integrity and mitochondrial function. We found that none of the synthesized compounds improved CDDP activity against MCF7 cell cultures; however, TSC2 was effective in enhancing the cytotoxicity of CDDP against MDA-MB231 and A549 cancer cell cultures. We demonstrated that the cytotoxic effect is related to the TSC2 capacity to induce disruption in the cytoskeleton network and to decrease mitochondrial function
顺式二甲基二氯铂(II)(CDDP)被称为顺铂,已被广泛用于治疗乳腺癌(它是女性中最常见的癌症)和肺癌(导致世界范围内死亡的主要癌症)。新型化合物(例如噻唑衍生物)已显示出抗增殖活性,表明它们可用于抗癌治疗。在本文中,我们合成了两种新型的硫代半脲酮和一种醛与CDDP结合,以增强针对ER阳性乳腺癌MCF7癌细胞,三阴性/基底B乳腺癌细胞(MDA-MB231)和肺腺癌(A549)人细胞的功效。我们合成了2,3,5,6-四氟-4-(2-巯基乙硫醇基)苯甲醛(ALD),5-[(2,3,5,6-四氟-4-(三氟甲基)苯基)硫代] -2-呋喃硫代半碳酸钠(TSC1)和5-[(4-(三氟甲基)苯基)硫代] -2-呋喃硫代半脲(TSC2),可单独或组合使用用亚毒性CDDP浓度评估细胞毒性,细胞骨架完整性和线粒体功能。我们发现,没有合成的化合物能改善针对MCF7细胞培养物的CDDP活性。然而,TSC2可以有
