Aging is associated with the increased risk of most age-related diseases in humans. Complanatoside A (CA) is a flavonoid compound isolated from the herbal medicine Semen Astragali Complanati. CA was reported to have potential anti-inflammatory and anti-oxidative activities. In this study, we investigated whether CA could increase the stress resistance capability and life span of . Our results showed that CA could extend the longevity of in a dosage-dependent manner, while 50 μM of CA has the best effect and increased the life span of by about 16.87%. CA also improved the physiological functions in aging worms, such as enhanced locomotor capacity, and reduced the accumulation of the aging pigment. CA could also reduce the accumulation of toxic proteins (α-synuclein and β-amyloid) and delay the onset of neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease, in models of . Further investigation has revealed that CA requires DAF-16/FOXO, SKN-1, and HSF-1 to extend the life span of . CA could increase the antioxidation and detoxification activities regulated by transcription factor SKN-1 and the heat resistance by activating HSF-1 that mediated the expression of the chaperone heat shock proteins. Our results suggest that CA is a potential antiaging agent worth further research for its pharmacological mechanism and development for pharmaceutical applications.
衰老与人类大多数与年龄相关疾病的风险增加有关。合萌苷A(CA)是从中药材合萌种子中分离出的一种黄酮类化合物。据报道,CA具有潜在的抗炎和抗氧化活性。在本研究中,我们调查了CA是否能提高[具体生物名称未给出]的抗应激能力和寿命。我们的结果表明,CA能以剂量依赖的方式延长[具体生物名称未给出]的寿命,其中50μM的CA效果最佳,使[具体生物名称未给出]的寿命延长了约16.87%。CA还改善了衰老线虫的生理功能,如增强运动能力,并减少了衰老色素的积累。在[具体疾病模型未给出]模型中,CA还能减少有毒蛋白质(α-突触核蛋白和β-淀粉样蛋白)的积累,并延缓神经退行性疾病如阿尔茨海默病和帕金森病的发病。进一步研究表明,CA需要DAF-16/FOXO、SKN-1和HSF-1来延长[具体生物名称未给出]的寿命。CA可通过激活介导伴侣热休克蛋白表达的HSF-1来增加转录因子SKN-1调节的抗氧化和解毒活性以及耐热性。我们的结果表明,CA作为一种潜在的抗衰老剂,其药理机制值得进一步研究,并有开发成药物应用的潜力。
