AMPK Signaling Activator XIII, ZLN005

A cell-permeable benzimidazole that, in addition to its inhibitory potency against luciferase activity (IC₅₀<10 nM), also activates AMPK signaling by increasing cellular ADP/ATP ratio via mitochondria respiration upcoupling, effectively activating AMPK & PGC-1α in muscle, but not liver, cell types both in cultures (5-20 µM in rat L6 myotubes) in vitro and in db/db mice (15 mg/kg/day via p.o.) in vivo. Reported to improve glucose and insulin tolerance of db/db mice without any apparent effects on body weight or food intake.

A cell-permeable benzimidazole that, in addition to its inhibitory potency against luciferase activity (IC₅₀<10 nM), is reported to activate AMPK signaling by increasing cellular ADP/ATP ratio via mitochondria respiration uncoupling in a cell type-specific manner, effectively activating AMPK & PGC-1α in muscle, but not liver, cell types both in cultures (5-20 µM & 1-24 h in rat L6 myotubes; no effect in primary rat hepatocytes) in vitro and in db/db mice (gastrocnemius/calf muscle, but not liver tissue; 15 mg/kg/day via p.o. for 6 wks) in vivo. ZLN005 is orally available in mice (plasma C_max & T_max = 3.7 µM & 15 min, respectively, following single 15 mg/kg oral dosage to db/db mice) and is efficacious in improving glucose (1.5 g/kg i.p.) tolerance among 4-wk-treated and insulin (1 unit/kg) tolerance among 5-wk treated db/db mice (by 14% and 18%, respectively; 15 mg/kg/day via p.o.) in vivo without any apparent effects on body weight or food intake among db/db or non-diabetic controls.
