[Image] [Image] ACTIVITY : Analgesic; Antiinflammatory; Uropathic; Gynecological; Gastrointestinal-Gen.; Respiratory-Gen.; Antipsoriatic; Antipruritic; Dermatological; Virucide; Antidepressant; Antidiabetic; Antiulcer. MECHANISM OF ACTION : Transient receptor potential vanilloid 1 (TRPV1) receptor antagonist. The ability of (I) to inhibit the current induced by capsaicin was tested in primary culture of dorsal rout ganglion (DRG) cells of rat. The results showed that N-[6-(pyrrolidin-1-yl)-pyridin-3-yl]-5-fluoro-1-(3-fluorobenzyl)-1H-indole-2-carboxamide exhibited 46% inhibition in the DRG patch thus good antagonistic activity against TRPV1 receptor. |
