Small Molecules Mimicking Key Brain Growth Factor Identified By Study

Stanford University Medical Center.

The patents for these four compounds are held by the University of North Carolina and UCSF, where Longo worked before coming to Stanford. While at UNC, Longo founded PharmatrophiX, a company focused on the commercial development of small molecules similar to and including those identified in this study.
