Among them, cathepsin B (CTSB), a cysteine protease, is notably involved in the development of breast cancer and neuroblastoma. In this study, we explored the potential of darifenacin as a repurposed therapeutic targeting CTSB, using molecular docking and simulation studies which demonstrated a significantly lower binding energy against CTSB (-456.268 kJ/mol) compared to its known inhibitor, aloxistatin (-36.601 kJ/mol). The cytotoxic efficacy of darifenacin was evaluated on IMR-32 (neuroblastoma) and MCF-7 (breast cancer) cells, yielding half-maximal inhibitory concentrations (IC50) of 38.14 and 39.96 µM, respectively. Darifenacin effectively inhibited CTSB enzymatic activity by ~1.82 and ~1.75-fold in IMR-32 and MCF-7 cells, respectively, triggering intracellular ROS generation, mitochondrial membrane potential depolarization, and cell cycle arrest. These events culminated in apoptosis-mediated cell death, with apoptotic populations reaching 51.39% in IMR-32 and 40.6% in MCF-7 cells, respectively. Additionally, darifenacin disrupted lipid droplet accumulation, cellular migration, and colony and sphere-forming abilities in both cell lines.

Metal complexes presenting hemilabile ligands could combine structural toxicity upon full coordination of the ligand and reactive toxicity upon ligand partial decoordination and direct coordination of the metal center to biological targets. To investigate the relevance of hemilability in the case of Au(III) complexes, we synthesized eight open biphenyl gold(III) N-heterocyclic carbene complexes coined BGC of general formula [(C^C)Au(NHC^het)Cl] where het is a pyridine-type entity and C^C is 4,4'-diterbutylbiphenyl.
