A series of novel guanidine derivatives were synthesized in three steps and their anti-inflammatory activities in vitro and in vivo evaluated. 2-Aminopyridin-3-ol (1) was reacted with thiophosphoryl chloride (2) to give a monochloride (3). It was further reacted with cyanamide to afford the corresponding cyanamine (4), which was subsequently reacted with different heterocyclic amines to form the title
通过三个步骤合成了一系列新型胍衍生物,并在体内和体外评估了它们的抗炎活性。使2-氨基吡啶-3-醇(1)与硫代磷酰氯(2)反应,得到一氯化物(3)。使其进一步与氰酰胺反应,得到相应的氰胺(4),其随后与不同的杂环胺反应以形成标题化合物(5a-1)。胍官能团中的取代基影响抗炎活性的效力。具有苯并噻唑,氟苯基和哌嗪基部分的化合物增强了抗炎活性。
