ARN-3236 is an oral active and selective inhibitor of salt-inducible kinase 2 (SIK2), (SIK2, SIK1 and SIK3 with IC50s of <1 nM, 21.63 nM and 6.63 nM respectively). ARN-3236 Has anti-cancer activity.

SIK2:<1 nM , SIK3:6.63.nM, SIK1:21.63 nM

SIK2 expression was determined in ovarian cancer tissue samples and cell lines.?ARN-3236 was tested for its efficiency to inhibit growth and enhance paclitaxel sensitivity in cultures and xenografts of ovarian cancer cell lines.?SIK2 siRNA and ARN-3236 were compared for their ability to produce nuclear-centrosome dissociation, inhibit centrosome splitting, block mitotic progression, induce tetraploidy, trigger apoptotic cell death and reduce AKT/survivin signaling.
