Description: Onvansertib, also know as NMS-P937, PCM-075 and NMS1286937, is a n orally bioavailable, small-molecule Polo-like kinase 1 (PLK1) inhibitor with potential antineoplastic activity. Polo-like kinase 1 inhibitor NMS-1286937 selectively inhibits PLK1, inducing selective G2/M cell-cycle arrest followed by apoptosis in a variety of tumor cells while causing reversible cell-cycle arrest at the G1 and G2 stages without apoptosis in normal cells. PLK1 inhibition may result in the inhibition of proliferation in PLK1-overexpressing tumor cells. PLK1 is a serine/threonine protein kinase crucial in the regulation of mitosis.

Additional Information

onvansertib is an orally bioavailable, adenosine triphosphate (ATP) competitive inhibitor of polo-like kinase 1 (PLK1; PLK-1; STPK13), with potential antineoplastic activity. Upon administration, onvansertib selectively binds to and inhibits PLK1, which disrupts mitosis and induces selective G2/M cell-cycle arrest followed by apoptosis in PLK1-overexpressing tumor cells. PLK1, named after the polo gene of Drosophila melanogaster, is a serine/threonine kinase that is crucial for the regulation of mitosis, and plays a key role in tumor cell proliferation. PLK1 expression is upregulated in a variety of tumor cell types and high expression is associated with increased aggressiveness and poor prognosis
