I started my research as a medicinal chemist (heterocyclic chemistry) in 2005 with synthesis of biologically active indole derivatives (J Enzyme Inhib Med Chem, 2009; 24 (2):537-44). The majority of my work involves target based synthesis of small heterocyclic molecules such as ligase (I & IV), HSP90, galectin and BCL2 inhibitor. The development of DISARIB (BCL2 inhibitor) is my latest finding. Biopolymer based drug delivery is another area of my research.
