Abstract
The present invention relates to sulfonyltryptophanols of the general formula I,
Description

The present invention relates to the use of sulfonyltryptophanols as FSH-receptor antagonists. The present invention also relates to novel sulfonyltryptophanols, process for their preparation, pharmaceutical compositions comprising the compounds according to the invention, their use for fertility control in men or women, and their use for the treatment and/or prevention of osteoporosis.


Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are together responsible for the control of male and female fertility and of the production of sex steroids.


In the female mammal, FSH controls the early ripening of ovarian primary follicles and the biosynthesis of sex steroids. In the advanced stage of differentiation (preantral follicles), the influence of LH becomes increasingly important for further development of the follicles until ovulation occurs.


In male mammals, FSH is primarily responsible for the differentiation and stimulation of Sertoli cells. Their function consists of assisting spermatogenesis on many levels. LH is primarily responsible for stimulating the Leydig cells and thus androgen production.


FSH, LH and TSH (thyrotropic hormone) together form the group of glycoprotein hormones which are formed in the pituitary and are secreted from there. Whereas the alpha subunit is common to the three hormones, their specificity of action is determined by the beta chain which is unique in each case. The molecular weight of FSH including the sugar portion is about 30 kD.


FSH and the other glycoprotein hormones act specifically via their selectively expressed G protein-coupled receptor (GPCR). FSH stimulates, through binding to its receptor, the association thereof with a stimulating G protein (Gs) which is thereby stimulated to hydrolyse guanosine triphosphate (GTP) and to activate the membrane-associated adenylate cyclase. Cyclic adenosine monophosphate (cAMP) is accordingly an important and readily quantifiable secondary messenger substance of FSH (G. Vassart, L. Pardo, S. Costagliola, Trends Biochem. Sci. 2004, 29, 119-126).


The importance of FSH for male fertility is the subject of intensive research. It has been possible to show that FSH influences several processes of spermatogenesis such as the proliferation of spermatogonia, the antiapoptotic effect on spermatogonia and spermatocytes and the stimulation of sperm maturation including motility thereof.


The following arguments are also in favour of the FSH receptor as target for male fertility control:

  • 1. The FSH receptor is exclusively expressed on Sertoli cells (high specificity).
  • 2. Contraceptive vaccination against FSH beta chain or the FSH receptor induces infertility in male primates (N. R. Mougdal, M. Jeyakumar, H. N. Krishnamurthy, S. Sridhar, H. Krishnamurthy, F. Martin, Human Reproduction Update 1997, 3, 335-346).
  • 3. Naturally occurring mutations in the FSH receptor or the FSH beta chain may lead to sub- or infertility in men (I. Huhtaniemi, Journal of Reproduction and Fertility 2000, 119, 173-186; L. C. Layman, P. G. McDonough, Molecular and Cellular Endocrinology 2000, 161, 9-17).
  • 4. Neutralizing FSH antiserum has no effect on testis weight and testosterone production (V. Sriraman, A. J. Rao, Molecular and Cellular Endocrionology 2004, 224, 73-82). Adverse effects of FSH blockade on androgen production therefore appear unlikely.


In line with these arguments, FSH antagonists are expected to be suitable for spermatogenesis inhibition (prevention) in men. Moreover, a suitable FSH antagonist may just as well lead to infertility in women, because it suppresses follicle ripening and thus also ovulation. On the other hand, the skilled person expects advantages from non-peptidergic FSH agonists when used to promote fertility in women (stimulation of follicle ripening). There are no reports of experience on the use of FSH or FSH agonists in male infertility, but specific indications are also conceivable in this connection.


New findings demonstrate that there is also a direct effect of FSH on cells of bone metabolism. There are two fundamentally different cell types in bones: osteoclasts and osteoblasts. While osteoclasts play a central role in bone resorption (breakdown of bone), osteoblasts simulate bone density (anabolic effect).


FSH receptors have been detected in osteoclasts but not in osteoblasts. In vitro, FSH stimulates bone resorption by mouse osteoclasts (Li Sun et al. Cell 2006; 125: 247-60). A clinical correlation between the height of the serum FSH levels and low bone density has been observed in postmenopausal women (Devleta et al, J. Bone Miner. Metab. 2004, 22: 360-4).


These findings among others suggest that FSH stimulates loss of bone mass, and accordingly FSH antagonists will display an antiresorptive effect on bone and are therefore suitable for the therapy and/or prevention of peri- and postmenopausal loss of bone mass and osteoporosis.


FSH receptor modulators are compounds that have a mixed profile of both FSH receptor antagonistic and/or FSH receptor agonistic properties. FSH receptor modulators of various compound classes of low molecular weight, have been reported on recently.

Pharmacological Experiments

HTRF Assay for Measuring cAMP in Cells


The method is based on a competitive immunoassay between native cAMP, which has been produced by the cells, and cAMP which is labelled with cAMPD2 conjugate. The tracer binding was visualized by a monoclonal antibody, anti-cAMP labelled with cryptate [HTRF=homogeneous time-resolved fluorescence].


The specific signal is inversely proportional to the cAMP concentration of the samples employed.


The 665 nm/620 nm fluorescence ratio was evaluated.


The following material was used: 96-well plates for the tissue culture, 96-well plates with black edge and black base (e.g. Fluotrac 600 from Greiner), 96-well plates for the substance dilutions of polypropylene and cAMP Femtomolar (4000 wells Kit, CIS Bio International # 62AM5PEJ).


The following reagents were used: BSA (bovine serum albumin) Fraction V protease-free, IBMX (3-isobutyl-1-methylxanthine), hFSH (human follicle stimulating hormone), Triton X-100 analytical grade, potassium fluoride analytical grade, G 418 (Geneticin) and Accutase.


Buffer 1 (washing and testing buffer) contained PBS, 1 mM CaCl2, 1 mM MgCl2, 0.2% glucose; 0.1% BSA, 1 mM IBMX.


Buffer 2 (2× lysis buffer) contained 1% Triton X-100 in PBS (without CaCl2 and MgCl2).


Buffer 3 (assay buffer) contained 50 mM potassium phosphate buffer (pH 7.0); 800 mM potassium fluoride; 0.2% BSA (always added fresh).


Procedure:

On day 1, the cells were seeded in 96-well plates (3×104 cells per well hFSHR clone 16 cells (CHO cells stably transfected with the human FSH receptor in 150 μl of medium). The next day, test substance dilutions were made up. For this purpose, all the substances were diluted in ice-cold buffer 1 (with or without hFSH), and the substance dilutions were placed on ice until applied to the cells.


The cell supernatant was then aspirated off, and the cells were washed 2× with 200 μl of buffer 1. The cells were treated with 60 μl of the appropriate substance concentrations at 37° C. for 2 h. The cells were then lysed with 60 μl of buffer 2 (put onto the supernatant) (on a plate shaker at RT for 30 min).


The test conjugates (cAMP-D2 and anti-cAMP cryptate, CIS Bio) were diluted in buffer 3 in accordance with the manufacturers' information. The actual mixture for measurement was pipetted into a black 96-well plate (in each case 15 μl of the cell lysate diluted with 35 μl of buffer 1; firstly 25 μl of cAMP-D2 conjugate were pipetted and, after 10 min, 25 μl of the anti-cAMP cryptate were added). This is followed by incubation at RT for 90 minutes. The measurement was carried out in a PheraStar (BMG).
