on the wide clinical use and successes of the platinum drugs like cisplatin and oxaliplatin, we investigated the synthesis and potential anticancer efficacy of alternative platinum complexes. A series of nine cationic square planar platinum(II) complexes were synthesized and characterized and then evaluated for their anticancer activity. The complexes were of the type [Pt(diimine)(Ln-κO,S)]+ where
尽管人们共同努力开发靶向癌症治疗方法,但这些疗法仍受到耐药性快速发展和严重药物不良反应的困扰。基于顺铂和奥沙利铂等铂类药物的广泛临床应用和成功,我们研究了替代铂配合物的合成和潜在的抗癌功效。合成并表征了一系列九种阳离子方形平面铂( II )络合物,然后评估了它们的抗癌活性。配合物的类型为 [Pt(二亚胺)(L n -κ O , S )] +,其中二亚胺是 1,10-菲咯啉 (phen)、5,6-二甲基-1,10-菲咯啉 (dmp) 或二吡啶并[3,2- f :2',3'- h ]喹喔啉 (dpq) 和 L n -κ O , S代表各种N , N-二丁基-N'-酰基硫脲配体。针对两种肺癌细胞系(A549 和 H1975)和结直肠癌细胞系 HT-29 评估了合成复合物的抗癌活性。确定了大多数细胞毒性化合物的50%抑制浓度(IC 50 )并评估了细胞死亡模式。结构-活性关系表明,具有二亚胺配体的
