制备了一系列具有二乙基二硫代氨基甲酸酯配体和三种不同金属(Ni、Cu、Zn)的三种配合物,通过X射线晶体学证实,并在人乳腺癌MDA-MB-231细胞中测试。锌和铜的络合物,但不是镍络合物,被发现是更积极的对细胞26 S蛋白酶体比对纯化的20 S蛋白酶体核心颗粒。一种可能的解释是19 S蛋白酶体盖中JAMM结构域的抑制。
A series of three complexes with diethyldithiocarbamate ligand and three different metals (Ni, Cu, Zn) was prepared, confirmed by X-ray crystallography, and tested in human breast cancer MDA-MB-231 cells. Zinc and copper complexes, but not nickel complex, were found to be more active against cellular 26S proteasome than against purified 20S proteasome core particle. One of the possible explanations is inhibition of JAMM domain in the 19S proteasome lid.
