HM03 trihydrochloride, a potent and selective inhibitor of HSPA5 (also known as Bip or Grp78), exhibits anticancer activity.

Sodium palmitate-13C is the 13C-labeled variant of palmitic acid, a long-chain saturated fatty acid prevalent in animals and plants. This compound has been shown to induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP) in mouse granulosa cells.

Palmitic acid-13C16 sodium, a 13C-labeled form of the naturally occurring saturated fatty acid Palmitic acid sodium, is prevalent in animals and plants. This compound can trigger the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in mouse granulosa cells.

Palmitic acid-13C2 is the 13C-labeled Palmitic acid. Palmitic acid is a long-chain saturated fatty acid commonly found in both animals and plants. Palmitic acid can induce the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in in mouse granulosa cells.

BOLD-100 free base (NKP-1339; IT-139), a ruthenium-based anticancer agent, inhibits stress-induced GRP78 upregulation, thus disrupting endoplasmic reticulum (ER) homeostasis. This action induces ER stress and unfolded protein response (UPR), interfering with the intricate relationship between ER-stress response, lysosome dynamics, and autophagy execution.

Calcium palmitate, a long-chain saturated fatty acid prevalent in animals and plants, induces the expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in mouse granulosa cells. It is employed to establish a cell steatosis model [1] [2].

1,2-Dipalmitoyl-3-Octanoyl-rac-glycerol, a triacylglycerol, has palmitic acid at its sn-1 and sn-2 positions, and octanoic acid at the sn-3 position. Palmitic acid, a long-chain saturated fatty acid found in both animals and plants, can induce glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) expression in mouse granulosa cells. Octanoic acid, an oily liquid with a slightly unpleasant rancid taste, is utilized in ester production for perfumery, dye manufacturing, and also serves as a tremor-suppressing agent [1] [2] [3] [4].

Neoisoliquiritigenin, isolated from Spatholobus suberectus, inhibits cell proliferation and induces cell apoptosis in breast cancer by directly binding to GRP78 to regulate the β-catenin pathway
