Selective 18 kDa translocator protein (TSPO) ligands are expected to be therapeutic agents with a wide spectrum of action on psychiatric disorders and fewer side effects. We designed novel benzoxazolone derivatives and examined the structure–activity relationship (SAR) of a series of compounds with various substituents at the amide part and C-5 position. Although a number of the synthesized compounds
选择性的18 kDa转运蛋白(TSPO)配体有望成为对精神疾病具有广泛作用且副作用较少的治疗剂。我们设计了新颖的苯并恶唑酮衍生物,并研究了在酰胺部分和C-5位置具有多个取代基的一系列化合物的结构-活性关系(SAR)。尽管许多合成的化合物显示出高的TSPO结合亲和力,但这些化合物的药物样性质较差。这些化合物的药代动力学特性的进一步优化导致发现化合物74,该化合物在大鼠Vogel冲突模型中表现出抗焦虑作用。
