VER-155008 is an ATP/adenosine analogue and a competitive Heat shock protein 70 (Hsp70) inhibitor with IC50 of 0.5 uM. It destabilizes oncoproteins, including Raf-1, Her-2, in several cancer cell lines. VER-155008 activates caspase-dependent and independent apoptosis in colon cancer cells. Selectivity for Hsp70 is uncertain as it has been found to bind Hsc70, Grp78, and Hsp90β.
