Description: 8-Chloroadenosine, also known as NSC-354258 and 8-Cl-Ado, is an 5' AMP-activated protein kinase (AMPK) agonist potentially for the treatment of chronic lymphocytic leukemia. 8-Chloroadenosine has shown to deplete ATP and inhibit tumor growth in hematological malignancies as well as in lung and breast cancer cell lines. 8-chloroadenosine activity is associated with inhibition of the mTOR pathway, and that phospho RPS6 and PI3K pathway activation status may determine resistance.
