KN-62
Chemical Name: 4-[(2S)-2-[(5-isoquinolinylsulfonyl)methylamino]-3-oxo-3-(4-phenyl-1-piperazinyl)propyl] phenyl isoquinolinesulfonic acid ester
Purity: ≥98%
Biological Activity
KN-62 is a selective, cell-permeable inhibitor of CaM kinase II (IC50 = 0.9 μM). Binds directly to the calmodulin binding site of the enzyme. Potent non-competitive antagonist at the P2X7 receptor (IC50 = 15 nM).Technical Data
