Research Interest

Our lab aims to answer fundamental questions that lie at the interface of chemistry and biology by integrating the concept of organic chemistry, biochemistry and molecular modeling to perform structure-based design and synthesis of novel chemical entity to unravel the molecular mechanism and develop potential treatment for human diseases.

Probing Endosomal Toll-like Receptors (TLRs). TLRs are members of the larger family of evolutionarily conserved pattern recognition receptors which are critical first line of defence for self-nonself discrimination by the host immune response. Aberrant endosomal TLR activation is implicated in autoreactive inflammation in different autoimmune diseases. The goal is to rationally design selective inhibitors for the nucleic acid-recognizing TLRs for devising novel therapeutic strategies in relevant clinical contexts. 

Epigenetic modifying enzymes as novel therapeutic targets: The main focus is to perform structure-based design and synthesis of small-molecule regulators of epigenetics modifying enzymes such as histone methyltransferases (HMT) as tools to unravel the complex biology of epigenetics and contribute towards epigenetic-based drugs for the treatment of a number of diseases such as cancer, autoimmunity, diabetes, or neurological disorders.

Designing of Small molecules Topoisomerase 1 poison:

Topoisomerases are enzymes that participate in the overwinding or underwinding of DNA. The winding problem of DNA arises due to the intertwined nature of its double-helical structure. DNA becomes overwound ahead of a replication fork. If left unabated, this torsion would eventually stop the ability of DNA or RNA polymerases involved in these processes to continue down the DNA structure. Due to the presence of topoisomerase, this topological problem is solved and cell proliferation runs continuously. So, our structure based designing and synthesis of small molecules is so rational to inhibit the topoisomerase for unwinding the overwound.
