Nadeem Bukhari, Imtiyaz Ahmad Bhatt, Ajaz Ahmad, Shahnawaz Ahmed, Athar Adil Hashmi, Liang Jiang, Shaojuan ChenAbstractThe development of drug resistant strains of the pathogenic fungi despite the availability of large number of drugs demands the development of new and more potential drug molecules. Dendrimer based drug molecules are comparatively less researched upon and a recent advancement in this field. The present study is concerned with the preparation of macromolecular ligand and its complex using ethylenediamine and methylmethacrylate as starting material. The reaction goes via Michael addition reaction and synthesized dendritic units were used as ligands to obtain metal-ligand complexes. Obtained ligand and its complex were characterized in terms of different techniques such as FTIR, 1HNMR, ESI-MS, UV-Vis and Elemental analysis. Further, the ligand and its complex were used to determine antifungal activity against C. albicans ATCC 90028 by MICs and Disk diffusion assay. Comet assay and Molecular docking techniques were used to show toxicity effects and ligand–DNA interactions respectively. Ligand and its complex were obtained in very good yield with square planar geometry and having good antifungal potential against C. albicans. It was also found from Molecular docking and Comet assay, that the Copper complex interacts strongly with DNA and shows le...
