NGR多肽修饰的脂质体及其抗肿瘤研究进展

Advance in studies on NGR peptide modified liposome and its anti-tumor performance

NGR多肽是一种能与肿瘤新生血管内皮细胞上的CD13受体结合的靶向肽。将NGR多肽与脂质体相连接,得到NGR多肽修饰的脂质体。通过静脉注射该脂质体,NGR多肽能与肿瘤新生血管上的CD13受体结合,将脂质体定位于肿瘤组织,使得脂质体中的药物浓集于肿瘤部位,从而提高抗肿瘤效果。该文从NGR多肽入手,对NGR多肽的定义、NGR多肽修饰的脂质体、NGR多肽修饰的脂质体抗肿瘤的优势和不足、NGR多肽修饰的脂质体的最新研究方向等进行了综述,并对NGR多肽修饰的脂质体未来的研究进行了展望。

Aspargine-glycine-arginine （NGR） -containing peptides are targeted peptides which can be integrated with CD13 re- ceptors on tumor vascular endothelial cells. NGR peptides are connected to liposomes to obtain NGR peptide-modified liposomes. By intravenous injection of these liposomes, NGR peptides can be combined with CD13 receptors on tumor vascular endothelial cells, posi- tion liposomes in tumor tissues, and concentrate drug in liposomes in tumor, so as to enhance the antitumor effect. The article starts with NGR peptides, summarizes definition of NGR, NGR peptide-modified liposomes, strengths and weaknesses of NGR peptide-modi- fied liposomes in antitumor and the latest study orientation of NGR peptide-modified liposomes, and looks into the future of studies on NGR peptide-modified liposomes.
