ID: ALA3888494
Type: Binding
Description: Inhibition Assay: Inhibitors were initially screened for an ability to block the NADP+ dependent oxidation of the artificial substrate S-tetralol catalyzed by AKR1C3. S-tetralol was used since it is also a substrate of the highly related AKR1C1 and AKR1C2 enzymes. Inhibition of AKR1C1 and AKR1C2 is undesirable in the context of prostate cancer since they are involved in the elimination of DHT (see FIG. 1B; see also Rizner et al, 2003; Steckelbroeck et al. 2004). All assays were performed at Km so that IC50 values across enzyme forms were comparable.An exemplary screening strategy was against homogeneous recombinant AKR1C3 and its highly related enzyme AKR1C2 to generate full dose-response curves and IC50 values.
