This study aims to synthesize, characterize, and evaluate the anticancer potential of a manganese(II) cysteine-alanine dithiocarbamate complex to overcome challenges posed by drug resistance in breast cancer treatment. The Mn(II) cysteine-alanine dithiocarbamate complex was synthesized using manganese chloride, alanine, cysteine, and carbon disulfide under controlled conditions. The synthesized complex exhibited strong thermal stability (melting point: 200 – 218 °C) and weak electrolyte behavior (conductivity: 1.5 mS/cm at 28 °C). Characterization techniques included UV-Vis (absorption peaks at 253, 274, 284, 294, and 305 nm), FTIR (notable bands at 3338.78, 2918.30, 1597.06 and 689.30 cm⁻¹), XRD (sharp peaks at 28°, 32°, 43°, 60°, lattice parameters a = 3.40 Å, b = 2.48 Å), and SEM-EDS (porous morphology with dominant Mn and S content). Molecular docking revealed strong interactions with estrogen receptor alpha (ERα) through hydrogen bonds, van der Waals forces, and salt bridges, with a binding energy of −59.93 kJ/mol. Cytotoxicity was evaluated on MCF-7 cells using the MTS assay, revealing a dose-dependent inhibition with an IC50 value of 61.66 µg/mL. The Mn(II) cysteine-alanine dithiocarbamate complex exhibits promising structural stability, receptor binding affinity, and cytotoxic potential against MCF-7 breast cancer cells, highlighting its potential as an effective and selective anticancer agent. © 2025, Walailak University.
