To targeted overcome the multidrug resistance (MDR) and metastasis of liver tumors, we proposed to develop a palladium (Pd) agent based on a specific residue of human serum albumin (HSA) for multiacting on tumor cell and other components in the tumor microenvironment. To this end, a series of Pd(II) 2-acetylpyridine thiosemicarbazone compounds were optimized to obtain a Pd(II) compound (5b) with significant cytotoxicity against HepG2/ADM cells. Subsequently, we constructed a HSA-5b complex delivery system and revealed the structural mechanism of HSA delivering 5b. Importantly, 5b/HSA-5b effectively inhibited the growth and metastasis of multidrug resistant liver tumors, and HSA enhanced the targeting ability of 5b and reduced its side effects in vivo. Furthermore, we confirmed the mechanisms of 5b/HSA-5b integrating to overcome MDR and metastasis of liver tumors: multiacting on cancer cell, activating immune response, and inactivating cancer-associated fibroblasts.

开发钯 (II) 试剂,通过靶向作用于肿瘤细胞、灭活癌症相关成纤维细胞和激活免疫反应来克服肝肿瘤的多药耐药和转移
为了靶向克服肝肿瘤的多药耐药 (MDR) 和转移,我们建议开发一种基于人血清白蛋白 (HSA) 特异性残基的钯 (Pd) 试剂,用于对肿瘤细胞和肿瘤微环境中的其他成分产生多效作用。为此,优化了一系列 Pd(II) 2-乙酰吡啶硫代氨基脲化合物,以获得对 HepG2/ADM 细胞具有显着细胞毒性的 Pd(II) 化合物 (5b)。随后,我们构建了 HSA-5b 复合递送系统,并揭示了 HSA 递送 5b 的结构机制。重要的是,5b/HSA-5b 有效抑制了耐多药肝肿瘤的生长和转移,HSA 增强了 5b 的靶向能力,降低了其体内副作用。此外,我们证实了 5b/HSA-5b 整合克服 MDR 和肝肿瘤转移的机制:多作用癌细胞、激活免疫反应和灭活癌症相关成纤维细胞。
