title: Synthesis of a targeting drug for antifibrosis of liver; a conjugate for delivering glycyrrhetin to hepatic stellate cells.
abstract: The neoglycoproteins that consist of human serum albumin (HSA) modified with mannose 6-phosphate ([M6P]x-HSA) were synthesized, and they showed high binding property to hepatic stellate cells (HSC) by immunohistochemical analysis. In addition, an increased substitution (X) of 6-phosphated mannose (M6P) was associated with an increased accumulation in HSC. So the [M6P]x-HSA might be a carrier to deliver drugs to HSC. The antifibrotic drug, glycyrrhetin, was chosen to conjugate to M6P(26)-HSA. The result suggests there were 6 approximately 7 glycyrrhetin molecules having been conjugated to the carrier. Targeting glycyrrhetin to HSC might reduce its adverse affects and increase the efficacy.
