    • The present invention relates to anticancer nanoparticles with improved target specificity to a cancer tissue and a method for manufacturing the same and, more specifically, to targeting-enhancing anticancer nanoparticles in which an anticancer agent, serum albumin as a nanoparticle support, and porphyrin-based compounds as a target-oriented material are combined by non-covalent bond and a method for manufacturing the same. Because the targeting-enhancing anticancer nanoparticles are formed of three kinds of ingredients of the anticancer agent, the serum albumin as a support, and target-oriented porphyrin by a non-covalent bond, the targeting-enhancing anticancer nanoparticles prevent toxic side effects and the reduction of anticancer drug efficacy and target specificity, which are often shown in anticancer nanoparticles. The nanoparticles are stabilized and a large amount of target-oriented materials are attached to the nanoparticles without a chemical structural change. Since an active oxygen-forming function is activated without a chemical structural change of porphyrin, cancer target specificity is enhanced when an electronic beam is irradiated. The targeting-enhancing nanoparticles maximize the delivery rate to cancer cells/targetability of an anticancer agent by combining the effects, thereby effectively treating advanced cancer as well as early stage cancer.

    • 本发明涉及对癌组织的靶特异性提高的抗癌纳米粒子及其制造方法,更具体地,涉及抗癌剂,作为纳米粒子载体的血清白蛋白和卟啉系的靶向增强抗癌纳米粒子 作为靶向材料的化合物通过非共价键组合及其制造方法。 由于靶向增强抗癌纳米颗粒由抗癌剂,作为载体的血清白蛋白和通过非共价键的靶向卟啉的三种成分形成,所以靶向增强抗癌纳米颗粒防止毒性副作用,并且 降低抗癌药物功效和靶特异性,这通常在抗癌纳米颗粒中显示。 纳米颗粒是稳定的,并且大量的靶向材料连接到纳米颗粒而没有化学结构变化。 由于在没有卟啉的化学结构变化的情况下激活活性氧形成功能,所以当照射电子束时,癌靶特异性增强。 靶向增强纳米粒子通过结合效果使癌细胞的递送率/抗癌剂的靶向性最大化,从而有效治疗晚期癌症以及早期癌症。 (参考号)(AA,BB)原卟啉血清白蛋白;(CC)紫杉醇;(DD)Cedrol
