ERp72 Inhibitors

Chemical Class Description: The class of ERp72 inhibitors encompasses a range of compounds that indirectly modulate the activity of ERp72 by targeting various components of the protein folding machinery and ER stress response pathways. These compounds do not interact directly with ERp72 but influence the cellular environment and mechanisms crucial for ERp72's role in protein disulfide isomerase activity. Tunicamycin, Thapsigargin, and Brefeldin A affect protein glycosylation, ER calcium homeostasis, and ER-Golgi transport, respectively, potentially impacting the protein folding processes where ERp72 is involved. Reducing agents like Dithiothreitol and β-Mercaptoethanol can interfere with the formation and isomerization of disulfide bonds, a key function of ERp72. Phenylarsine Oxide and proteasome inhibitor MG132 might disrupt ERp72's enzymatic activity and cause protein accumulation in the ER, respectively. Chloroquine, by altering endosomal and lysosomal pH, and 17-AAG, as an HSP90 inhibitor, represent different mechanisms of potentially influencing ERp72's function in protein folding and stress response. Curcumin and Salubrinal, by modulating ER stress pathways, and Guanabenz, by attenuating ER stress, highlight diverse approaches to indirectly affecting ERp72's activity.
