Sivakumar Annadurai received his B.S. in Pharmacy from The Tamilnadu Dr.MGR Medical University, Chennai, India in 1998 and M.S. in Pharmaceutical Chemistry from Birla Institute of Technology, Mesra, Ranchi, India in 2000. He worked as a Lecturer in Sri Ramachandra College of Pharmacy, Sri Ramachandra University, Chennai, India for four years. Then he moved to Temple University School of Pharmacy, Philadelphia where he completed his Ph.D in Pharmaceutical Sciences under the guidances of Dr. Daniel Canney and Dr. Magid Abou-Gharbia. His dissertation titled “Lead generation using a privileged structure-based approach” involved the synthesis, characterization and testing of a structurally diverse compound library (60 compounds) based on a privileged structure. Several promising leads displaying a wide range of biological activity (antimicrobial, modulators of muscarinic and serotonin receptors) were identified. During his graduate studies he was also involved in another project involving the development of a capillary electrophoresis mobility shift assay (CEMSA) for screening inhibitors of high mobility group protein Box1 (HMGB1)/double stranded DNA (dsDNA) complex formation. Preliminary assay results indicated that the inhibition of DNA-HMGB1 binding by glycyrrhizin and its derivatives occurs via interaction with micelles/aggregates rather than individual triterpene molecules. He is presently a Postdoctoral Research Fellow in the Moulder Center for Drug Discovery Research at Temple University School of Pharmacy. His present research involves the synthesis and brain pharmacokinetic studies of 5-Lipoxygenase (5-LO) inhibitors. The inhibitors with favorable physicochemical properties will be chosen for the development of PET ligands for imaging 5-LO in the brain.
