  H-Lys-Lys-OH 、 p-nitrophenyl 3-(2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranosyl)propionate 在 三乙胺 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 以80%的产率得到N2-[N2,N6-bis[3-[(2,3,4,6-tetra-O-acetyl-α-D-mannopyranosyl)thio]propionyl]-L-lysyl]-N6-[3-[(2,3,4,6-tetra-O-acetyl-α-D-mannopyranosyl)thio]propionyl]-L-lysine

  Cell-specific ligands for selective drug delivery to tissues and organs

  摘要：

  Various numbers of D-mannose residues have been attached via spacer arms to lysine, dilysine, and oligolysine backbones. These D-mannosyl peptide analogues were found to be potent competitive inhibitors of the uptake of 125I-labeled D-mannose-bovine serum albumin conjugate by rat alveolar macrophages. The inhibitory potency of these synthetic ligands increased with increasing number of carbohydrate moieties. The chirality of the peptide backbone did not appear to play a major role in binding, whereas variations of the length and linkage of the spacer arm notably affected the inhibitory activities. The saccharide specificity of the macrophage receptor was demonstrated by the inactivity of the corresponding D-galactosyl peptide analogues. The L-fucosyl peptide derivative was only weakly active. The trimannosyldilysine ligand (KI = 3.9 microM) and its analogues are potentially useful in selective delivery of therapeutic agents to macrophages.
