General description
柠檬酸酐是马来酸酐的衍生物，也称为2-甲基马来酸酐。由于酸酐基团的存在，它具有高活性，可以进行水解、酯化、酰胺化和加成反应。 它可以作为交联剂，在聚合物链之间形成共价键，提高聚合物网络的机械强度和热稳定性。它们是生物偶联和生物活性分子固定的潜在工具。
Application
柠檬酸酐可作为：
- 高温袋式锂离子电池的电解质添加剂。柠檬酸酐降低了袋状电池在高温贮存过程中的界面阻抗，提高了袋状电池的稳定性。
- 作为一种pH敏感连接剂，用于药物输送系统生物分子的表面功能化。柠檬酸酸酐偶联物的高pH敏感性是由于其双键的存在限制了酰胺和羧基之间的分离。
- 作为试剂，通过杂-Diels–Alder反应合成新的硫代吡喃[2,3-d][1,3]噻唑衍生物。这些硫代吡喃衍生物具有多种生物活性，如抗癌、抗病毒和抗锥虫。
- 作为共聚单体与d-木糖3,5-无水糖衍生物开环聚合，形成新型糖源聚酯，可再生含量高达100%。 可以作为聚合物合成的可持续原料。

A stroke affecting the somatosensory pathway can trigger central post-stroke pain syndrome (CPSP). The symptoms often include hyperalgesia, which has also been described in rodents after the direct damage of the thalamus. Previous studies have shown that hemorrhagic stroke or

The development of insoluble, intracellular neurofibrillary tangles composed of the microtubule-associated protein tau is a defining feature of tauopathies, including Alzheimer's disease (AD). Accumulating evidence suggests that tau pathology co-localizes with RNA binding proteins (RBPs) that are known markers for
