title: The use of mass spectrometric data to predict biological activity.
abstract: The mass spectra of 75 analogs of trimethoprim were used in a study correlating mass spectrometric data with biological activity. Using pattern recognition techniques a correlation was obtained. Experiments to elaborate the basis of the correlation are described.
