Abstract
The relationship between the lipophilic character of chlorpromazine and seven of its metabolites and their ability to inhibit horse serum cholinesterase (Ki) has been investigated. Log(1/Ki) values were correlated with log P octanol partition coefficients (r = 0.88, P less than 0.01, n = 8). The inhibitor values ranged from 2.7 x 10(-6) M for chlorpromazine to 48.6 x 10(-6) M for monodesmethylchlorpromazine sulphoxide. Ionization constants were determined by limiting solubility, spectrophotometry and pH-partition characteristics. Demethylated metabolites were more basic than the tertiary amines and the sulphoxides were slightly less basic than the corresponding sulphides.
