Abstract

Objectives: Tilia viridis (Bayer) Simonk. (Malvaceae) is widely distributed in Argentina and employed for its tranquilizing properties. Other species of the genus (Tilia europaea L., Tilia cordata Mill., Tilia platyphyllos Scop.) have been traditionally used for the treatment of epilepsy. Epilepsy affects approximately 65 million people worldwide and is characterized by an imbalance between excitatory and inhibitory processes in the brain, leading to unpredictable, unprovoked, recurrent seizures. Current pharmacological interventions often present mild to moderately severe side effects. Epilepsy has been associated with oxidative and nitrative stress as well as neuroinflammation. Herbal medicine therapies may offer new treatment options with multi-target antioxidant and anticonvulsant effects for patients whose seizures remain uncontrolled, potentially providing cost-effective solutions for individuals worldwide suffering from uncontrolled epilepsy.The aim of this study was to demonstrate the anticonvulsant activity of a standardized T. viridis aqueous extract (TE).

Methods: Study of the constituents of TE, TE's antioxidant and anticonvulsant activities and toxicity, and analysis of the possible relation between the potential activities and the compounds present in the extract. In order to demonstrate TE's anticonvulsant activity a zebrafish model was used. The study also assessed TE's toxicity and antioxidant activity. To standardize the extract, total polyphenols and flavonoids were quantified and specific flavonoids were identified and quantified using HPLC-MS/MS and HPLC-UV.

Results: TE exhibited anticonvulsant activity at low concentrations and demonstrated antioxidant effects by scavenging free radicals, exhibiting superoxide dismutase and peroxidase-like activities, as well as inhibiting lipoperoxidation. These actions can be attributed to the presence of polyphenols, particularly flavonoids.

Conclusion: TE holds promise as a complementary herbal medicine in the treatment of epilepsy and may also offer benefits for other neuropathies associated with oxidative stress, such as Parkinson's disease and Alzheimer's disease.

椴树水提取物对斑马鱼 PTZ 诱导癫痫模型的体外抗氧化活性和抗惊厥特性
目的:Tilia viridis (Bayer) Simonk.(锦葵科)广泛分布于阿根廷,具有镇静作用。该属的其他物种(Tilia europaea L.、Tilia cordata Mill.、Tilia platyphyllos Scop.)历来被用于治疗癫痫。全世界约有 6500 万人患有癫痫,其特点是大脑兴奋和抑制过程失衡,导致不可预测、无诱因、反复发作的癫痫。目前的药物干预通常会产生轻度到中度严重的副作用。癫痫与氧化和硝化压力以及神经炎症有关。中草药疗法可为癫痫发作仍未得到控制的患者提供具有多靶点抗氧化和抗惊厥作用的新治疗方案,从而为全球未得到控制的癫痫患者提供具有成本效益的解决方案。本研究的目的是证明标准化 T. viridis 水提取物(TE)的抗惊厥活性:研究 TE 的成分、TE 的抗氧化和抗惊厥活性及毒性,并分析潜在活性与提取物中存在的化合物之间的可能关系。为了证明 TE 的抗惊厥活性,使用了斑马鱼模型。研究还评估了 TE 的毒性和抗氧化活性。为了使提取物标准化,使用 HPLC-MS/MS 和 HPLC-UV 对总多酚和黄酮类化合物进行了定量,并对特定的黄酮类化合物进行了鉴定和定量:TE 在低浓度时具有抗惊厥活性,并通过清除自由基、显示超氧化物歧化酶和过氧化物酶样活性以及抑制脂质过氧化反应而显示出抗氧化作用。这些作用可归因于多酚,特别是类黄酮的存在:TE 有望成为治疗癫痫的辅助草药,还可能对帕金森病和阿尔茨海默病等其他与氧化应激相关的神经病有好处。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
