Novel benzo[d]oxazol-2(3H)-one derivatives were designed and synthesized, and their affinities against σ receptors were evaluated. On the basis of 31 compounds, a three-dimensional pharmacophore model for the σ1 receptor binding site was developed using the Catalyst 4.9 software package. The best 3D pharmacophore hypothesis, consisting of one positive ionizable, one hydrogen bond acceptor, two hydrophobic
设计并合成了新型的苯并[ d ]恶唑-2(3 H)-one衍生物,并评价了其对σ受体的亲和力。上的31种化合物,对于σ的三维药效团模型的基础1受体结合位点是使用Catalyst 4.9软件包开发的。最好的3D药效团假说由一个正离子化,一个氢键受体,两个疏水性芳香族和一个疏水性特征组成,提供了一个相关系数为0.89的3D-QSAR模型。最好的假设还通过三种独立的方法进行了验证,即Catacrst的CatScramble功能中包括的Fisher随机检验,留一法检验以及其他检验集的活性预测。所取得的结果将允许研究人员使用此3D药效团模型用于第二代高亲和力的σ的设计和合成1点的配体,以及发现其他铅化合物对此类受体的。
