Structure-activity relationships for nitrogen-containing aromatics
Twenty-four nitrogen-containing aromatic molecules, mono- and dicyclic homologs from each of 12 different analog sets, were studied to determine their relative acute static toxicities, monitored as population growth impairment to the ciliate Tetrahymena pyriformis. Quantitative structure-activity correlations between the molecular descriptors log l-octanol/water partition coefficient (log Kow) and log toxicity are reported. Using the complete data set the descriptor does not provide an adequate model for predictability. A scatter plot of log Kow versus log toxicity suggests two parallel linear correlations: one consisting of the more complex multiple H-polar nitrogen-containing compounds and the other with the single H-polar and in-ring substituted nitrogen-containing compounds.
