Description: YUM70 is a potent inhibitor of GRP78 (Glucose-regulated protein, 78 kDa). YUM70, inhibited pancreatic cancer cell growth in vitro and showed in vivo efficacy in a pancreatic cancer xenograft model with no toxicity to normal tissues. YUM70 directly bound GRP78 and inactivated its function, resulting in ER stress-mediated apoptosis. A YUM70 analog conjugated with BODIPY show co-localization of the compound with GRP78 in the ER. Moreover, a YUM70-PROTAC (PROteolysis TArgeting Chimera) was synthesized to force degradation of GRP78 in pancreatic cancer cells. YUM70 showed a strong synergistic cytotoxicity with topotecan and vorinostat.

Additional Information

GRP78 (Glucose-regulated protein, 78 kDa) is a key regulator of ER (endoplasmic reticulum) stress signaling. Cancer cells are highly proliferative and have high demand for protein synthesis and folding, which results in significant stress on the ER. To respond to ER stress and maintain cellular homeostasis, cells activate the unfolded protein response (UPR) that promotes either survival or apoptotic death. Cancer cells utilize the UPR to promote survival and growth
