From the calculations, it can be found that the van der Waals interactions, the hydrophobic interactions, as well as the H-bonding interactions are crucial for the ligand binding. The 4-phenylamino group can produce strong van der Waals adn hydrophobic interactions with the nonpolar side chains of the residues deep in the binding cleft. The R^1 and R^2 substituents on the bicyclic chromophore can also produce strong van der Waals and hydrophobic interactions with the residues located at the exterior part of the binding pocket. Moreover, the two N atoms of the quinazoline can form H-bonds with EGFR, which will produce significant contribution to biological activities. The calculated nonbonded interactions between anilinoquinazolines and EGFR, as well as the information obtained from the predicted complexes, can interpret the structure-activities of the inhibitors well, which can afford us important information for structure-based drug design.

从模拟结果得到的抑制剂和靶酶之间的相互作用模式表明范德华相互作用、疏水相互作用以及氢键相互作用对抑制剂的活性都有重要的影响，抑制剂的苯胺部分位于活性口袋的底部，能够与受体残基的非极性侧链产生很强的范德华和疏水相互作用，抑制剂双环上的取代基团也能和活性口袋外部的部分残基形成一定的范德华和疏水性相互作用，而抑制剂喹唑啉环上的氮原子能和周围的残基形成较强的氢键相互作用，对抑制剂的活性有较大的影响，计算得到抑制剂和靶酶之间的非键相互作用能以及抑制剂和靶酶之间的相互作用信息能够很好地解释抑制剂活性和结构的关系，为全新抑制剂的设计提供了重要的结构信息。
