K-252a, Nocardiopsis sp.

Primary Target
CaM kinase II

Target K_i: 1.8 nM, 20 nM, 18 nM, 25 nM, 20 nM, 3 nM, against CaM kinase II, myosin light chain kinase, protein kinase A, protein kinase C, protein kinase G, NGF receptor gp140trk, respectively

Toxicity: Standard Handling (A)

A cell-permeable, reversible, and ATP-competitive inhibitor against multiple protein kinases, including, but not limited to, CaM kinase II (K_i = 1.8 nM), myosin light chain kinase (K_i = 20 nM), protein kinase A (K_i = 18 nM), protein kinase C (K_i = 25 nM), protein kinase G (K_i = 20 nM), NGF receptor gp140^trk (IC₅₀ = 3 nM), its transforming trk oncogenes, and the related neurotrophin receptors gp145^trkB and gp145^trkC. Reported to induce apoptosis and cell cycle arrest by decreasing Cdk1 and Cdc25c activity in T98G cells and inhibit Flt3 phosphorylation in Flt3/Itd-BaF3 cells (IC₅₀<50 nM). Also available as a premade 1 mM (100 µg/214 µl) solution in DMSO (Cat. No. 420297).
