Presentation Abstract

Alzheimer's Disease onset is characterized by memory loss due to extracellular deposits of amyloid B and plaque formation, often causing diminishing neurological synaptic functioning and neurodegeneration. Oxidative stressors, caused by radical oxidative species such as H2O2, have shown to enhance and/or initiate Alzheimer's disease through lipid peroxidation, DNA damage, and apoptosis. Phidianidine A analogues derived from Phidiana militaris have exhibited neuroprotective effects in neuroblastoma cell lines. Guo's group, through substituting the linker region of phidianidine A with a biaryl linker, showed the greatest of antioxidant activity against H2O2. The addition of aromatic compounds, 4-ethoxy benzene bound to furan, has shown potential in reducing H2O2-induced damage along with prevention towards oxygenglucose deprived neurotoxicity. Development of further phidianidine analogues, such as replacing the 1,2,4-oxadiazole ri g with a furan ring or substitution on the indole ring with additional aromatic substituents, may help to produce more potent ROS inhibitors. New phidianidine analogues will be synthesized through a cross-coupling approach that will enable the late-stage installation of different aromatic groups and substituted indoles. A necessary step in this approach is the selective introduction of bromine to the 5-position of a substituted furan. A variety of conditions have been studied to identify the most effective procedure.
