Butaclamol (AY-23,028) is a type of antipsychotic which was never marketed. [1] Sold as the hydrochloride salt for use in research, the compound acts as a dopamine receptor antagonist. [2]

Chemistry

pKa = 7.15 (uncorrected for ionic strength) [6]

McN-4171 is an analog of butaclamol. [6] [7] McN-4612-Y is also described in the attached article. This is similar to McN 4612-z except it is the opposite optical antipode. It is therefore supposedly an antipsychotic.
