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]. JH295 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
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].
