Resumen:
Experimentally assigned values to binding affinity constants of flavonoid ligands towards the benzodiazepine site of the GABA(A) receptorcomplex were compiled from several publications, and enabled to perform a predictive analysis based on Quantitative StructureeActivity Relationships (QSAR). The best linear model established on 78 molecular structures incorporated four molecular descriptors, selected from morethan a thousand of geometrical, topological, quantum-mechanical and electronic types of descriptors and calculated by Dragon software. Anapplication of this QSAR equation was performed by estimating the binding affinities for some newly synthesized flavonoids displaying2-,7-substitutions in the benzopyrane backbone which still do not have experimentally measured potencies.eActivity Relationships (QSAR).
