Kinsenoside is the major bioactive component from herbal medicine with a broad range of pharmacological functions. Goodyeroside A, an epimer of kinsenoside, remains less explored. In this report we chemically synthesized kinsenoside, goodyeroside A and their analogues with glycan variation, chirality inversion at chiral center(s), and bioisosteric replacement of lactone with lactam. Among these compounds, goodyeroside A and its mannosyl counterpart demonstrated superior anti-inflammatory efficacy. Furthermore, goodyeroside A was found to suppresses inflammatory through inhibiting NF-κB signal pathway, effectively. Structure-activity relationship is also explored for further development of more promising kinsenoside analogues as drug candidates.

人参皂苷是来自草药的主要生物活性成分，具有广泛的药理功能。Goodyeroside A 是kinsenoside 的一种差向异构体，仍然很少被探索。在本报告中，我们化学合成了人参皂苷、Goodyeroside A 及其类似物，具有聚糖变异、手性中心的手性反转以及内酰胺对内酯的生物等排置换。在这些化合物中，goodyeroside A 及其甘露糖基对应物表现出优异的抗炎功效。此外，还发现枸杞苷 A 通过抑制 NF-κB 信号通路有效抑制炎症。还探索了构效关系，以进一步开发更有前途的人参皂苷类似物作为候选药物。
