NCIt definition : An orally bioavailable small molecule inhibitor of the salt inducible kinases 2 (SIK2)
and 3 (SIK3), with potential antineoplastic activity. Upon oral administration of
SIK inhibitor GRN-300, this agent targets, binds to and blocks the activity of SIK2
and SIK3. This prevents SIK2/3-mediated signaling, blocks centrosome separation, and
inhibits proliferation in SIK2/3-overexpressing tumor cells. GRN-300 may enhance tumor
sensitivity to other chemotherapeutic agents. SIK2/3, serine/threonine centrosome
kinase family members required for bipolar mitotic spindle formation, are overexpressed
in a variety of tumor cell types.;
Molecule name : ARN 3261; ARN-3261; GRN-300; GRN 300;
