Beschreibung

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 µM). Shown to be superior to PD 98059 (Cat. Nos. 513000 and 513001 and U0126 (Cat. No. 662005) in suppressing Erk1/2 phosphorylation in Hep3B, HepG2, PLC, and SKHep human liver cancer cells (IC₅₀<0.1 µM) 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.
