AT7519M selectively binds to and inhibits cyclin dependent kinases (CDKs), which may result in cell cycle arrest, induction of apoptosis, and inhibition of tumor cell proliferation. CDKs are serine/threonine kinases involved in regulation of the cell cycle and may be overexpressed in some types of cancer cells."}]
