motif was detected. The Schiff base ligand L1H was anchored to silica and treated with Zn(OAc)2·2H2O to form the heterogeneous ZnII system. This was characterised by 13C1H} CP/MAS NMR spectroscopy. All homogeneous and heterogeneous catalysts were assessed for the ring-opening polymerisation of rac-lactide at 130 °C in the absence of solvent, using unsublimed monomer. All catalysts offered good conversions

values associated with these complexes were much lower than the conventional drug cisplatin. Apoptosis‐induced cell death was confirmed from the DNA fragmentation studies and Hoechst 33342 staining. The 2′,7′‐dichlorofluorescein diacetate (DCFDA) assay indicates that the complex mediated reactive oxygen species (ROS) generation is accountable for governing the apoptosis mechanism via oxidative cell distress
