Description
JG-98, an allosteric heat shock protein 70 (Hsp70) inhibitor, which binds tightly to a conserved site on Hsp70 and disrupts the Hsp70-Bag3 interaction. JG-98 shows anti-cancer activities affecting both cancer cells and tumor-associated macrophages.

How to use
In Vitro:
JG-98 (30 nM-30 μM; 72 hours) has antiproliferative activity across a range of cell lines with the EC50s between ~0.3 and 4 μM. JG-98 (10 μM; 48 hours) activates apoptotic mediators (cleavage of caspase-3 and PARP) in MDA-MB-231 cells. JG-98 destabilizes FoxM1 and relieves suppression of downstream effectors, including p21 and p27.
In Vivo:
JG-98 (3 mg/kg; i.p.; on days 0, 2, and 4) suppresses tumor growth in xenograft models bearing MCF7 and HeLa cells.
