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. 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.

Description

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.

IC50 & 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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
