4-(3-chloro-2-fluorophenoxy)-1-[[6-(2-thiazolylamino)-2-pyridinyl]methyl]-1-cyclohexanecarboxylic acid is an aromatic ether.
MK-5108 has been used in trials studying the treatment of Cancer, Neoplasms, Tumors. Aurora A Kinase Inhibitor MK5108 is an orally bioavailable, highly selective small molecule inhibitor of the serine/threonine protein kinase Aurora A, with potential antimitotic and antineoplastic activity. Aurora A kinase inhibitor MK5108 binds to and inhibits Aurora A kinase, which may result in disruption of the assembly of the mitotic spindle apparatus, disruption of chromosome segregation, and eventually inhibition of cell division, proliferation and an induction of apoptosis in cells overexpressing Aurora A kinase. Aurora A kinase localizes to the spindle poles and to spindle microtubules during mitosis, and is thought to regulate spindle assembly. Aurora kinases are overexpressed in a wide variety of cancers. Selectivity: >1000-fold selectivity for Aurora-A over other kinases (e.g., CDK1, EGFR, VEGFR2) [1] - Clinical relevance: Designed to overcome resistance to taxanes by targeting Aurora-A-driven mitotic defects [1] - Synergy with docetaxel: Combined treatment enhanced mitotic arrest and apoptosis via dual inhibition of microtubule dynamics and Aurora-A signaling [1] |
