platinum(II) complexes Pt1–Pt8 with substituted 3‑(2′‑benzimidazolyl) coumarins were successfully synthesized and characterized by single crystal X-ray diffraction analysis, nuclear magnetic resonance spectroscopy (NMR), electrospray ionization-mass spectrometry (ESI-MS), infrared spectrophotometry (IR) and elemental analysis. Crystallographic data of these Pt1–Pt8 complexes showed that the Pt(II) has
已成功合成了八种新的具有取代的3-(2'-苯并咪唑基)香豆素的铂(II)配合物Pt1 - Pt8,并通过单晶X射线衍射分析,核磁共振波谱(NMR),电喷雾电离质谱(ESI)进行了表征-MS),红外分光光度法(IR)和元素分析。这些Pt1 - Pt8配合物的晶体学数据表明,Pt(II)扭曲了四坐标的方形平面几何形状。Pt1 – Pt8被发现在体外对顺铂耐药的SK-OV-3 / DDP癌细胞具有高的细胞毒活性,且IC 50低从1.01–10.32μM,但对正常的HL-7702细胞具有低细胞毒性。进一步的研究表明,Pt1 – Pt3通过线粒体功能障碍信号传导途径诱导SK-OV-3 / DDP癌细胞凋亡。我们的发现还表明,Pt1是靶向c-myc启动子元件的端粒酶抑制剂。
