AP-4-139B is a potent inhibitor of HSP70, exhibiting an IC50 of 180 nM against human HSP70. Its mechanism involves direct binding to HSP70, leading to the inhibition of ATPase activity. By facilitating the phosphorylation of Beclin-1, AP-4-139B promotes autophagy. This compound has demonstrated significant antitumor activity in preclinical models of colorectal cancer and pancreatic ductal adenocarcinoma, making it a valuable tool for cancer research.
