Comment: PF-04859989 was identified as a potent, irreversable and selective inhibitor of human and rat kynurenine aminotransferase II (KATII; a.k.a. aminoadipate aminotransferase AADAT) [1-2] . An X-ray crystal structure of the enzyme co-crystalised with an inhibitor has been reported [1]. In vivo pharmacokinetic and efficacy studies in rat show it to be brain-penetrant, reducing brain kynurenic acid by 50%. KAT inhibitors are expected to exhibit neuroprotective effects, that may be beneficial for the treatment of neurodegenerative and cognitive impairment disorders [3].
Ligand Activity Visualisation ChartsThese 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. ✖ |
