Description: Milciclib, also known as PHA-848125 or PHA-848125AC, is an orally bioavailable inhibitor of cyclin-dependent kinases (CDKs) and thropomyosin receptor kinase A (TRKA), with potential antineoplastic activity. CDK2/TRKA inhibitor PHA-848125 AC potently inhibits cyclin-dependent kinase 2 (CDK2) and exhibits activity against other CDKs including CDK1 and CDK4, in addition to TRKA. Inhibition of these kinases may result in cell cycle arrest and apoptosis of tumor cells that express these kinases. CDKs are serine/threonine kinases involved in regulation of the cell cycle and may be overexpressed in some cancer cell types.

Milciclib (PHA-848125) is a spectrum selective multi-kinase inhibitor of cyclin-dependent kinases initially identified in a CDK2 inhibitor project, as a potent inhibitor of the CDK2/Cyclin A complex. It possesses an unusual kinase inhibitory profile, being active also against other selected members of receptors tyrosine kinases, src family and splicing kinases. Uncontrolled cell proliferation is a hallmark of cancer cells. Alterations of the expression and/or genetic mutations of Cdks and other components of the pRB pathway, controlling the correct entry and progression through the cell cycle, were reported in more than 90% of human neoplasms. Milciclib is currently in phase II as single agent in thymic carcinoma. (source: http://www.nervianoms.com/en/oncology-en/pipeline/milciclib.html).
