TX-1918

A cell-permeable arylidene-cyclopentenedione derived tyrphostin that acts as a potent inhibitor for eEF2-K (IC₅₀ = 440 nM), while it inhibits other kinases at much higher concentrations (IC₅₀ = 4.4, 44, 44, and 440 µM for Src, PKA, PKC, and EGFR-K, respectively). Displays potent antitumor activity (EC₅₀ = 2.07 and 230 µM in HepG2 and HCT116 tumor cells, respectively) with greatly reduced mitochondrial- (≥5000-fold) and hepato-toxicity (≥90-fold) when compared with another tyrphostin, AG 17 (Cat. No. 658425). It is therefore a more promising candidate as a therapeutic agent for cancer treatment.
