GSK621 是特异性的 AMPK 激动剂，其对 AML 细胞系的IC50 值为13-30 μM。GSK621 可诱导自噬和凋亡。GSK621 可诱导eiF2α 磷酸化 (UPR 激活的一个标志)。 Information GSK621 GSK621 is a specific and potent AMPK activator. Targets AMPK (Cell-free assay) In vitro In AML cell lines and primary AML samples, GSK621 markedly increases phosphorylation at AMPKα T172, a marker of AMPK activation. In a set of 20 cell lines, GSK621 reduces the proliferation of all 20 lines with IC50 ranged from 13-30 μM, and increases apoptosis in 17 (85%) lines. In addition, GSK621 also triggers autophagy, which partially contributes to AML cell death. In vivo In nude mice bearing MOLM-14 xenografts, GSK621 (30 mg/kg, i.p.) reduces leukemia growth and significantly extends survival by enhancing AMPK activity and the induction of apoptosis.
