Pfizer, and Professor Although only a four-person company at this stage, John T. Groves, holder HepatoChem already has numerous clients ranging from of the Hugh Stott Taylor start-ups to big Pharma. “Our clients are very satisfied with Chair of Chemistry at the quality and speed of our service.” Dr. Bazin stated that Princeton University. the business in liver metabolites is $100 million per year HepatoChem was started and their business is expected to grow rapidly for a number in the Groves lab at of years. “This is very exciting to see our company growing Princeton, but in August in this economy.” u 2011 moved to the Biotech InnoVenture Center in Beverly, MA.

Business Development Manager Shelly Amster at a recent NESACS Monthly Meeting. A subsequent interview was arranged with HepatoChem President, Marc Bazin, at their Beverly facility. HepatoChem uses technology based on many years of metalloporphyrin research conducted at Princeton in the Groves laboratory. A variety of metalloporphyrins (Fig. 1) Fig. 1: A Synthetic Metalloporphyrin are used to simulate liver metabolism and oxidatively con- vert drug candidates in vitro to metabolites in milligram to gram quantities. This is in stark contrast to the nanogram quantities available by in vitro or in vivo biological methods. Easy access to large quantities of metabolites allows struc- ture determination and additional evaluation and testing, which would not be possible without the larger quantities available from HepatoChem’s biomimetic methods. “The technology we developed at HepatoChem can produce not Fig. 2. Graphical illustration of metabolites formed by the only metabolites but also new analogues of lead candidates oxidation of aminopyrine with HepatoChem’s technology. that could have better biological properties than the original drug. This positions it as an important tool for drug discov- ery.” Initial screening is done in 96-well plates loaded with the test molecule. A series of test reactions are then con- ducted in which the metalloporphyrin, the oxidant, and the solvent are varied. These experiments are then analyzed by Fig. 3: Metabolites formed by biomimetic oxidation of LC-MSMS to identify a profile of metabolites and allows Tolbutamide. rapid selection of conditions to produce the targeted metabolite. (Fig 2) A second round of experiments allows optimization and larger scale production of any or all of the metabolites generated in the screen.
