Significance

Crizotinib (PF-02341066) is a cMet/ALK inhibitor that is in phase III clinical trials for the treatment of cancer. A key step in the synthesis is the asymmetric reduction of acetophenone A to (S)-B using an engineered ketoreductase from Lactobacillus sp. The engineered ketoreductase has reversed enantioselectivity compared with the wild-type enzymes. The reversed enantioselectivity was achieved by mutating the tyrosine residue at position 190 to a proline.
