grp78-in-3

GRP78-IN-3, a potent small-molecule-competitive inhibitor of Hsp70 substrate binding and is a selective Grp78 (HSPA5) inhibitor with an IC50 of 0.59 μM. GRP78-IN-3 is 7-fold selective for HspA5 compared to HspA9 (IC50 of 4.3 μM) and >20-fold selective for HspA5 compared to HspA2 (IC50 of 13.9 μM).

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].
