Overview

The research in medicinal chemistry division includes the design and synthesis of new medicinal agents, development of new concepts for the design of selectively active ligands, improvement of existing drugs by molecular modifications and structural elucidation of biologically active natural products. The major program is aimed at chemistry-biology interface. The main focus of research is to discover novel compounds using rational design approaches based on ligand and structural information derived from clinical compounds to treat infectious diseases such as tuberculosis, cancer, inflammation, obesity, and neurodenerative diseases.
The department has state-of-the art research facilities. The students, who are pursuing their doctoral degree, have opportunity to gain expertise in organic and medicinal chemistry as well as computational chemistry. They also have an opportunity to broaden their knowledge in the area of drug discovery, molecular biology, pharmacology and biochemistry.
