Novel thiosemicarbazone complexes as anticancer agents: Synthesis, characterization, cytotoxicity, docking, and density functional theory studies

“…There are electronic absorption bands in DABT– Co (II), Ni (II), and Cu (II) complexes regarded to free DABT with red or blue shift in bands due to π – π * and n – π * as a result of the chelation process 38 . DABT complexes exhibited absorption bands in the range of (448–418 nm) may be owing to intramolecular LMCT 39 . In addition, there are electronic absorption bands appeared at 682, 634, and 719 nm for DABT– Co (II), Ni (II), and Cu (II) complexes, respectively, referred to a tetrahedral structure around the metal ion 40–42 .…”
