Medicinal Chemistry As a complement to its internal capabilities, Chromocell has entered into collaboration with the Organic Chemistry Collaborative Center (OCCC) of the division of Experimental Therapeutics at Columbia University in New York. The Division of Experimental Therapeutics at Columbia University’s Medical Center was founded by the Principal Investigator, Donald W. Landry M.D., Ph.D. with a specific goal of bringing organic chemistry to one of the most productive and target-rich medical centers in the country. In 2003, this progress led to the founding of the OCCC. The Center focuses on “bench to bedside” collaborations and supports biomedical research by providing small molecules (probes) to elucidate physiology and pathophysiology, and to validate targets for drug discovery. The Center is well-equipped with its own major instruments, and it has current staff of eight Ph.D. organic chemists.
