The hallucinogenic (psychotomimetic) potency of 10 mescaline analogs was examined by molecular connectivity analysis. Potencies could be described by a two-term relating equation, which explained 94% of the variance in activity, on the basis of structural variation, 2,5-Dimethoxy substitution as well as the nature of the 4-position substituent played an important role in determining...
A series of ring-substituted hallucinogenic amphetamines has been analyzed using molecular connectivity. A correlating equation has been found between potency and connectivity terms. The equation permits an interpretation of SAR. The equation is capable of predicting potency for amphetamines not in the list and mescalines and tryptamines.
