• Biologische Aktivität

  tryptophan hydroxylase (tph) is a key enzyme in the synthesis of serotonin. serotonin plays important physiological roles both peripherally and centrally. lx-1031 is a heterocyclic substituted phenylalanine analog, an oral small molecule tryptophan hydroxylase (tph) inhibitor that reduces synthesis of serotonin (5-ht) peripherally and is being developed for conditions characterized by excess 5-ht expression such as diarrhea-predominant irritable bowel syndrome (ibs-d) and, possibly, carcinoid diarrhea.

• in vitro

  lx-1031 inhibits tph1 at its concentration of 10-8–10-7 mol l-1 range [1].

• in vivo

  with oral administration of lx-1031 in mice, the 5-ht reductions in the jejunum relative to control were ~33%, 51%, and 66% with the 15, 45 and 135 mg/kg/day doses, respectively; the effect of 5 mg/kg/day on gi 5-ht content was not significantly different from control [2].
