A series of CO‐releasing molecules M(CO)5 L (M = Mo, W and Cr), (1, 2, 3, L = glycine methyl ester; 4, 5, 6, N‐methylimidazole; 7, 8, 9, 2‐aminopyridine; 10, 11, 12, 3‐aminopyridine; 13, 14, 15, 4‐aminopyridine), were synthesized. All complexes have been characterized by NMR, IR and electrospray ionization mass spectroscopy; the octahedral structures of 14 and 15 were also established by X‐ray crystallography
一系列CO释放分子M(CO)的5 L(M = Mo,W和Cr)的,(1,2,3,L =甘氨酸甲酯; 4,5,6,Ñ甲基咪唑; 7,8,9,2-氨基吡啶; 10,11,12,3-氨基吡啶; 13,14,15,4-氨基吡啶),合成。所有配合物均已通过NMR,IR和电喷雾电离质谱进行了表征。14和15的八面体结构也通过X射线晶体学确定。此外,评估了所有复合物的毒性,药代动力学和代谢过程。通过MTT测定对成纤维细胞系增殖的细胞毒性作用。在络合物中,Mo络合物1显示出最低的细胞毒性(IC 50 = 597 µmol l -1),W络合物2显示出显着的毒性作用,IC 50 = 52 µmol l -1。在具有相同配体的情况下,配合物的毒性作用按金属元素W
