Definitions
- the invention relates to new Estra-1, 3,5 (10) -trien-3-yl sulfamates which, in the C 13 position, contain a C 2 -C 5 alkyl, C 2 -C alkenyl or C 2 - C 5 alkynyl and have an acyl, oxycarbonyl, aminocarbonyl, sulfonyl or aminosulfonyl radical on the nitrogen atom of the sulfamate group.
- the invention also relates to processes for the preparation of the compounds according to the invention and pharmaceutical compositions which contain these compounds.
- the compounds according to the invention have proven to be steroid sulfatase inhibitors which do not have an estrogenic effect.
- estrogens are primarily synthesized and secreted by the ovaries. Accordingly, in sexually mature women, the blood levels of estradiol, estrone and estrone sulfate fluctuate over the course of the cycle. In human pregnancy, the placenta secretes much higher amounts of estrogen than the ovary. In addition to these estrogen sources, peripheral estrogen sources play a role in the human organism, which are of primary importance when ovarian estrogen secretion has ceased or has not yet been established. These estrogen sources have also been shown to be of great physiological importance for the male sex.
- BEST ⁇ TIGUMGSKOPIE found that factor 50-300 times higher estrogen levels were generated in breast cancer via sulfatase activity (cleavage of estrone sulfate) than via aromatase (Pasqualini JR et al., Estrone sulfatase versus estrone sulfotransferase in human breast cancer: potential clinical applications. J. Steroid Biochem. And Mol. Biol. 69 (1999) 287-292). Similar findings were also made by other groups. In breast tissue, 10-fold more estrone is generated from androstenedione via sulfatase than from aromatase.
- sulfatase inhibitors can very effectively inhibit the growth of estrogen-dependent tumors, since they greatly reduce the estrogen concentration in the tumor tissue itself.
- sulfatase inhibitors are therefore increasingly being sought which are not themselves estrogenic and, as a result of the hydrolysis, do not give rise to any estrogenic products.
- 2-methoxy-estrone-3-O-sulfamate is a potent sulfatase inhibitor which has no estrogenic effect on uterine growth in ovariectomized rats.
- Estrone-3-O-sulfamates are also described as sulfatase inhibitors in WO 93/05064.
- the Estro ⁇ -3-O-sulfamate unsubstituted by nitrogen is a strong sulfatase inhibitor (cf. Horwarth et al. In J. Med. Chem. 1994, 37, pp. 219-221, in particular Fig. 3 on page 220).
- this substance also shows strong estrogenic effects as described by Elger W. et al. in J. Steroid Biochem. Mol. Biol. 55 (1995), pp. 395-403.
- Further estrone-3-O-sulfamates are disclosed as sulfatase inhibitors in WO 99/33858. These compounds have essentially no estrogenic activity.
- Sulfamoyloxy compounds with more than one sulfamate group in the molecule in particular those which are sulfamoylated at the positions characteristic of the estrogenic action, including substituents or side chains (e.g. in the 7- and / or 11-position), which can be located on the periphery of the steroid structure, a significant increase in Have sulfatase activity with reduced estrogenic activity.
- 3,17-disulfamoyloxydef ⁇ vate show good sulfatase activity.
- monosulfamates also have good sulfatase inhibition with low estrogenicity, with the exception of the ring A sulfamates.
- Ring A sulfamates are known from WO 97/14712 - as mentioned above - as compounds with a pronounced strong estrogenic action.
- the object of the present invention was to provide further steroid sulfatase inhibitors which themselves have no estrogenic action and which, as a result of the hydrolysis, do not give any estrogenic products.
