Gordon Wayne Gribble

Professor of Chemistry
The Dartmouth Professor of Chemistry

Professor Gribble's research program covers several areas of organic chemistry, most of which involve synthesis, including novel indole chemistry, triterpenoid synthesis, DNA intercalation, and new synthetic methodology. Of prime interest is the synthesis of bis-acridines that act as DNA double intercalators, one of which is active against human glioblastoma cells. In the area of new synthetic methodology, Dr. Gribble and his students have discovered new chemistry of nitroindoles. A third area of research is the synthesis and biological activity of triterpenoids in the chemoprevention of cancer and other diseases related to inflammation. One of these synthetic triterpenoids, "bardoxolone methyl" has entered Phase 3 clinical trials for the treatment of chronic kidney disease in diabetes patients.

Dr. Gribble also has a deep interest in naturally occurring organohalogen compounds, and in the chemistry of wine and wine making.
