β-Carboline copper complex as a potential mitochondrial-targeted anticancer chemotherapeutic agent: Favorable attenuation of human breast cancer MCF7 cells via apoptosis.

The development of preferentially selective cancer chemotherapeutics is a new trend in drug research. Thus, we designed and synthesized novel ternary complexes, [Cu(tryp)(Hnor)(DMSO)]NO ( and [Zn(tryp)(Hnor)(DMSO)]NO (tryp = DL-Tryptophane; Hnor = Norharmane, β-carboline; DMSO = Dimethyl sulfoxide), characterized with elemental analysis, FTIR, UV-vis, FL, NMR, ESI-MS, and molar conductivity. Furthermore, the TD-DFT studies with UV-vis and FTIR validated the proposed structures of and .
