Dr. Luthra work focuses on i) the study of the signaling pathways in brain to explore the nNOS mediated oxidative stress leading to neurodegeneration in brain and ii) discovery of new chemical entities (NCE) in the therapy of Parkinson's disease ( PD) through adenosine A2ARs. iii) The work also involves to explore the molecular pathways in the pathology of GBM, which may reveal multiple targets for the treatment of GBM to address drug resistance and provide specificity and selectivity in cancer chemotherapy. The research tools in my laboratory include- Bioinformatics:ligand based and structure based drug design, virtual screening, protein structure prediction, synthesis of NCE and their isolation from plants, In vitro screening of NOS inhibitors using the mammalian expression clones of human eNOS, iNOS and nMOS expressed in HEK cell lines, and adenosine A2A receptor antagonists in stably transfected in SKNSH/ SHSY5Y or primary neuronal cells isolated from E18 rats / The anticancer activity of the compounds and their molecular mechanism ( receptor, oxidative and cell cycle mediated) was studied in human glioma U87 cell line. The in vivo study was carried with 5-OHDA induced Parkinson Model in rats.. The anticancer potential was studied with xenograft invivo model of glioblastoma by injecting U87 MG cells in non immunosuppressed mice (subcutaneous and intracranial).
