AMPK Activator, COH-SR4

A cell permeable, orally bioavailable bis(dichlorophenyl)urea that acts as an AMPK activator via possibly targeting upstream of AMPK. Shown to increase AMPK phosphorylation and activation in multiple preadipocytes and cancer cell lines dose-dependently. Inhibits glutathione S transferase (GST) activity and induces G2/M phase cell cycle arrest in multiple melanoma cells (IC₅₀ = 5-11 µM). Effectively inhibits tumor burden, decreases angiogenesis marker CD31 and proliferation marker Ki67, and increases pAMPK levels in vivo (4 mg/kg p.o., mouse) without obvious toxicity. Displays similar anti-cancer effects in lung cancer models both in vitro and in vivo. In addition, shown to down-regulate key proteins involved in fatty acid synthesis and inhibits adipocyte differentiation via AMPK activation in 3T3-L1 obesity model cells (IC₅₀ = ~1.5 µM).

AMPK Activator, COH-SR4, is a cell permeable AMPK activator that acts upstream of AMPK. Increases AMPK phosphorylation and activation in preadipocytes and cancer cell lines.
