Compound class: Synthetic organic
Comment: Talabostat (PT-100, or Val-boroPro) is a compound with potent anti-tumour activity. It is a non-selective inhibitor of post-proline-cleaving serine proteases. Talabostat activates macrophages at least in part via inhibition of the serine peptidase, fibroblast activation protein (FAP) , an action that has been examined for anti-cancer utility [2,4-5] and anti-fibrotic potential . More recently talabostat has been reported as an inhibitor of the cytosolic serine dipeptidyl peptidases Dpp8 and Dpp9, and that inhibition of these related enzymes stimulates the immune system via the selective promotion of proinflammatory cell death (pyroptosis) of monocytes and macrophages . This process involves Dpp8/9-induced activation of the NOD-like pattern recognition receptor NLRP1, a protein that acts as an inflammasome sensor, followed by activation of pro-caspase-1 and eventually to pyroptosis .
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.✖
