Given that tryptophan hydroxylase 1 (TPH1) is the rate limiting enzyme in the biosynthesis off serotonin, it represents an attractive target to regulate peripheral serotonin. Following up to our first disclosure, we report a new chemotype of TPH1 inhibitors where-by the more common central planar heterocycle has been replaced with an open-chain, acyl guanidine surrogate. Through our work, we found that compounds of this nature provide highly potent TPH1 inhibitors with favorable physicochemical properties that were effective in reducing murine intestinal 5-HT in vivo. Furthermore, we obtained a high resolution (1.90A) X-ray structure crystal structure of one of these inhibitors (compound 51) that elucidated the active conformation along with revealing a dimeric form of TPH1 for the first time.
