4% for the lung adenocarcinoma A-549 cell line at a concentration of 10−6 mol·L−1, while complex 1 shows only a marginal activity against the same cell lines. The reactivity of the two complexes towards γ-glutathione (GSH) has been investigated and is discussed in association with their different cytotoxicity. (© Wiley-VCH Verlag GmbH & Co.

两种新型 CuII 配合物 [Cu(CMQA)(
H2O)] (1) (CMQA = N-羧甲基-L-甲
硫氨酸-N'-8-
喹啉酰胺) 和 [Cu(MQA)(OAc)] (2) (MQA = L-甲
硫氨酸-N'-8-
喹啉酰胺,OAc = CH3COO-) 已合成并进行结构表征。配合物 1 在空间群为 P212121 [a = 5.556(1) A, b = 15.002(3) A, c = 20.886(4) A] 的正交晶系中结晶,而配合物 2 在空间群为 C2 的单斜晶系中结晶 [a = 28.463(6) A, b = 5.264(1) A, c = 13.345(3) A, β = 109.142(3)°]。在这两种配合物中,CuII 中心由
配体的三个 N 原子和 (1) 或 OAc (2) 的一个 O 原子配位。已针对鼠白血病 P-388 和肺腺癌 A-549
细胞系测试了这
