TRAP1 Inhibitors

Chemical inhibitors of TRAP1 include a range of compounds that interact with the protein in various ways to inhibit its function. Gamitrinib binds directly to TRAP1, disrupting its chaperone activity crucial for protein folding and stabilization, which is essential for maintaining mitochondrial integrity and regulating apoptosis. Similarly, Shepherdin competes with ATP for binding to TRAP1, thus preventing the protein from performing its chaperone functions necessary for its protective roles against cellular stress. HS-72 takes a comparable approach by directly interacting with TRAP1, inhibiting its ATPase activity, which is foundational for its chaperone function, further impacting TRAP1's role in mitochondrial homeostasis and apoptosis prevention.

The inhibition of TRAP1 can also be achieved with metal-containing compounds such as KP1339, which binds to the protein and inhibits its chaperone activity, disrupting its ability to protect cells from oxidative stress. Hsp90 inhibitors like MPC-3100, BIIB021, NVP-AUY922, SNX-2112, 17-DMAG, and PU-H71 are particularly effective against TRAP1 due to its close relationship with the Hsp90 family of proteins. These compounds bind to TRAP1, inhibiting its chaperone activity, which is central to the protein's role in mitochondrial signaling, apoptosis, and cellular stress response. By targeting these specific biochemical pathways, these inhibitors can effectively diminish TRAP1's function within the cell.
