Treatment of frog neuromuscular preparations with chlorpromazine (5 mumol/l) resulted in a marked rise in miniature endplate potential (MEPP) frequency of greater than 100% within 30 min, and an increase in evoked transmitter release (quantal content 5-15) of about 35%.

The 3-dimensional molecular structures of methotrimeprazine, methotrimeprazine sulfoxide, and chlorpromazine sulfoxide were examined by X-ray crystallography. Previous studies of their dopamine receptor binding affinities have indicated that both chlorpromazine sulfoxide and methotrimeprazine sulfoxide lack neuroleptic potency. The crystal structures of
