designed and synthesized a water‐soluble CPT‐conjugated molecular transporter that successfully and rapidly delivered CPT into cells. The conjugate had affinity toward mitochondria inside cells and it was distributed mainly to kidney, lung, and spleen. MTT assay confirmed that the CPP‐conjugate decreased cell viability of colon cancer cell lines to a much greater extent than the parent drug. This novel
喜树碱(CPT)及其衍生物是唯一针对DNA拓扑异构酶I的酶活性的化学类别,该酶活性涉及DNA损伤和随后的细胞凋亡。尽管CPT具有许多优点,但由于其极差的溶解度,多个外排泵的耐药性,半衰期短和生物利用度差等原因,其使用受到了限制。为了克服这些局限性,我们设计并合成了一种水溶性CPT偶联分子转运蛋白,该分子转运蛋白可将CPT成功快速地传递到细胞中。该缀合物对细胞内部的线粒体具有亲和力,并且主要分布于肾脏,肺和脾脏。MTT分析证实,CPP偶联物比结肠癌药物可大大降低结肠癌细胞系的细胞活力。体内应用,特别是用于结肠癌的治疗。
