My research interests are in the interdisciplinary areas of inorganic chemical biology and bioinorganic chemistry. Our current research goal is to design and study novel cytotoxic metal complexes for targeted therap-eutic and diagnostic applications. Currently we are pursuing following research projects in our laboratory.

I. Therapeutic Applications of Metal Complexes:
The biggest change in drug development, particularly in the anticancer field, has been to move towards molecularly targeted agents to circumvent multidrug resistance. This holds promise of more selective and effective drug administration. Transition metals offer beneficial advantages over their more common counterpart of organic drugs. This includes a diverse range of coordination number and stereochemistry, accessible and tunable redox and electronic proper-ties, ligand substitution etc. We are engaged in the development of specifically targeted cytotoxic metal complexes for various therapeutic and diagnostic applications. Their detailed binding interaction studies with biological targets (nucleic acid, proteins etc.) and fate in biological medium were also investigated. Cytotoxicity and mechanism of actions of these metallodrugs will be evaluated to determine their efficacy and mode of actions.

II. Nitric Oxide Delivery to Biological Targets from Transition Metal Nitrosyl Complexes:
This project aims to design and synthesize transition metal nitrosyl complexes and studying their physicochemical properties and molecular structures. Releasing of nitrosyls from these complexes under various external stimulants will be investigated. We will also study their interaction with potential biological targets (Hb, Mb, GSH etc.) and potential therapeutic applications.

III. Luminescent Lanthanide Complexes and Biological Applications:
Studying chemistry and photophysical properties of lanthanide complexes is an interesting and active research area due to having a wide variety of applications of lanthanide complexes in imaging and diagnostics. Currently we are studying spectroscopic properties, structures and photophysical properties of a series of luminescent lanthanide complexes having organic chromophores as light absorbing antenna molecule for their applications as potential luminescent probes for various analytes or therapeutic applications.
