TPT-004
Based on 1 Customer Validation
TPT-004 is a selective and oraly active tryptophan hydroxylases (TPH) inhibitor with IC50s of 77 nM and 16 nM for TPH1 and TPH2, repsectively. TPT-004 exhibits exceptional selectivity for TPH1 compared with other members of the AAAH family. TPT-004 shows efficacy peripheral serotonin attenuation and colorectal tumor growth in mice[1][2].
