title: Inhibition of 3(17)alpha-hydroxysteroid dehydrogenase (AKR1C21) by aldose reductase inhibitors.
abstract: Mouse 3(17)alpha-hydroxysteroid dehydrogenase (AKR1C21) is a member of the aldo-keto reductase superfamily that catalyses the oxido-reduction of steroid hormones such as estrogens, androgens and neurosteroids. Inhibitors of aldose reductase (AR), a member of the same superfamily, were evaluated against AKR1C21. Models of the enzyme-inhibitor complexes suggest that Tyr118 and Phe311 are important residues for inhibitor recognition and orientation in the active site of AKR1C21.
