生物活性
GSK621 is a direct AMPK activator that exhibits anti-leukemic (300 μM; MOLM-14, HL-60, OCI-AML3) and anti-glioma (Effec. conc. 10-100 μM; U87MG and U251MG) activity, while displaying little cytotoxicity toward normal hematopoietic progenitors, primary human astrocytes, or HCN-1a neuronal cells. When administered via intraperitoneal injection, GSK621 (30 mg/kg twice daily) is shown to reduce leukemia growth and significantly extend the survival of mice xenografted with MOLM-14 cells. AMPK activation by GSK621 leads to mTOR inhibition and Tetraspanin 8 (Tspan8) downregulation in glioma cells, while GSK621-induced cytotoxicity in acute myeloid leukemia (AML) cells is the result of synthetic lethality, where co-activation of AMPK and mTORC1 activates the eIF2a signaling pathway, which in turn triggers autophagic cell death.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
