“…The compounds containing nitrogen are important category of heterocyclic compounds, which play a significant roles in modern pesticide industry (85% of pesticides with high activity and low toxicity contain nitrogen heterocyclic compound) [1]. Pyrazoles are important moieties as building blocks for many heterocyclic products and act as abinucleophile [2] with abroad spectrum of remarkable biological activities.…”

BackgroundSome novel substituted pyrazolone, pyrazolo[3,4-c]pyridazine, pyrazolo[3,4-d]pyrimidine, pyrazolo[3,4-d]thiazolo[3,2-a]pyrimidinone, thieno[3,2-c]pyrazole and pyrazolo[3′,4′:4,5]thieno[2,3-d]pyrimidine derivatives have been reported to possess various pharmacological activities like antimicrobial, antitumor and anti-inflammatory.ResultsA novel series of azoles and azines were designed and prepared via reaction of 1,3-diphenyl-1H-pyrazol-5(4H)-one with some electrophilic and nucleophilic reagents. The structures of target compounds were confirmed by elemental analyses and spectral data.ConclusionsThe antimicrobial activity of the target synthesized compounds were tested against various microorganisms such as Escherichia coli; Bacillus megaterium; Bacillus subtilis (Bacterial species), Fusarium proliferatum; Trichoderma harzianum; Aspergillus niger (fungal species) by the disc diffusion method. In general, the novel synthesized compounds showed a good antimicrobial activity against the previously mentioned microorganisms.

“…The herbicidal evaluation of compounds 3 was carried out in the laboratory of biological activities test, State Key Laboratory of Elemento‐organic Chemistry, Nankai University, China. Compounds 3 were determined with B. campestris L. and E. crus‐galli as samples of annual dicotyledonous and monocotyledonous plants, respectively, using a previously reported procedure [16]. For all of the bioassay tests, each treatment was repeated twice.…”

A series of novel acylpyrazole derivatives containing 1,2,3‐thiadiazole ring 3a–3m were synthesized by the condensations of 1‐phenyl‐3‐methyl‐4‐(substituted benzal or 4‐methyl‐1,2,3‐thiadiazole‐5‐carbonyl)‐5‐hydroxypyrazole 2 with 4‐methyl‐1,2,3‐thiadiazole‐5‐carbonyl chloride or substituted benzoyl chloride. Their structures were confirmed by IR, 1H‐NMR, mass spectroscopy, and elemental analyses. The results of preliminary bioassays showed that some of the title compounds 3 exhibited moderate to good herbicidal activities against dicotyledonous plants (Brassica campestris L.) at the concentration of 100 mg/L. For example, compounds 3e, 3f, 3g, and 3k possessed 74.6%, 72.2%, 70.3%, and 84.5% inhibition against B. campestris L., respectively, whereas commercially available herbicide Sulcotrione showed only 35.0% inhibition at the same concentration. Moreover, these compounds displayed higher herbicidal activity against B. campestris L. than Echinochloa crus‐galli. However, these compounds showed weak activities at the concentration of 10 mg/L.
