Molecular basis of cancer metastasis and identification of new therapeutic strategies to limit resistance, recurrence of cancer. Studies are focused on role of the tumor necrosis factor receptors and the epidermal growth factor receptors in breast, lung and pancreatic cancers. Employ structural biology for drug discovery and develop molecular probes for tumor imaging and drug delivery.
Developed small peptidomimetics of Herceptin and small molecule probes to tumor necrosis factor receptors. The small molecular probes are being engineered for cancer diagnosis, and treatment of breast cancer and autoimmunity pathologies. Developed a novel drug discovery platform, "cavity-induced allosteric modification" for a new class of allosteric inhibitors of protein complexes.
Current investigations include:
Co-regulation of ErbB and RANK, RANKL , osteoprotegrin (OPG) and TRAIL receptor complexes in breast, lung and pancreatic cancers. Small molecular probes have been developed targeting these receptor complexes using structural biology techniques, and the current investigations include developing therapeutics and strategies for tumor imaging and nanoparticles for tumor-specific drug delivery.
