We report the discovery of spiro[cyclohexane-pyrano[3,4-b]indole]-amines, as functional nociceptin/orphanin FQ peptide (NOP) and opioid receptor agonists with strong efficacy in preclinical models of acute and neuropathic pain. Utilizing 4-(dimethylamino)-4-phenylcyclo-hexanone 1 and tryptophol in an oxa-Pictet-Spengler reaction led to the formation of spiroether 2, representing a novel NOP and opioid peptide receptor agonistic chemotype. This finding initially stems from the systematic derivatization of 1, which resulted in alcohols 3-5, ethers 6 and 7, amines 8-10, 22-24, and 26-28, amides 11 and 25, and urea 12, many with low nanomolar binding affinities at the NOP and mu opioid peptide (MOP) receptors.
我们报告了螺[环己烷-吡喃并[3,4-b]吲哚]-胺的发现，其作为功能性孤啡肽/孤啡肽FQ肽（NOP）和阿片受体激动剂，在急性和神经性疼痛的临床前模型中具有强大疗效。利用4-(二甲基氨基)-4-苯基环己酮1和色醇进行氧杂-Pictet-Spengler反应，生成了螺醚2，它代表了一种新型的NOP和阿片肽受体激动剂化学类型。这一发现最初源于对1的系统衍生化，衍生化产物包括醇3-5、醚6和7、胺8-10、22-24以及26-28、酰胺11和25，还有脲12，其中许多在NOP和μ阿片肽（MOP）受体上具有低纳摩尔的结合亲和力。
