新型钯配合物[Pd(Phen)(TsserNO)]·H_2O的合成、晶体结构和体外抗肿瘤活性(英文)

A novel palladium(Ⅱ) complex [Pd(Phen)(TsserNO)]·H2O (Phen=1,10-phenanthroline; TsserNO=4- toluenesulfonyl-L-serinate dianion) has been prepared and structurally characterized, the cytotoxicity in vitro has also been investigated by MTT and SRB assays. The complex crystallizes in the monoclinic system, space group P21 with cell parameters a=0.618 64(14) nm, b=1.768 9(4) nm, c=0.990 2(2) nm, β=102.392(4)°, V=1.058 3(4) nm3 and Z=2. The complex had selectivity against HL-60, BGC-823, Bel-7402 and KB cells lines, its cytotoxicity is equal to that of cisplatin against BGC-823 and Bel-7402 cells lines, however it is less potent than cisplatin against HL-60 and KB cell lines.Keywordsantitumor; palladium(Ⅱ) complex; crystal structure     

芳香亚胺与N-(4-甲基苯甲酰)-L-缬氨酸双阴离子合钯(Ⅱ)配合物的合成、晶体结构及体外抗肿瘤活性

本文首次报道了2个钯(Ⅱ)的配合物[Pd(bipy)(4-CH3Bzval-N,O)](1)和[Pd(phen)(4-CH3Bzval-N,O)](2)(bipy=2,2′-联吡啶,phen=1,10-菲咯啉,4-CH3Bzval-N,O=N-(4-甲基苯甲酰)-L-缬氨酸双阴离子)的合成及晶体结构,利用MTT法和SRB法研究了配合物的体外抗肿瘤活性。配合物2属单斜晶系P21/n空间群,其中a=1.162 92(8)nm,b=1.074 03(7)nm,c=1.821 14(12)nm,V=2.232 8(3)nm3,Z=4。结果显示:2个配合物对HL-60,BGC-823,Bel-7402和KB 4种人的肿瘤细胞表现出一定的活性和选择性,但其活性均小于顺铂。
