Abstract

The controversial bioisosterism of the trifluoromethyl group has been re-assessed by measuring the inhibitory potency of a set of barbiturates having CF3, CH3, CH3CH2, and (CH3)2CH groups as remote substituents occupying the bottom of the tight lipophilic tunnel-like S1' pocket of collagenase B as a steric probe. The results support the recent hypothesis that the CF3 group is, in terms of bioisosterism, “smaller” than the isopropyl, larger than the methyl, and rather similar to the ethyl group.
