compounds were screened for their β -glucuronidase inhibition activity. Compounds 5a , 5e , 5h , and 5l exhibited an excellent β -glucuronidase inhibitory activity as compared to the standard inhibitor. Graphical Abstract A new series of hydrazinecarboxamides and their 1,2,4-triazole derivatives has been reported. The synthesized compounds were evaluated for their β -glucuronidase inhibition activity
摘要通过将相应的酰肼( 3a - f )与异氰酸甲氧基苯基酯( 4a - c )缩合,合成了 一系列带有各种甲氧基苯基和甲氧基苯乙基的肼甲酰胺 ( 5a - n )。通过在2 N氢氧化钠水溶液中回流,将肼甲酰胺( 5a - n )脱氢环化, 得到相应的甲氧基苯基和甲氧基苯乙基取代的三唑( 6a - l )。筛选所有合成的化合物的 β -葡糖醛酸糖苷酶抑制活性。与标准抑制剂相比,化合物 5a , 5e , 5h 和 5l 具有出色的 β- 葡萄糖醛酸苷酶抑制活性。 图形摘要 已经报道了一系列新的肼甲酰胺及其1,2,4-三唑衍生物。评价合成的化合物的 β- 葡萄糖醛酸苷酶抑制活性。
