  Oxidation of Dihydrotestosterone by Human Cytochromes P450 19A1 and 3A4

  摘要：

  Dihydrotestosterone is a more potent androgen than testosterone and plays an important role in endocrine function. We demonstrated that, like testosterone, dihydrotestosterone can be oxidized by human cytochrome P450 (P450) 19A1, the steroid aromatase. The products identified include the 19-hydroxy- and 19-oxo derivatives and the resulting Delta(1,10)-, Delta(5,10)-, and Delta(9,10)-dehydro 19-norsteroid products (loss of 19-methyl group). The overall catalytic efficiency of oxidation was similar to 10-fold higher than reported for 3 alpha-reduction by 3 alpha-hydroxysteroid dehydrogenase, the major enzyme known to deactivate dihydrotestosterone. These and other studies demonstrate the flexibility of P450 19A1 in removing the 1- and 2-hydrogens from 19-norsteroids, the 2-hydrogen from estrone, and (in this case) the 1-, 5 beta-, and 9 beta-hydrogens of dihydrotestosterone. Incubation of dihydrotestosterone with human liver microsomes and NADPH yielded the 18- and 19-hydroxy products plus the Delta(1,10)-dehydro 19-nor product identified in the P450 19A1 reaction. The 18- and 19-hydroxylation reactions were attributed to P450 3A4, and 18- and 19-hydroxydihydrotestosterone were identified in human plasma and urine samples. The change in the pucker of the A ring caused by reduction of the Delta(4,5) bond is remarkable in shifting the course of hydroxylation from the 6 beta-, 2 beta-, 1 beta-, and 15 beta-methylene carbons (testosterone) to the axial methyl groups (18, 19) in dihydrotestosterone and demonstrates the sensitivity of P450 3A4, even with its large active site, to small changes in substrate structure.

  A number of hitherto undescribed Δ2- and Δ3-3-deoxy-5α-androgen derivatives (17β,19-diols 12 and 13, 19-hydroxy-17-ketones 16 and 17, 19-oxo-17-ketones 18 and 19) were synthesized in good yield. The lithium-ammonia reduction of 19-(tetrahydropyran-2-yloxy)androst-4-ene-3, 17-dione 7 followed by Shapiro reaction allowed easy construction of both Δ2- and Δ3-3-deoxy-5α-steroid systems.
