Abstract： 近年来研究发现许多肿瘤细胞表面高表达一些肽类受体,这些肽类受体与相应的配体亲和性高,能以配体-受体方式特异性结合.以小片段活性肽作为导向物形成复合物而发展的靶向药物递送系统,能够将药物定向转运到靶细胞内,显示了良好的研究价值和应用前景.如蛙皮素/胃泌素释放肽受体介导的靶向药物递送系统、生长抑素受体介导的靶向药物递送系统、十肽SynB,受体介导的靶向药物递送系统、黄体酮释放激素受体介导的靶向药物递送系统及其他肽类受体介导的靶向药物递送系统,其中短肽作为靶向基团与阿霉素、吡咯阿霉素、甲氨蝶呤、顺铂和喜树碱等结合形成高效的复合物,用于表达有相应受体的肿瘤,获得靶向治疗的研究非常有意义.
