Multiple sensory and functional effects of non-phenolic aminodimethylene nonivamide: an approach to capsaicin antagonist.
1. Hexylaminodimethylene nonivamide (CAPCNC6, 0.1-10 microM) inhibited the contractility of isolated guinea pig right atria, toxically revealed positive inotropic, chronotropic and then a cardiac arrest effect at 100 microM and inhibited capsaicin (1.0 microM)-induced cardiotonic effects. 2. CAPCNC6 (0.1-10 microM)-induced aorta contractions were inhibited in the presence of flunarizine, atropine, phentolamine, Ca(2+)-free solution and pre-treatment of the animal with capsaicin. 3. CAPCNC6 (1.0-300 microM)-induced trachea contractions were inhibited in the presence of capsazepine, ruthenium red, hCGRP8-37 and pre-treatment of the animal with capsaicin.
