Eukaryotic elongation factor 2 (eEF-2) kinase (CaMK III) inhibitor (IC50 = 60 nM) that displays 125-fold, > 1300-fold and > 1500-fold selectivity over PKC, PKA and CaMK II respectively. Decreases the viability of a variety of cancer cell lines (IC50 values are 0.7 - 4.8 μM) and blocks G1/S cell cycle progression. Shown to induce eEF-2 phosphorylation in cancer cells. Also an effective antibacterial agent; inhibits histidine protein kinase in vitro (IC50 = 6.6 μM) and in vivo.
