Synthesis of 3-pyridyl-substituted 5-amino-1,2,4-triazoles from aminoguanidine and pyridinecarboxylic acids
摘要:
Effect of the molar ratio between reagents, temperature, and synthesis duration on the yield of 3-pyridylsubstituted 5-amino-1,2,4-triazoles in the reaction of aminoguanidine hydrochloride with pyridinecarboxylic acids under acid catalysis conditions was studied. A single-reactor method for synthesis of 3-pyridyl-substituted 5-amino-1,2,4-triazoles and their hydrochlorides was developed.

We herein report the conventional and microscale parallel synthesis of selective inhibitors of human blood coagulation factorXIIa and thrombin exhibiting a 1,2,4-triazol-5-amine scaffold. Structural variations of this scaffold allowed identifying derivative 21i, a potent 29 nM inhibitor of FXIIa, with improved selectivity over other tested serine proteases and also finding compound 21m with 27 nM

This process, when applied to histamine, leads to the competitive histamine H2-receptor antagonist prototype 3-amino-5-(2-amino-4-pyridyl)-1,2,4-triazole (7). The biaryl nature of 7 fixes internitrogen distances, and comparison of these with histamine suggests that 7 shares structural features more in common with histamine trans rather than histamine gauche conformations. Alkylation of the prototype
The best antibacterial effects were observed with 3(5)-phenyl-1H-1,2,4-triazol-5(3)-amine according to its MIC values (4–8 μg mL−1). All compounds were successful in blocking the growth of fungi. Acceptable antioxidant properties were observed only with 3(5)-(4-nitrophenyl)-1H-1,2,4-triazol-5(3)-amine.

摘要提出了一种通过硫脲,硫酸二甲酯和各种酰肼的一锅反应合成3(5)-取代的1,2,4-三唑-5(3)-胺的有效方法。1,2,4-三唑衍生物是在温和的条件下在水性介质中制备的,同时遵守一些绿色化学原理。无需任何进一步纯化即可轻松分离出产物,产率为83–95%。评估了所有合成化合物对各种革兰氏阳性和革兰氏阴性病原菌以及一些真菌病原体的抑制活性。根据其MIC值(4–8μgmL -1,使用3(5)-苯基-1 H -1,2,4-三唑-5(3)-胺观察到了最佳的抗菌作用)。所有化合物均能成功阻止真菌生长。仅使用3(5)-(4-硝基苯基)-1 H -1,2,4-三唑-5(3)-胺观察到可接受的抗氧化剂性能。 图形摘要通过硫脲,硫酸二甲酯和各种酰肼在水中作为溶剂的一锅反应,可有效地制备3(5)-取代的1,2,4-三唑-5(3)-胺。根据它们的MIC,MBC和MFC值证明了所有合成衍生物的抑制活性。发现它们是潜在的抗真菌剂。
