Novel dihydropyrazole derivatives linked with multi(hetero)aromatic ring: Synthesis and antibacterial activity

Recent Research Progress in Oxime Insecticides and Perspectives for the Future

“…As significant components of nitrogen-containing heterocyclic systems, pyrazole compounds exhibit remarkable biological activity in the field of pesticides, including antibacterial, , herbicidal, insecticidal, , and plant growth regulation . Based on the skeleton of pyrazoloxime ether and the principle of biomimetic sorting, Zou et al synthesized pyrazole oxime derivatives with various substituted pyridine rings (Figure A) in 2014, which displayed potent insecticidal activity against Aphis laburni Kaltenbach ( A. laburni Kaltenbach ) and Tetranychus cinnbarinus ( T. cinnabarinus ) at 200 mg/L .…”

Design, Synthesis, and Antimicrobial Evaluation of Novel Pyrazoles and Pyrazolyl 1,3,4-Thiadiazine Derivatives

“…The rate of bacterial resistance to antibiotics is higher than the rate of development of new classes of antibiotics [2] so the design and synthesis of new compounds have potential antimicrobial activity are very important issue. Pyrazole derivatives have great attention due to their interesting biological and pharmaceutical activities such as antidepressant [3], antioxidant [4], anti-inflammatory [5], anticancer [6], antimicrobial [7,8,9], antiviral [10,11], anticonvulsant [12], and insecticidal activities [13]. In addition, the natural pyrazole C-glycoside, pyrazofurin (4-hydroxy-3β- d -dribofuranosyl-1 H -pyrazole-5-carboxamide) has a broad spectrum of antimicrobial, antiviral, and antitumor activities [14].…”
