C₂₀H₂₄O₃

312.40

A cell-permeable, reversible and substrate-competitive arylidene-cyclopentenedione derived tyrphostin that acts as a kinase inhibitor for Src, eEF2-K, and PKA (IC₅₀ = 2.2, 3.2, and 9.6 µM, respectively). Inhibits EGFR-K and PKC only at much higher concentrations (IC₅₀ = 320 µM). Reported to exhibit potent anti-tumor activity (EC₅₀ = 3.66 and 39 µM in HepG2 and HCT116 tumor cells, respectively) with greatly reduced mitochondrial- (≥1000-fold) and hepato-toxicity (≥50-fold) when compared with another tyrphostin, AG 17 (Cat. No. 658425). May be useful as a therapeutic agent for cancer treatment in animal models.

No. 658425). It is therefore a more promising candidate as a therapeutic agent for cancer treatment.
