Newly synthesized compound, 2-(1-,2-benzisoxazol-3-yl)-3-[2-(2-piperidinoethoxy)phenyl]acrylonitrile (SX-284) inhibited electrically evoked acetylcholine release from the stores in the myenteric plexus-longitudinal strips of guinea pig ileum which was labelled with [3H]-choline but not the evoked release of tracer from rat vas deferens after labelling with [3H]-norepinephrine. These results support our previous findings that SX-284 specifically inhibit acetylcholine release from the vagus nerve…

TLDR
SX-284 specifically inhibits the acetylcholine release from the vagus nerve, and spontaneous movement of the guinea pig ileum was dose-dependently depressed by SX-284.
