2-(2,4-dioxo-1,3-thiazolidin-5-yl)-N-(2-hydroxyphenyl)acetamide
-
inhibitor is about 1000times more selective for isoform AKR1C3 over AKR1C2, and selectivity is even higher when compared with AKR1C1 and AKR1C4
2-[[(3-hydroxyphenyl)carbonyl]amino]-4,5-dimethoxybenzoic acid

3-((4-nitronaphthalen-1-yl)amino)benzoic acid
-
inhibitor nanomolar potency and selective inhibition of isoform AKR1C3 but also acts as an androgen receptor antagonist. It inhibits 5alpha-dihydrotestosterone stimulated androgen receptor reporter gene activity with an IC50 value of 4.7 microM and produces a concentration dependent reduction in androgen receptor levels in prostate cancer cells
3-phenoxybenzoic acid
-
inhibitor carboxylic acid binds to the oxyanion site, in which the carboxylate group very closely overlays the acetate molecule found in other AKR1C3 structures and forms hydrogen bonds to the enzyme catalytic residues His117 and Tyr55, as well as to a conserved water network located in and near the SP3 subpocket. The 3-phenoxy ring extends into the SP1 subpocket and makes van der Waals contacts with the aromatic residues Phe306, Phe311 and Tyr319 that line the pocket
