Highly effective dipeptidic decoy molecules, which stimulate the direct hydroxylation of benzene by wild-type cytochrome P450BM3, were successfully developed through a rationally designed screening method. Extensive synthesis and step-wise screening of over 600 dipeptide derivatives were performed for the efficient evolution of decoy molecules. In the presence ofN-(3-cyclopentyl)propanoyl-l-pipecolyl-l-phenylalanine (3CPPA-Pip-Phe), one of the most effective decoy molecules discovered herein, the catalytic turnover frequency and total turnover number for benzene hydroxylation reached 405 min–1P450BM3–1and 54,500 P450BM3–1, respectively. Furthermore, the decoy molecules developed in this work drastically accelerated the hydroxylation of other non-native substrates, such as anisole and toluene, as well as nonaromatic compounds, such as cyclohexane, propane, and ethane. UsingN-enanthoyl-l-pipecolyl-l-phenylalanine (C7AM-Pip-Phe), the hydroxylation rate for ethane to ethanol reached 82.7 min–1P450BM3–1.
