Site contribution to the energy-optimized pharmacophores obtained from PDB complexes in bold from Table 1.

Required and optional sites at the structure-based common pharmacophore are shown in bold and italics, respectively. The other sites are not part of the structure-based common pharmacophore. Data at the same raw for different PDB complexes indicate that the pharmacophore site is shared by these complexes.基于结构的共同药效团（structure-based common pharmacophore）中的必需位点与可选位点分别以粗体与斜体标注。其余位点均不属于该基于结构的共同药效团。不同PDB（Protein Data Bank）复合物的同一行数据表明，这些复合物共享该药效团位点。
