. Specific binding events between lectin and carbohydrates on the liposomal surface was proved by the affinity evaluation with a fluorescent polarization analysis. Moreover, uptake of the metallo-glycocluster by HeLa cell was observed by fluorescent microscopy. These results suggest application of the metallo-glycolipid to a targeting agent for a cancer cell.
