Stress and illness connection is complex and involves multiple physiological systems. Panax ginsengs, reputed for their broad-spectrum "cure-all" effect, are widely prescribed to treat stress and related illnesses. However, the identity of ginseng's "cure-all" medicinal compounds that relieve stress remains unresolved. Here, we identify ginsentides as the principal bioactives that coordinate multiple systems to restore homeostasis in response to stress. Ginsentides are disulfide-rich, cell-penetrating and proteolytic-stable microproteins. Using affinity-enrichment mass spectrometry target identification together with , and validations, we show that highly purified or synthetic ginsentides promote vasorelaxation by producing nitric oxide through endothelial cells intracellular PI3K/Akt signaling pathway, alleviate 1-adrenergic receptor overactivity by reversing phenylephrine-induced constriction of aorta, decrease monocyte adhesion to endothelial cells CD166/ESAM/CD40 and inhibit P2Y12 receptors to reduce platelet aggregation. Orally administered ginsentides were effective in animal models to reduce ADP-induced platelet aggregation, to prevent collagen and adrenaline-induced pulmonary thrombosis as well as anti-stress behavior of tail suspension and forced swimming tests in mice. Together, these results strongly suggest that ginsentides are the principal panacea compounds of ginsengs because of their ability to target multiple extra- and intra-cellular proteins to reverse stress-induced damages.
压力与疾病之间的联系错综复杂,涉及多个生理系统。人参因其具有广谱的“万灵药”功效而闻名,被广泛用于治疗压力及相关疾病。然而,人参中缓解压力的“万灵药”药用化合物的具体成分仍未明确。在此,我们确定人参皂苷是主要的生物活性物质,它们能协调多个系统,以应对压力并恢复体内平衡。人参皂苷是富含二硫键、可穿透细胞且对蛋白水解稳定的微蛋白。通过亲和富集质谱靶向鉴定以及[此处原文缺失三个并列的验证方式,无法准确翻译]验证,我们发现高度纯化或合成的人参皂苷可通过内皮细胞内的PI3K/Akt信号通路产生一氧化氮来促进血管舒张,通过逆转去氧肾上腺素诱导的主动脉收缩来减轻β1 - 肾上腺素能受体过度激活,减少单核细胞与内皮细胞的黏附(通过CD166/ESAM/CD40),并抑制P2Y12受体以减少血小板聚集。口服人参皂苷在动物模型中可有效降低ADP诱导的血小板聚集,预防胶原蛋白和肾上腺素诱导的肺血栓形成,以及在小鼠的尾悬和强迫游泳试验中表现出抗应激行为。总之,这些结果有力地表明,人参皂苷是人参的主要灵丹妙药成分,因为它们能够靶向多种细胞外和细胞内蛋白质,以逆转压力诱导的损伤。
