About the project
Her research project will identify novel derivatives of curcumin as potential anti-Alzheimer agents, and develop a nanocarrier drug delivery system for the effective delivery of these derivatives. Alzheimer’s disease (AD) is the most common cause of dementia among older adults and there are only a limited number of drugs available for treatment of AD. Most of these can only treat the symptoms, and are associated with side effects. Curcumin, a natural chemical produced by plants of the Curcuma longa species and the primary bioactive compound in turmeric, has been shown to improve cognitive function in AD patients; however it it has low bioavailability and is unstable in most body fluids. The project will study newly synthesized curcumin derivatives for their neuroprotective capabilities, as well as utilize nanoparticles to develop a targeted drug delivery system that can help them overcome the blood-brain barrier.
