DNA binding, molecular docking and apoptotic inducing activity of nickel(<scp>ii</scp>), copper(<scp>ii</scp>) and zinc(<scp>ii</scp>) complexes of pyridine-based tetrazolo[1,5-a]pyrimidine ligands
human cancercell lines such as lung (A549), cervical (HeLa), colon (HCT-15) and a non-cancer human embryonic kidney cellline revealed that the complexes selectively inhibit the growth of cancercells and are inactive against non-cancer cell lines, whereas the ligands were found to be inactive with both cancer and non-cancer cell lines. The IC50 values of the complexes revealed that the copper(II) complexes
六个具有生物活性的单核铜(II),镍(II)和锌(II)配合物[ML 1 Cl 2 ](1-3)和[M(L 2)2 Cl 2 ](4-6)四唑[1,5- a ]嘧啶核心配体,乙基5-甲基-7-吡啶-2-基-4,7-二氢四唑[1,5- a ]嘧啶-6-羧酸盐(L 1)和乙基5合成并表征了-甲基-7-吡啶-4-基-4,7-二氢四唑并[1,5 - a ]嘧啶-6-羧酸盐(L 2)。配体的分子结构(L 1&2)和配合物6通过单晶X射线衍射测定。X射线晶体结构6证实其具有扭曲的四面体结构以及ZnN 2 Cl 2配位环境。所有复合物在室温下均显示出异常强的发光。铜(II)配合物(2和5)的电顺磁共振谱显示出四条线,具有正方形的平面几何形状,核自旋为3/2。复合物与小牛胸腺DNA的DNA结合研究表明复合物2和5结合在DNA的凹槽中。这些结果得到了分子对接研究的进一步支持。配体(L 1&2)和复合物(1-
