Compound class: Synthetic organic
Comment: Rodatristat (KAR5417) inhibits both isoforms of L-Tryptophan hydroxylase (TPH) . The TPH enzymes are responsible for biosynthesis of 5-HT. TPH1 is expressed by intestinal enterochromaffin cells where most peripheral 5-HT is formed, and THP2 is exclusively expressed in the CNS and generates 5-HT in the brain. Rodatristat acts as a serotonin synthesis inhibitor. As rodatristat cannot cross the blood-brain-barrier its activity is restricted to inhibition of peripherally expressed TPH1 and it should not produce the undesirable psychiatric side-effects that are known to result from any reduction in central 5-HT level.
Inhibition of serotonin synthesis is being actively pursued as a mechanistic approach for application to the treatment of the expansive range of diseases that have been associated with a dysfunctional peripheral serotonin system (carcinoid syndrome, gastro-intestinal diseases, fibrotic diseases, NAFLD, atherothrombotic diseases, pulmonary arterial hypertension and some cancers and immune diseases [1,3]).
Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖
