Abstract: 3D pharmacophore model was characterized using a training set of gpIIb/IIIa inhibitors which consisted of 20 3,4-dihydro-1(1H)-isoquinolinone-based antagonists by the Catalyst program. The best models (linear r=0.7715) were used as database search queries to identify active compounds for glycoprotein IIb/IIIa receptor from the Chinese herbal drugs database (CHDD) and eight active compounds were found by further activity-determined experiment. The validity of the pharmocophore model was proved further by the experimental results.

Key words: 3D pharmacophore model, gpIIb/IIIa, Chinese herbal drugs database
