  新型苯并恶唑酮衍生物作为18 kDa转运蛋白（TSPO）配体的设计，合成和结构-活性关系

  摘要：

  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。

  Benzoxazolone Carboxamides as Potent Acid Ceramidase Inhibitors: Synthesis and Structure–Activity Relationship (SAR) Studies

  摘要：

  Ceramides are lipid-derived intracellular messengers involved in the control of senescence, inflammation, and apoptosis. The cysteine amidase, acid ceramidase (AC), hydrolyzes these substances into sphingosine and fatty acid and, by doing so, regulates their signaling activity. AC inhibitors may be useful in the treatment of pathological conditions, such as cancer, in which ceramide levels are abnormally reduced. Here, we present a systematic SAR investigation of the benzoxazolone carboxamides, a recently described class of AC inhibitors that display high potency and systemic activity in mice. We examined a diverse series of substitutions on both benzoxazolone ring and carboxamide side chain. Several modifications enhanced potency and stability, and one key compound with a balanced activity stability profile (14) was found to inhibit AC activity in mouse lungs and cerebral cortex after systemic administration. The results expand our arsenal of AC inhibitors, thereby facilitating the use of these compounds as pharmacological tools and their potential development as drug leads.
