National Institutes of Health (COBRE)
Center for Cancer Experimental Therapeutics
Core C: High Throughput Screening
Project 5: Total Synthesis and SAR Studies of Salinosporamide A
Core C of the COBRE program assists COBRE investigators and other researchers in the development and execution of bioassays to identify bioactive compounds from chemical libraries that affect functions of enzymes, receptors or cells for their potential use as anticancer agents. Project 5 proposes a total synthesis of salinosporamide A and subsequently the method developed will be applied towards investigation of the SAR profile, and design/development of modified analogs in search of improved bioactivity.
Role: Co-Investigator of Core C
