B115 (IUPAC name 1-methyl-4-[(E)-2-naphthalen-1-ylethenyl]-3,6-dihydro-2H-pyridine ^[1] ) is an inhibitor of the enzyme choline acetyltransferase (ChAT).

In vivo activity

B115 inhibits human ChAT with an IC₅₀ of 4.3 µM. ^[2] During in vivo testing, B115 has been found to partially protect against soman, a nerve agent, but it has been suggested that this may not be due to ChAT inhibition. ^{[3] [4]}
