In this study novel ligands of the translocator protein (TSPO), characterized by a five-membered aromatic heterocycle (i.e. oxazole, isoxazole, oxadiazole), a phenyl ring, and an amide side chain of carboxy or acetic type, were designed using a previously reported pharmacophore/topological model. Most of compounds showed significant TSPO binding affinity (Ki values in the nanomolar/submicromolar range)
在这项研究中,使用先前设计的新型转运蛋白(TSPO)的配体,其特征在于五元芳族杂环(即恶唑,异恶唑,恶二唑),苯环和羧基或乙酸型酰胺侧链。报告的药效团/拓扑模型。大多数化合物显示显著TSPO结合亲和力(K我在纳摩尔/亚微摩尔范围内的值),最高被显示通过oxazolacetamides 6。测试了许多化合物抑制人胶质母细胞瘤细胞系U87MG增殖/活力的能力。剂量-时间依赖性细胞对6d治疗的反应证明了所观察到的效应的特异性。6d的能力诱导线粒体膜耗散(Δm)证实了配体结合TSPO激活的细胞内促凋亡机制。
