1.1.1.213 3alpha-hydroxysteroid 3-dehydrogenase (Re-specific)IUBMB Comments
The enzyme acts on multiple 3alpha-hydroxysteroids. Re-specific with respect to NAD+ or NADP+ [cf. EC 1.1.1.50, 3alpha-hydroxysteroid 3-dehydrogenase (Si-specific)]. Enzymes whose stereo-specificity with respect to NAD+ or NADP+ is not known are described by EC 1.1.1.357, 3alpha-hydroxysteroid 3-dehydrogenase.

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
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
3-[(4-nitrophenyl)amino]benzoic acid
94fold selectivity for the inhibition of isoform AKR1C3 over AKR1C2

malfunction
comparison of a common non-synonymous polymorphism, AKR1C3-2 in the gene encoding the enzyme 3alpha-HSD2/17beta-HSD5 and a synonymous SNP, rs248793, in SRD5A1, which encodes 5alpha-reductase: for caucasian males, carriers of the alcohol dependence-protective AK1C3-2 G-allele have higher levels of 5alpha-androstane-3alpha1beta-diol relative to the precursor 3alpha,5alpha-androsterone than C-allele homozygotes. AKR1C3-2 G-allele carriers exhibit greater increases in heart rate and stimulant and sedative effects of alcohol than C-allele homozygotes
physiological function
physiological function
exposure of HCT-15 cells to cisplatin results in aquisition of cisplatin resistance and concomitant induction of isoform AKR1C3 and aldo-keto reductase AKR1C1 expression. The resistance lowers the sensitivity toward cellular damages evoked by oxidative stress-derived aldehydes, 4-hydroxy-2-nonenal and 4-oxo-2-nonenal that are detoxified by AKR1C1 and AKR1C3. Overexpression of AKR1C1 or AKR1C3 in the parental HCT15 cells mitigates the cytotoxicity of the aldehydes and cisplatin. Knockdown of both AKR1C1 and AKR1C3 in the resistant cells or treatment of the cells with specific inhibitors of the aldo-keto reductases increases the sensitivity to ciplatin toxicity
physiological function
in LNCaP and LNCaP-AKR1C3 cells overexpressing isoform AKR1C3, metabolism proceeds via 5alpha-reduction to form 5alpha-androstane-3,17-dione and then (epi)androsterone-3-glucuronide. LNCaP-AKR1C3 cells make significantly higher amounts of testosterone-17beta-glucuronide. When 5alpha-reductase is inhibited by finasteride, the production of testosterone-17beta-glucuronide is further elevated in LNCaP-AKR1C3 cells. When AKR1C3 activity is inhibited with indomethacin the production of testosterone-17beta-glucuronide is significantly decreased. 4-Androstene-3,17-dione treatment stimulates cell proliferation in both cell lines. LNCaP-AKR1C3 cells are resistant to the growth inhibitory properties of finasteride, consistent with the diversion of 4-androstene-3,17-dione metabolism from 5alpha-reduced androgens to increased formation of testosterone
physiological function
the enzyme 3alpha-hydroxysteroid dehydrogenase is involved in neuroactive steroid biosynthesis. Genetic variation in a region of chromosome 10 containing the genes AKR1C1, AKR1C3 and AKR1C4, which encode 3 isoforms of 3alpha-HSD, is associated with variation in subjective alcohol response. Enzyme mutant variant H5Q is associated with reduced risk of both alcohol dependence and bladder cancer, moderates the stimulant or sedative effects of alcohol

10 ns molecular dynamics simulations of inhibitor bound to isofrom AKR1C3. Binding could induce conformational changes to both inhibitor and enzyme. The compound presumably assumes a stable, energetically favored, planar conformation, with an estimated free energy of binding of -5 kcal/mol
docking of inhibitors (2E)-3-(4-methylphenyl)-2-[4-(methylsulfonyl)phenyl]prop-2-enoic acid, (2E)-3-(4-ethylphenyl)-2-[4-(methylsulfonyl)phenyl]prop-2-enoic acid, (2E)-3-(4-bromophenyl)-2-[4-(methylsulfonyl)phenyl]prop-2-enoic acid and (2E)-3-[4-(methylsulfanyl)phenyl]-2-[4-(methylsulfonyl)phenyl]prop-2-enoic acid to crystal structure. Compounds occupy a similar position of the active site as the co-crystallized indomethacin, with the Aryl1 overlapping with the p-chlorobenzoyl moiety of the indomethacin and the Aryl2 overlapping with an indole part of the indomethacin

in complex with inhibitor 3-[[4-(trifluoromethyl)phenyl]amino]benzoic acid. Compound adopts a similar binding orientation as flufenamic acid, however, its phenylamino ring projects deeper into a subpocket and confers selectivity over the other AKR1C isoforms
