Definitions
- the invention relates to 15 ⁇ ,16 ⁇ -methylene-17-hydroxy-19-nor-17-pregna-4-en-3-one-21-carboxylic acid ⁇ -lactone derivatives with progestational action, use thereof and medicinal products containing the derivatives, for example for the treatment of pre-, peri- and postmenopausal and of premenstrual complaints.
- WO 2006072467 A1 discloses the compound 6 ⁇ ,7 ⁇ -15 ⁇ ,16 ⁇ -dimethylene-3-oxo-17-pregn-4-ene-21,17 ⁇ -carbolactone (drospirenone), which has progestational action and has been used for example in an oral contraceptive and in a preparation for the treatment of postmenopausal complaints. Owing to its comparatively low affinity for the progestogen receptor and its comparatively high ovulation-inhibiting dose, however, drospirenone is contained in the contraceptive at the relatively high daily dose of 3 mg.
- Drospirenone is, moreover, also characterized in that in addition to the progestational action it also has aldosterone-antagonistic (antimineralocorticoid) and antiandrogenic action. These two properties make drospirenone very similar in its pharmacological profile to the natural progestogen, progesterone, which however, unlike drospirenone, is not sufficiently bioavailable orally.
- WO 2006072467 A1 further proposes an 18-methyl-19-nor-17-pregn-4-ene-21,17-carbolactone and pharmaceutical preparations containing this, which have a higher progestational potency than drospirenone.
- U.S. Pat. No. 3,705,179 discloses steroids that display antiandrogenic activity and are suitable for the treatment of diseases that are linked to androgens.
- the aim of the present invention is to make compounds available that bind strongly, and preferably more strongly than drospirenone, to the progestogen receptor. Moreover, the compounds should preferably also have antimineralocorticoid action and, with respect to the androgen receptor, a neutral to slightly androgenic action.
- Another essential aim of the present invention consists of achieving a balanced action profile with respect to the progestational action to the antimineralocorticoid action, so that the ratio of the progestational action to the antimineralocorticoid action is less than with drospirenone.
- the present invention describes the novel 15,16-methylene-17-hydroxy-19-nor-17-pregna-4,20(Z)-dien-3-one-21-carboxylic acid ⁇ -lactone derivatives of general formula I,

- the numbering of the carbon backbone of the derivatives according to the invention with the general chemical formula I follows the numbering of a steroid structure in the usual way, as described for example in Fresenius, loc. cit.
- the numbering of the residues stated in the claims corresponds in a similar manner to their bonding position on the carbon backbone of the derivative, as far as this relates to R 4 , R 6 , R 7 and R 18 .
- the residue R 4 binds to the C 4 -position of the derivative according to the invention.

Furthermore, some interesting compounds according to the invention interact with the mineralocorticoid receptor and are able to impart an antagonistic action. Moreover, the compounds according to the invention have a neutral to slightly androgenic action with respect to the androgen receptor. Another property of the compounds is that the bonds of these compounds to the progesterone receptor and to the mineralocorticoid receptor are balanced relative to one another, namely so that the ratio of their capacity for binding to the progesterone receptor to the capacity for binding to the mineralocorticoid receptor is less than in the case of drospirenone.
- the antimineralocorticoid action of these compounds at given progestational action is less than with drospirenone. If the dosage of a given compound according to the invention is based on its progestational action, the antimineralocorticoid action of this compound at this dosage is therefore less than with drospirenone.
