title: Spectral mapping, a technique for classifying biological activity profiles of chemical compounds.
abstract: A mathematical technique is described that separates potency from spectral information in biological activity spectra. The technique is a preliminary step in the classification of chemical compounds and in the structuring of pharmacological assays. The method is illustrated using previously reported results on 40 neuroleptics in 12 assays on rats. Principal component analysis and cluster analysis are shown to provide complementing information.
