which has been used to treat rheumatism and relieve pain in traditional Chinese medicine. We have developed a concise and general synthetic approach for INCA, which enabled gram-scale asymmetric syntheses of (−)-INCA, (−)-incarvilline, (−)-isoincarvilline, and six other INCA analogues. The synthesis of isoincarvilline was reported for the first time. Three structurally simplified analogues of INCA
(-)-Incarvillateine(INCA)是中华小Incarvillea sinensis的主要抗伤害感受成分,已用于治疗风湿病和缓解中药疼痛。我们已经为INCA开发了一种简明而通用的合成方法,该方法可以实现(-)-INCA,(-)-carcarlineline,(-)-isoincarvilline和其他六个INCA类似物的克级不对称合成。首次报道了异马胆碱的合成。还合成了INCA的三种结构简化的类似物。体内筛选发现INCA和两种结构优化的类似物可有效防止乙酸诱导的扭体反应。此外,在福尔马林诱导的疼痛模型中证明了它们的镇痛效果。更重要的是,在备用神经损伤(SNI)模型中,给予20或40 mg / kg INCA和两种结构优化的类似物显示出强大的镇痛作用,
