How to use

In Vitro:

GSK621 (30 μM) induces AMPKα T172, ACC (S79) and ULK1 (S555) phosphorylation. GSK621 (30 μM) induces autophagy and apoptosis. GSK621 treatment also induces PERK phosphorylation, a marker of ER stress, in AML cells.

In Vivo:

GSK621 (30 mg/kg, ip twice daily) exhibits significant anti-tumor activity in MOLM-14 cells xenograft.
