LX1031 is an orally-dosed drug candidate for irritable bowel syndrome and other gastrointestinal disorders. LX1031 was generated by Lexicon medicinal chemists, and its target was internally identified as a key control point for the regulation of peripheral serotonin levels. LX1031 is designed to act locally in the gastrointestinal tract by reducing the serotonin available for receptor activation, without affecting serotonin levels in the brain or its central nervous system functions.
