ML-9 Free Base 

ML-9 (Free Base) is a selective and potent inhibitor of Akt kinase, inhibits myosin light-chain kinase (MLCK) and stromal interaction molecule 1 (STIM1) activity^[3]. ML-9 (Free Base) inhibits inhibits MLCK, PKA and PKC activity with K_i values of 4, 32 and 54 μM, respectively^[1]. ML-9 (Free Base) induces autophagy by stimulating autophagosome formation and inhibiting their degradation^[3].

ML9 (Free Base) (0-100 μM; 0-24 hours) has no reduction in cardiomyocyte viability, 50-100 μM significantly induces cell death^[2].
ML9 (Free Base) (50 μM; 1-4 hours) significantly increases cleaved caspase-3 levels, decreased STIM1 protein levels by about 42%^[2].

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