Charting New Territory: Systematic Evaluation of the Drug Potential of N -Trifluoromethyl Amides, Ureas & Carbamates

High Resolution Image Download MS PowerPoint Slide Amides and trifluoromethyl groups are among the most widely used structural motifs in materials science, medicinal chemistry, and agrochemistry. In contrast, their direct combination as N -trifluoromethyl amides and the closely related N -trifluoromethyl carbamates and ureas has remained largely unexplored. This disconnect has primarily stemmed from the lack of synthetic methods and their unknown stabilities and physicochemical properties. Enabled by recently developed methodologies to synthesize N -trifluoromethyl carbonyl compounds, we systematically evaluated their aqueous stability and drug-relevant properties to assess their usefulness for compound optimization. All investigated N -trifluoromethyl derivatives display high aqueous stability at pH 7.4, including in human plasma, except for one N -trifluoromethyl carbamate series. N -Trifluoromethyl carbonyl motifs have a lipophilicity and Caco-2 permeability similar to their N -isopropyl analogues, while, in several cases, offering improved pharmacokinetic profiles. These findings establish N -trifluoromethyl carbonyl motifs as highly attractive functionalities, providing medicinal chemists with a framework for their incorporation into future drug-discovery programs.
