Description: Telotristat (formerly known as LP-778902; LP778902) is the active metabolite of LX1606 (LX-1606; Telotristat etiprate) which is an orally bioavailable and small-molecule inhibitor of tryptophan hydroxylase (TPH, IC50 = 0.028 μM) with potential antiserotonergic activity.

Protocol	In Vitro	Telotristat is the active moiety of telotristat etiprate. Telotristat etiprate is an ethyl ester prodrug which is hydrolyzed to telotristat. Telotristat etiprate is orally available serotonin synthesis inhibitor for the treatment of carcinoid syndrome.
Protocol	In Vivo	Telotristat etiprate is present in very low levels after oral administration. These low levels are due to rapid hydrolysis into the active moiety telotristat. The half-life ranges from approximately 4-12 h. There is no accumulation of telotristat with multiple dose administration over 2 weeks. Exposure to telotristat is approximately dose proportional.

These protocols are for reference only. InvivoChem does not independently validate these methods.
