  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.

  光氧化还原催化剂启用的叔丁基芳基氨基甲酸酯的对选择性三氟甲基化

  摘要：

  已经广泛研究了使用自由基途径在芳环上直接结合三氟甲基。然而，一类芳烃的直接高对位选择性 CH 三氟甲基化尚未实现。在这项研究中，我们报告了使用 Langlois 试剂对芳基氨基甲酸酯进行光促进的 4,5-二氯荧光素 (DCFS)对位选择性 C-H 三氟甲基化。初步机理研究表明，活化的有机光催化剂与芳基氨基甲酸酯配位导致对位选择性 C-H 三氟甲基化。十克规模的反应表现良好，突出了这一新协议的综合重要性。
