摘要: Three-dimensional pharmacophore hypotheses were built from a set of 10 octopamine (OA) agonist 2-(Arylimino)imidazolidines (AIIs), 2-(Arylimino)thiazolidines (AITs) and 2-(Arylimino)oxazolidines (AIOs). Among the common-featured models generated by program Catalyst/HipHop, hypothesis including ring aromatic (RA), positive ionizable (PI) three hydrophobic aliphatic (HpAl) features was considered to be important in evaluating OA-agonist activity. Active OA 2,6-Et2 AII mapped well onto all RA, PI HpAl hypothesis. On other hand, less active compounds shown difficult achieve energetically favorable conformation which is found molecules order fit 3-D common-feature models. Taken together, 2,6-Et2-Ph foramidine structures are as agonists. The present studies on agonists demonstrate that sites located molecule seem essential for
