Application
巴比妥酸与芳香醛在微波辐射下，无有机溶剂存在下，在碱性氧化铝上发生 Knoevenagel 缩合反应的效率提高。它也可用于碘的电化学氧化，使用循环伏安法和控制电位库仑法。
General description
巴比妥酸也被称为丙二酸脲或 6-羟基尿嘧啶，它是一种无臭粉末，可溶于水。它具有很高的药理活性，可用来合成加成衍生物，用于新药开发。它基本上作用于中枢神经系统 (CNS) 抑制剂，因此具有从轻度镇静到完全麻醉的广泛范围。

GABA type A receptors (GABAAR), the brain's major inhibitory neurotransmitter receptors, are the targets for many general anesthetics, including volatile anesthetics, etomidate, propofol, and barbiturates. How such structurally diverse agents can act similarly as positive allosteric modulators of GABAARs remains
