VER 155008 is a novel adenosine-derived inhibitor of Heat Shock Protein 70 (Hsp70) (IC50 = 0.5 μM). Inhibits cell proliferation of multiple human tumor cell lines in vitro. Also binds Hsc70 and Grp78; displays selectivity against Hsp90β (IC50 >200 μM for Hsp90β).
VER 155008 is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.

Used this and apoptozole to knock down HSP70 expression. We ended up using Apoptozole for our work but this also worked well. Easy to reconstitute and found to be stable. Confirmed K.D. using qPCR, WB, and IF.
Cytotoxic to microglia at higher dosages (>1uM) observed using a cell viability assay and cell imaging.
Human osteosarcoma, U2OS, cells were incubated with VER 155008 (1 microM) for 24 h to follow PARP cleavage using Western blot. Hsp70 inhibition with VER 155008 significantly induced PARP cleavage in U2OS cells.
