PDGFRA/CAIX/XII-IN-1

PDGFRA/CAIX/XII-IN-1 is a multi-target inhibitor targeting PDGFRA, CA IX and CA XII, with an IC50 of 20 nM against PDGFRA and Ki values of 93.3 nM and 80.0 nM against CA IX and CA XII respectively. It targets and binds to the ATP-binding pocket of PDGFRA, thereby blocking the activation of downstream signaling pathways such as STAT3, AKT and ERK1/2. It induces G0/G1 phase cell cycle arrest and initiates endogenous apoptotic procedures, manifested as cleavage and activation of PARP-1, caspase-9 and caspase-3, upregulation of caspase 3/7 activity and inhibition of Mcl-1 protein expression. It exerts significant anti-proliferative effects in eosinophilic leukemia cells and can serve as a candidate tool compound for mechanism and efficacy research of leukemia.
