The overarching goal of Sharma lab is to design and develop novel-molecular reactivity and molecular function to ultimately accelerate the discovery of new therapeutics.
The emergence of resistance to chemotherapeutic drugs is a prominent challenge in the treatment of cancer as well as bacterial infections. In order to overcome this challenge, it is vital to not only develop drugs with novel mechanisms of action but also to expedite the chemical synthesis of these next generation anticancer and antibacterial agents.
Our lab aims to develop novel synthetic methodologies that allow efficient construction of molecules possessing interesting structural, biological and physical properties. Another goal is to design and develop compounds that potently block the proliferative action of estrogen receptors in breast cancer. Our research program spans the areas of organic synthesis, chemical biology and medicinal chemistry.
