ACA-28
ACA-28 (compound 2a) is a potent modulator of the ERK MAPK signaling pathway that exerts anticancer effects through a unique mechanism involving ERK hyperactivation. Rather than inhibiting ERK activity directly, ACA-28 induces sustained ERK activation, which paradoxically triggers apoptosis in cancer cells. It demonstrates selective cytotoxicity, inhibiting the growth of melanoma cells (SK-MEL-28) with an IC₅₀ of 5.3 μM, while showing lower toxicity toward normal human melanocytes (NHEM), with an IC₅₀ of 10.1 μM. ACA-28's ability to exploit ERK signaling dysregulation for selective induction of apoptosis makes it a promising candidate for further development in cancer therapy, particularly in ERK-dependent malignancies.
