Abstract:

In this paper, PARM algorithm which can be used in QSAR research was put forward. In this algorithm, a set of pseudo atom was defined and a series of pseudo receptor model was generated by using genetic algorithm. These models which have high correlation between receptor-liagnd interaction and bioactivity can predict bioactivity of unknown molecules. This algorithm was used to investigate the K+ channel opener system. The reasonable results were obtained.

Key words: Pseudoreceptor model, Genetic algorithm, Quantitative structure-activity-relationship
