The present invention relates to a long-circulating liposome modified with c(RGD-ACP-K). The present invention pertains to the field of pharmaceutical preparations, in particular to the field of targeted pharmaceutical preparations. More specifically, the present invention relates to a long-circulating liposome, the surface of the liposome being modified with c(RGD-ACP-K), and the liposome comprising doxorubicin or a pharmaceutically acceptable salt thereof such as doxorubicin hydrochloride as an anti-cancer active agent. The long-circulating liposome can targetedly deliver the anti-cancer active agent into tumor neovascular endothelial cells and tumor cells and can prolong the circulation time of the liposome in vivo, thereby enhancing the therapeutic effect of anti-tumor medicaments.
本发明涉及一种用 c(RGD-ACP-K)修饰的长循环脂质体。本发明涉及药物制剂领域,特别是靶向药物制剂领域。更具体地说,本发明涉及一种长循环脂质体,脂质体的表面用c(RGD-ACP-K)修饰,脂质体包含作为抗癌活性剂的多柔比星或其药学上可接受的盐,如盐酸多柔比星。长循环脂质体可将抗癌活性剂靶向递送到肿瘤新生血管内皮细胞和肿瘤细胞中,延长脂质体在体内的循环时间,从而提高抗肿瘤药物的治疗效果。
