在常温常压下稳定,这种物质呈现灰黄色至白色结晶状。
4-戊炔酸可用作有机合成中间体,广泛应用于医药、材料科学和农业等领域。它能够作为制备抗菌药、抗炎药、导电材料及光电材料的中间体。在农业领域,该化合物还可用作植物生长调节剂的原料,通过调节植物的生长和发育过程,提高农作物的产量和品质。
合成将20%氢氧化钠溶液(200g)与含有戊烯酸的甲苯(100g)溶液一同加入500ml四颈烧瓶中,在室温下进行反应。逐滴加总量并搅拌20分钟后,待反应温度升至60°C时通过气相色谱法确认反应完全。随后冷却分离液体,并去除有机层。
在20~40°C的条件下,向水层中缓慢滴加10%硫酸(600g,0.612mol),并在搅拌下进行操作。使用混合溶剂(甲苯200g+四氢呋喃100g)提取两次,收集300g有机层并减压蒸馏,得到50g标题化合物(产率84%),为浅棕色晶体。

When innate immune cells such as macrophages are challenged with environmental stresses or infection by pathogens, they trigger the rapid assembly of multi-protein complexes called inflammasomes that are responsible for initiating pro-inflammatory responses and a form of cell death termed pyroptosis. We describe here the identification of an intracellular trigger of NLRP3-mediated inflammatory signaling, IL-1β production and pyroptosis in primed murine bone marrow-derived macrophages that is mediated by the disruption of glycolytic flux. This signal results from a drop of NADH levels and induction of mitochondrial ROS production and can be rescued by addition of products that restore NADH production. This signal is also important for host-cell response to the intracellular pathogen Salmonella typhimurium, which can disrupt metabolism by uptake of host-cell glucose. These results reveal an important inflammatory signaling network used by immune cells to sense metabolic dysfunction or infection by intracellular pathogens.
