We have modelled, using two approaches, a range of VE analogues into the proximal UbQ (Q(P)) binding site of CII. This study reveals that in both cases, the calculated interaction energies of individual VE analogues correlate (R(2) value >0.8) with their toxicity to cancer cells. These data further support the UbQ site(s) of CII as an important target determining the anti-cancer activity of VE analogues as well as other emerging anti-cancer drugs.
