An extracellular peroxygenase of Agrocybe aegerita catalyzed the H(2)O(2)-dependent hydroxylation of the multi-function beta-adrenergic blocker propranolol (1-naphthalen-1-yloxy-3-(propan-2-ylamino)propan-2-ol) and the non-steroidal anti-inflammatory drug diclofenac (2-[2-[(2,6-dichlorophenyl)amino]phenyl]acetic acid) to give the human drug metabolites 5-hydroxypropranolol (5-OHP) and 4'-hydroxydiclofenac (4'-OHD). The reactions proceeded regioselectively with high isomeric purity and gave the desired 5-OHP and 4'-OHD in yields up to 20% and 65%, respectively. (18)O-labeling experiments showed that the phenolic hydroxyl groups in 5-OHP and 4'-OHD originated from H(2)O(2), which establishes that the reaction is mechanistically a peroxygenation. Our results raise the possibility that fungal peroxygenases may be useful for versatile, cost-effective, and scalable syntheses of drug metabolites.
