oxaliplatin, LLC-202, is developed as a novel prodrug for liver cancer. The conjugate is obtained by using 3-NH2−cyclobutane-1,1-dicarboxylate as a linker between the oxaliplatin analogue and cholic acid moiety and cholic acid is strongly bonded to the linker via an amide bond. Pharmacokinetic experiment shows that LLC-202 is mainly distributed and accumulated in the liver after intravenous administration to
胆酸结合的奥沙利铂 LLC-202 是一种新型肝癌前药。通过使用 3-NH 2 -获得缀合物1,1-环丁烷二羧酸酯作为奥沙利铂类似物和胆酸部分之间的连接体,胆酸通过酰胺键与连接体牢固结合。药代动力学实验表明,给Sprague-Dawley大鼠静脉注射后,LLC-202主要在肝脏中分布和积累,揭示了肝脏靶向特性。与奥沙利铂相比,LLC-202比正常人肝细胞更容易被人肝癌细胞摄取。LLC-202 在治疗 C57BL/6 小鼠原发性肝细胞癌方面表现出比奥沙利铂更高的体外抗癌活性和更高的疗效。通过诱导癌细胞凋亡、抑制癌细胞增殖,可显着延长荷瘤小鼠的生存时间。此外,LLC-202 对正常人肝细胞的细胞毒性低于奥沙利铂。其对健康昆明(KM)小鼠静脉注射后的急性毒性与奥沙利铂相当。组织病理学检查表明LLC-202对小鼠的主要毒性是抑制骨髓造血细胞。结果表明,LLC-202作为一种针对肝癌的新型前药具有进一步开发的巨大潜力。
