Abstrakt: Quantitative structure-toxicity relationships were developed for the prediction of aqueous toxicities for Poecilia reticulata(guppy) using the CODESSA treatment. A two-parameter correlation was found for class 1 toxins with R2 0.96, and a five-parameter correlation was found for class 2 toxins with R2 0.92. A five-parameter correlation for class 3 toxins had R2 0.85. The correlations for class 4 toxins were less satisfactory. All the descriptors utilized are calculated solely from the structures of the molecules, which makes it possible to predict unavailable or unknown toxins.
