ML228 (CID-46742353) is a potent the Hypoxia Inducible Factor (HIF) pathway activator with EC₅₀ of 1 μM. ML228 potently activates HIF in vitro as well as its downstream target VEGF^[1][2].

EC50: 1 μM (HIF)^[1]

ML228 (CID-46742353) represents a novel chemotype available to the research community for the study of HIF activation and its therapeutic potential. Not only is the compound substantially different in structure from known HIF activators, ML228 lacks the acidic functional group almost universally present in PHD inhibitors, which may be important for certain disease applications^[1][2].
