[Image] - ACTIVITY : Analgesic; Antimigraine; Antidepressant; Nootropic; Neuroprotective; Antiparkinsonian; Anticonvulsant; Antiasthmatic; Antitussive; Uropathic; Antiulcer; Antiinflammatory; Cerebroprotective; Ophthalmological; Dermatological; Antiallergic; Antipsoriatic; Antidiarrhea; Antipruritic; Osteopathic; Antiarthritic; Antirheumatic; Antialcoholic; Cardiant; Vulnerary; Tranquilizer. - MECHANISM OF ACTION : (A) are ligands of the vanilloid receptors of subtype 1 (VR1/TRPV1 receptors). The compound 2-(3-fluoro-4-(methylsulfonylamino)phenyl)-N -((2-(piperidin-1-yl)-6-trifluoromethyl-pyridin-3-yl)methylpropionam ide had IC50 for displacement of capsaicin from the human receptor (expressed in CHO K1 cells) of 218 nM.
