JH295 is a potent, irreversible and selective NIMA-related kinase 2 (Nek2) inhibitor with an IC50 of 770 nM. JH295 inhibits cellular Nek2 via alkylation of Cys22. JH295 is inactive against the mitotic kinases, Cdk1, Aurora B or Plk1, and does not perturb bipolar spindle assembly or the spindle assembly checkpoint[1].

Target	IC50: 770 nM (Nek2)[1]
In Vitro	JH295 (Compound 16; 0.08-20 μM; 45 minutes; RPMI7951 cells) treatment inhibits WT Nek2 in cells with an IC50 of ~1.3 μM, whereas it has little effect on the C22V mutant[1]. Western Blot Analysis[1] Cell Line: RPMI7951 cells Concentration: 0.08 μM, 0.25 μM, 0.74 μM, 2.2 μM, 6.6 μM, 20 μM Incubation Time: 45 minutes Result: Inhibited WT Nek2 in cells with an IC50 of ~1.3 μM, whereas had little effect on the C22V mutant.
