An independent claim is included for preparation of (I). [Image] ACTIVITY : Antiinfertility; Osteopathic. No biological data is given. MECHANISM OF ACTION : Follicle-stimulating hormone (FSH) receptor antagonist. The follicle-stimulating hormone (FSH) antagonist activity of N-[(R)-2-[1-(4-cyanobutyl)-1H-indol-3-yl]-1-(hydroxymethyl)ethyl]-3'-fluoro-4'-methoxy[1,1'-biphenyl]-3-carboxamide (Ia) was tested as follows: CHO cells stably transfected with human follicle stimulating hormone (hFSH) receptor in 150 mu l of medium were seeded in 96-well plates (3x104 cells per well hFSHR clone 16 cells). (Ia) was diluted in ice-cold buffer 1 containing PBS, calcium chloride (1 mM), magnesium chloride (1 mM), glucose (0.2%), BSA (bovine serum albumin) (0.1%) and IBMX (3-isobutyl-1-methylxanthine) (1 mM) (with or without hFSH), and the substance dilutions were placed on ice until applied to the cells. The cell supernatant was aspirated off, and the cells were washed with buffer 1 (200 mu l). The cells were treated with the test substance (60 mu l) at 37[deg]C for 2h. The cells were lysed with buffer 2 containing triton X-100 (1%) in PBS (without calcium chloride and magnesium chloride). The test conjugates (XL-665 and anti-cAMP cryptate) were diluted in buffer 3 containing potassium phosphate buffer (50 nM, pH 7), potassium fluoride (800 mM), BSA (0.2%). The actual mixture for measurement was pipetted into a black 96-well plate (in each case 15 mu l of the cell lysate diluted with 35 mu l of buffer 1; firstly 25 mu l of XL-665 conjugate were pipetted and, after 10 min, 25 mu l of the anti-cAMP cryptate were added). This was followed by incubation at room temperature for 90 minutes. (Ia) Showed an IC 50value of 100 nM.
