Design and Evaluation of Pyrazole Herbicides: QSAR-Driven Synthesis for Effective Weed Control and Crop Safety in Rice.

A total of twenty pyrazole derivatives were synthesized using alkoxy or halo acetophenones in reaction with N, N-dimethylformamide dimethylacetal (DMF-DMA). These compounds were characterized through 1H NMR, 13C NMR, and LC-HRMS techniques. Their herbicidal efficacy against barnyard grass (Echinochloa crus-galli) was e...

Green Synthesis, In Silico Molecular Docking, and Evaluation of Pyrazole Derivatives for Their Antifungal and Antinemic Activity

A series of 25 pyrazole derivatives was synthesized via ultrasonication‐assisted cyclization of chalcones with phenylhydrazine and characterized using 1H NMR, 13C NMR, and LC‐HRMS. Biological evaluation revealed that P‐25 [5‐(4‐fluorophenyl)‐1,3‐diphenyl‐1H‐pyrazole] exhibited the highest antifungal activity against Rh...
