Discovery Partners

Discovery Partners International (DPI) was a leading provider of drug discovery services and chemical libraries to the global pharmaceutical and biotechnology industries. Founded in 1995 and headquartered in San Diego, the company specialized in high-throughput screening, combinatorial chemistry, and lead optimization. DPI's integrated platform was designed to reduce the time and cost of drug discovery by providing high-quality chemical compounds and sophisticated screening technologies. The company went public on the NASDAQ in 2000 and maintained significant collaborations with major pharmaceutical firms like Pfizer and Bristol Myers Squibb. In 2006, DPI merged with Infinity Pharmaceuticals in a reverse merger, shifting the combined entity's focus toward internal drug development.
