methotrexate is an approved drug (FDA (1953), EMA (2016))
Compound class: Synthetic organic
Comment: Methotrexate is a folate (folic acid) analogue that is classified as an antimetabolite and antifolate drug, and a disease-modifying anti-rheumatic drug (DMARD). It is used clinically for its antiproliferative and anti-inflammatory effects. The primary action of methotrexate is inhibition of the enzyme dihydrofolate reductase (DHFR). DHFR is essential for the production of precursors that are required for de novo purine synthesis.
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.✖
