Isolate protein involved in disease (2-5 years)
Find a drug effective against disease protein (2-5 years) Scale-up
FDA approval (2-3 years)
Technology is impacting this process GENOMICS, PROTEOMICS & BIOPHARM. Potentially producing many more targets and “personalized” targets
HIGH THROUGHPUT SCREENING
Screening up to 100,000 compounds a day for activity against a target protein
Identify disease
VIRTUAL SCREENING Using a computer to predict activity
Isolate protein
COMBINATORIAL CHEMISTRY Rapidly producing vast numbers of compounds
Find drug
MOLECULAR MODELING
Computer graphics & models help improve activity
IN VITRO & IN SILICO ADME MODELS
Preclinical testing
Tissue and computer models begin to replace animal testing

Why encapsulate materials ? • To achieve controlled/remote-release. • Make active materials easier/safer to handle. • Compartmentalize multiple component systems. • Protect sensitive materials from their environment. • To turn liquids into powders/solids. All require a specific morphology
Why Nano-Medical in India? • Targets key industries in India – Pharmaceuticals – Analytical Instruments – Medical Devices
• 3 of the 10 highest wage India industries • 3 times as many jobs exist in these industries as in India’s IT industries.
Why it is in SPS? Comprehensive university on a compact campus Institutional support and priority (2007) “…Pharmacy & biotechnology, particularly at the interface of medicine and nanoscience.” Interdisciplinary faculty with critical mass and focus
SPS NanoMedical Research Center Vision: Create and harness nano-structured material technologies for the prevention, detection and treatment of diseases in order to enhance the public health and to expand the Orissa and national economies too. Focus: Faculty: Funding: Product:
Develop nanostructures for medical diagnostics and therapeutics 140 faculty in eight academic departments >4000 students and PhD,100 supportive staff members including Hon. Vice Chancellor. State of Orissa Centers of Excellence $19.9 million for FY2003-07 with milestones Knowledge / Publications / Translational Science
