描述 | Pitofenone HCl, a spasmolytic compound, inhibits the acetylcholinesterase (AChE) activity from bovine erythrocytes and from electric eel with Kis of 36 and 45 μM, respectively[1]. Pitofenone (10-3 mol/l) antagonized completely spontaneous phasic-rhythmic as well as norepinephrine- or acetylcholine-induced phasic activity. Pitofenone (10-6 to 10-3 mol/l) antagonized the high potassium-induced activation in a concentration-dependent way. The EC50 of pitofenone amounted to 2 X 10-4 mol/l. Pitofenone has a direct relaxant effect on smooth muscle of the upper urinary tract, whereas fenpiverinium has exclusively anticholinergic properties[2]. |
