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 Ki values of 4, 32 and 54 μM, respectively[1]. ML-9 (Free Base) induces autophagy by stimulating autophagosome formation and inhibiting their degradation[3].

In Vitro	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]. Cell Viability Assay[1] Cell Line: Neonatal rat ventricular myocytes (NRVM) cells Concentration: 0, 10, 50 and 100 μM Incubation Time: 0, 1, 4, 8 and 24 hours Result: Decreased cell viability at 50–100 μM concentration. Apoptosis Analysis[1] Cell Line: Neonatal rat ventricular myocytes (NRVM) cells Concentration: 50 μM Incubation Time: 0, 1, 4, 8 hours Result: Induced cardiomyocyte death through necrosis and apoptosis.
