Results The result indicates that substituents of para- and ortho-positions in phenyl ring of aryloxyalkylamine greatly influence the bioactivity. Conclusion The biophore model and 3D-QSAR equation help us not only further understand receptor-ligand interactions, but also design new compounds with better bioactivity.展开更多
