Encounter with unexpected collagenase-1 selective inhibitor: switchover of inhibitor binding pocket induced by fluorine atom

Bioorg Med Chem Lett. 2002 Feb 25;12(4):581-4. doi: 10.1016/s0960-894x(01)00796-x.

Abstract

Phosphonamide-based inhibitors having trifluoromethyl moiety showed highly selective inhibition against MMP-1. A possible mechanism of the selectivity of MMP-1 inhibitors through the switchover of the binding pocket was speculated by computational calculations. As a consequence of the unexpected selectivity, the specific interaction of CF3 group of the inhibitor and Arg214 in the S1' pocket of MMP-1 conducted a low binding energy.
