Abstract

Succinum is an organic mineral formed from the resin of ancient coniferous and leguminous plants, which is applied for tranquilizing mood, promoting blood circulation, and removing blood stasis in Chinese medicine. For quite a long time, the modern research of succinum mainly focuses on the study of physical and chemical properties and authenticity identification while few reports on its medicinal mechanism. In current study, we evaluated different solvent extracts of succinum on carotid artery ligation rats mimicking vascular dementia. It was found that ethyl acetate extracts of succinum significantly improved the learning and memory abilities of model rats and inhibited neuronal apoptosis in the hippocampus. On a mice hippocampal neuronal cell line (HT22), ethyl acetate extracts of succinum also exerted better action trend in inhibiting cell apoptosis induced by oxygen glucose deprivation (OGD). By using XAV-939 on both and studies, it was found that ethyl acetate extracts of succinum might exert these functions by regulating the GSK3β/β-catenin pathway. These studies revealed the neuronal function of succinum, which explained the traditional effects of succinum and provided more modern scientific basis for its clinical application.

摘要

琥珀是由古代针叶树和豆科植物的树脂形成的有机矿物,在中医中用于安神、促进血液循环和活血化瘀。长期以来,现代对琥珀的研究主要集中在理化性质和真伪鉴定方面,而关于其药用机制的报道较少。在本研究中,我们评估了琥珀不同溶剂提取物对模拟血管性痴呆的颈动脉结扎大鼠的作用。发现琥珀乙酸乙酯提取物显著改善了模型大鼠的学习和记忆能力,并抑制了海马神经元凋亡。在小鼠海马神经元细胞系(HT22)上,琥珀乙酸乙酯提取物在抑制氧糖剥夺(OGD)诱导的细胞凋亡方面也表现出较好的作用趋势。通过在体内和体外研究中使用XAV-939,发现琥珀乙酸乙酯提取物可能通过调节GSK3β/β-连环蛋白通路发挥这些作用。这些研究揭示了琥珀的神经元功能,解释了琥珀的传统功效,并为其临床应用提供了更多现代科学依据。
