Synthetic organic
Comment: Pimasertib is an orally bioavailable small-molecule inhibitor of the mitogen-activated protein kinases MEK1 and MEK2 (MEK1/2) with potential antineoplastic activity [4]. It binds to an allosteric site, distinct from the ATP binding site [2] and as such prevents activation rather than inhibiting catalysis.
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. ✖ |

Summary of Clinical Use |
Pimasertic is being assessed in Phase 2 clinical trials for ovarian cancer (in combination with SAR245409, PubChem CID 16123056; NCT01936363) and N-Ras mutated cutaneous melanoma (versus dacarbazine, PubChem CID 5353562; NCT01693068). |
Mechanism Of Action and Pharmacodynamic Effects |
MEK1/2 (MAP2K1/K2) are dual-specificity threonine/tyrosine kinases that play key roles in the activation of the RAS/RAF/MEK/ERK pathway and are often upregulated in a variety of tumor cell types [1]. Pimasertib selectively binds to and inhibits the activity of MEK1/2, preventing the activation of MEK1/2-dependent effector proteins and transcription factors, which may result in the inhibition of growth factor-mediated cell signaling and tumor cell proliferation [3]. |
