converted to glycosyl iodides and subsequently reacted with an azide source to achieve the stereoselective synthesis of beta-D-glycosyl azides after deacetylation. Low-temperature (4 degrees C) TEMPO oxidation of the monosaccharides provided the corresponding uronic acids, which were purified as the free acids. Oxidation of the lactosyl- and cellobiosyl azides resulted in diacid formation. However, 4',6'-O-benzylidene

Asialoglycoprotein receptor (ASGP-R) is a promising biological target for drug delivery into hepatoma cells. Nevertheless, there are only few examples of small-molecule conjugates of ASGP-R selective ligand equipped by a therapeutic agent for the treatment of hepatocellularcarcinoma (HCC). In the present work, we describe a convenient and versatile synthetic approach to novel mono- and multivalent

powerful combination of nativechemicalligation and click chemistry has been used to affect a one-pot synthesis of neoglycopeptides from propargyl-containing peptides using GalNAc-N3 as the glycan component. A versatile chemical toolkit for the fully convergent synthesis of neoglycoproteins using click chemistry, nativechemicalligation, and kinetically controlled ligation is thus demonstrated.

Since the asialoglycoproteinreceptor (also known as the "Ashwell-Morell receptor" or ASGPR) was discovered as the first cellular mammalian lectin, numerous drug delivery systems have been developed and several gene delivery systems associated with multivalent ligands for liver disease targeting are undergoing clinical trials. The success of these systems has facilitated the further study of new ligands

A new promising conjugate of betulinic acid with N-acetyl-d-galactosamine was synthesized by the simple reaction sequence: esterification and copper-catalyzed azide-alkyne cycloaddition. The obtained glycoderivative exhibited high activity against hepatocarcinoma cell lines in vitro, selectivity of cytotoxic action, and excellent binding to the asialoglycoprotein receptor (ASGPR) of hepatocytes. Its
通过简单的反应顺序合成了一种新的有前景的桦木酸与 N-乙酰-d-半乳糖胺的共轭物:酯化和铜催化的叠氮化物-炔环加成。获得的糖衍生物在体外对肝癌细胞系表现出高活性、细胞毒作用的选择性和与肝细胞的去唾液酸糖蛋白受体(ASGPR)的良好结合。其对 ASGPR 的亲和力是通过表面等离子体共振光谱法建立的,并通过计算机中的分子对接确认。提出了一种原始方法,通过将带有游离羧基的半草酸酯片段引入环 A 的 C(3) 位置来增强 C-28 桦木酸酯的细胞毒性。
