일반 설명
Citraconic anhydride is a derivative of maleic anhydride and is also known as 2-methylmaleic anhydride. It is highly reactive due to the presence of anhydride groups and can undergo hydrolysis, esterification, amidation, and addition reactions. It can be used as a crosslinking agent to create covalent bonds between polymer chains, enhancing the mechanical strength and thermal stability of the polymer network. They arepotential tools for bioconjugation and immobilization of bioactive molecules.
애플리케이션
Citraconic anhydride can be used:
- As an electrolyte additive for high-temperature pouch lithium-ion batteries. Citraconic anhydride reduces the interfacial impedance of pouch cells during high-temperature storage and enhances their stability.
- As a pH-sensitive linker to surface functionalization of biomolecules used in drug delivery systems. The high pH sensitivity of citraconic anhydride conjugates is attributed to the presence of a double bond that restricts the separation between the amide and carboxylic acid groups.
- As a reagent to synthesize new thiopyrano[2,3-d][1,3]thiazole derivatives via hetero-Diels–Alder reactions. These thiopyrano derivatives exhibit diverse biological activities such as anticancer, antiviral, and antitrypanosomal.
- As a co-monomer in the ring-opening polymerization with d-xylose 3,5-anhydrosugar derivative to form novel sugar-derived polyesters, with up to 100% renewable content. This can serve as a sustainable feedstock for polymer synthesis.

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
