General description

A cell-permeable, blood-brain barrier permeant, and orally active hydroxamate compound that is reported to inhibit MEK activity (IC50 = 10-100 nM) without competing against ATP or Erk binding and exhibit excellent selectivity over 27 other cellular kinases, including JNK, MAPK2/ERK2, SAPK2a, SAPK2b, SAPK3, and SAPK4 (IC50 >10 M). Shown to be superior to PD 98059 and U0126 in suppressing Erk1/2 phosphorylation in Hep3B, HepG2, PLC, and SKHep human liver cancer cells (IC50<0.1 M) in vitro and effectively reduce Erk1/2 phosphorylation in hippocampal tissue in mice (ED50<50 mg/kg, i.p.) in vivo. Both PD184161 and U0126 are shown to induce necrosis of several types of glucose-deprived cells via an indirect action on the F0 component of the mitochondrial F1F0-ATPase/synthase.

The hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis caused by stress will inevitably disrupt the homeostasis of the neuroendocrine system and damage physiological functions. It has been demonstrated that electroacupuncture (EA) can modulate HPA axis hyperactivity during the perioperative period. As
