摘要&RGD 肽是含有精氨酸- 甘氨酸- 门冬氨酸(Arg-Gly-Asp) 序列的一类短肽,能和细胞表面的整合素受体特异性结合。整合素受体,尤其是&v&3 高表达于脑胶质瘤等肿瘤细胞表面,而在成熟血管内皮细胞呈低表达。因此,在脑胶质瘤的靶向治疗和显像研究中外源性RGD 肽与肿瘤细胞表面的整合素受体的竞争性结合得到广泛研究。本文综述了RGD 肽介导的脑胶质瘤靶向治疗及显像的典型方法及近年来的研究进展。

Abstract:
RGD peptides are small peptides containing arginine-glycine-aspartic acid triple peptide motif and can bind specifically to integrin receptors on cell surface. Integrin receptors, especially &v&3, are highly expressed on tumor cell (glioma for example) surface while showing low expression on mature endothelial cells. Therefore, in the studies of targeted therapy and imaging for glioma, the competitive binding between ectogenic RGD peptides and integrin receptors on the tumor cell surface has been widely studied. In this paper, the typical methods and progress in RGD peptide-mediated targeted therapy and imaging for glioma in recent years are reviewed.

合成路线数
合成路线表述
Cilengitide is synthesized using solid-phase Merrifield-type methods by sequentially adding N-Boc-N-Me-L-Val (I), N-Boc-D-Phe (III), N-Boc-4-O-t-Bu-L-Asp (V), N-Boc-Gly (VII) and Nalpha-Fmoc-Nomega-Mtr-L-Arg (IX) in a stepwise manner to a 4-hydroxymethylphenoxymethyl-polystyrene resin (Wang type resin), yielding peptide-resin intermediates (II), (IV), (VI), (VIII) and (X), respectively. Elimination of the resin from the peptide chain with a 1:1 mixture of TFA/dichloromethane results in the linear peptide (XI), which is then deprotected at the amino-terminal group by removing the Fmoc group with a 1:1 mixture of piperidine/DMF, to give peptide (XII).
