Several 7 alpha-substituted 4-androstene-3,17-diones are potent inhibitors of the biosynthesis of estrogens, with the most effective being 7 alpha-(4'-amino)phenylthio-4-androstene-3,17-dione. An azide derivative of this 7 alpha-thioether compound has been prepared as a potential photoaffinity inhibitor. The enzyme kinetics of the azide analog were examined under both dark conditions and UV irradiation. In the dark, the azide was a very potent competitive inhibitor, with an apparent Ki of 1.3 nM. Under UV-irradiation, a time-dependent loss of aromatase activity was also observed. These studies indicate that the 7 alpha-substituent enhances the affinity of the steroidal analogs for the enzyme site.
The invention describes a combination of at least one aromatase inhibitor selected from the group of chemical-synthetic aromatase inhibitors and aromatase inhibition exhibiting extracts of soya beans and rapeseed, respectively, and at least one plant extract that contains one or more active ingredient substance(s) extracted from the plant, which is(are) selected from the group of 5α reductase type I and/or type II inhibitors and androgen receptor blockers, said combination being contained for example in a composition and having special properties for influencing hair growth. Uses of this combination are also described.
