EX229 是一种 AMP 活化蛋白激酶 (AMPK) 的有效变构激动剂， 是苯并咪唑衍生物，其对 α1β1γ1、α2β1γ1 和 α1β2γ1 的Kd值分别为 0.06、0.06 和 0.51 μM。

EX229 is an allosteric activator of AMPK, with Kds of 0.06 μM, 0.06 μM and 0.51 μM for α1β1γ1, α2β1γ1, and α1β2γ1, respectively.

Treatment of hepatocytes with EX229 (991) alone results in a slight increase in the phosphorylation of AMPK and RAPTOR only at 0.3 μM, whereas a robust increase in ACC phosphorylation is readily observed and saturated at a concentration of 0.03 μM EX229. AICAR or C13 alone robustly increases T172 phosphorylation of AMPKα, and when 991 is coincubated, there is a modest additional dose-dependent increase in AMPKα phosphorylation. RAPTOR phosphorylation is modestly increased by AICAR or C13 alone, and it is dose-dependently increased when coincubation is carried out with EX229. EX229 also dose-dependently (0.01 and 0.1 μM) inhibits lipogenesis (34% and 63%, respectively), which is further reduced when it is coincubated with a low dose of AICAR (0.03 mM) or C13 (1 μM). Treatment with EX229 promotes dose-dependent increases in ACC and RAPTOR phosphorylation. Similar to the observations in hepatocytes [2].
