Compound class: Synthetic organic
Comment: Compound 9 [PMID: 26006010] is a reversible BTK inhibitor that was designed to have a long target residency time with a resulting increase in the duration of in vivo target engagement, and with the overall aim of improving in vivo drug efficacy . Compound 9 has a cysteine-reactive, inverted cyanoacrylamide scaffold structure that interacts with Cys481, a residue that lies outwith the catalytic domain of the enzyme but close to the ATP pocket (and is also a target of the irreversible inhibitor ibrutinib). It has good aqueous solubility and is orally bioavailable.
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.✖
