  본 발명은 1,3,4-옥사디아졸을 합성하는 방법으로서, a) 무용매 조건에서, 기계적 분쇄법으로 히드라지드 화합물과 알데하이드 화합물을 반응시켜 N-아실히드라존 화합물을 합성하는 단계; 및 b) 무용매 조건에서, N-아실히드라존 화합물에 아이오딘계 산화제를 첨가한 후 산화 고리화 반응으로 1,3,4-옥사디아졸을 합성하는 단계를 포함한다. 본 발명에 따른 무용매 반응에 의한 1,3,4-옥사디아졸 합성법은 매우 높은 선택성과 용이한 방법으로 1,3,4-옥사디아졸을 높은 수율로 합성할 수 있으며 핸들링이 쉽다는 장점이 있다. 또한, 용매 내부의 소량의 물에 의해 다른 부산물이 생성되는 것을 방지 할 수 있으며 이는 합성되는 중간물질이 물에 의해 출발물질로 돌아가는 일도 방지 할 수 있다.

  本发明提供了一种合成1,3,4-噻二唑的方法，包括：a) 在无溶剂条件下，通过机械研磨法使酰肼化合物与醛化合物反应，合成N-酰肼化合物；及b) 在无溶剂条件下，向N-酰肼化合物中加入碘酸系氧化剂后，通过氧化闭环反应合成1,3,4-噻二唑。根据本发明，通过无溶剂反应合成的1,3,4-噻二唑具有非常高的选择性，并且能够以简单的方法和高的产率合成1,3,4-噻二唑，操作也简便。此外，可以防止由于溶剂内部少量水分而产生其他副产品，这也可以防止合成中间体由于水分而逆反应。

  A new series of 1,3,4‐oxadiazoles, 1,2,4‐triazoles, 1,3,4‐thiadiazoles were synthesized using alkylhydrazides as the starting materials, and then 1,2,4‐triazoles were used to synthesize [1,2,4]triazolo[3,4‐b][1,3,4]thiadiazoles. All the compounds were evaluated for in vitro antibacterial activity and antitumor activity.

  A novel series of 2-phenyl-5-(1,3-diphenyl-1H-pyrazol-4-yl)-1,3,4-oxadiazoles were designed and synthesized for selective COX-2 inhibition with potent anti-inflammatory activity. Among the compounds tested, 9g (2-(3-(4-nitrophenyl)-1-phenyl-1H-pyrazol-4-yl)-5-phenyl-1,3,4-oxadiazole) was found to be the most potent inhibitor of COX-2 with IC50 of 0.31 μM showing promising degree of anti-inflammatory activity in the carrageenan-induced rat paw edema model with ED50 of 74.3 mg/kg. The lead compound 9g further showed suppression of acetic acid-induced writhes comparable to that of aspirin and gastro-sparing profile superior to the aspirin. Molecular docking analysis displayed higher binding affinity of ligands towards COX-2 than COX-1.
