In this paper, a dual-functional probe, 2-(benzothiazol)-4-(3-hydroxy-4-methylphenyl) imino phenol (BHMH), was synthesized and characterized for the simultaneous detection of Cu2+ Fe3+ in dimethyl sulfoxide/4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (DMSO/HEPES) (1:4, v/v, pH = 6.0). The limits detections (LODs) were 9.05 48 nM, respectively. Based on competitive coordination, complex BHMH-Cu2+/Fe3+ exhibited good sensitivity selectivity glyphosate. LODs BHMH-Cu2+ BHMH-Fe3+ glyphosate 0.41 0.63 μM, probe quantitatively detected tap water, Songhua River local water soil, food samples. colorimetric on-site sensing through also studied based smartphones. BHMH outstanding imaging capabilities Cu2+, Fe3+, living cells with low cytotoxicity, especially first time

Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is an important target for discovering novel herbicides, and it causes bleaching symptoms by inhibiting the synthesis of chlorophyll heme. In this study, active fragments several commercial herbicides were joined substructure splicing bioisosterism, a series diphenyl ether derivatives containing five-membered heterocycles synthesized. The greenhouse herbicidal activity PPO inhibitory in vitro discussed detail. results showed that most compounds had good activity, trifluoromethyl groups tended to have higher activity. Among them, compound G4 best with half-maximal concentration (IC50) 0.0468 μmol/L, which was approximately 3 times better than oxyfluorfen (IC50 = 0.150 μmol/L). addition, molecular docking indicated formed obvious π-π stacking interactions hydrogen bond PHE-392 ARG-98, respectively. Remarkably, safety corn, wheat, rice, soybean, cumulative crops lower oxyfluorfen. Therefore, can be used develop potential lead inhibitors.

Fabrication and Characterization of Antifungal Hydroxypropyl-β-Cyclodextrin/Pyrimethanil Inclusion Compound Nanofibers Based on Electrospinning

Journal of Agricultural and Food Chemistry, Journal Year: 2022, Volume and Issue: 70(26), P. 7911 - 7920

Published: June 24, 2022

Pyrimethanil (PMT) is an anilinopyrimidine bactericide with poor water solubility, which limits its applications. To improve the physical and chemical properties of PMT, hydroxypropyl-β-cyclodextrin/pyrimethanil inclusion compound nanofibers (HPβCD/PMT-IC-NFs) were fabricated via electrospinning. A variety analytical techniques used to confirm formation compound. Scanning electron microscopy image displayed that HPβCD/PMT-IC-NF was homogeneous without particles. Thermogravimetric analysis indicated improved thermostability PMT. In addition, phase solubility test illustrated formed by PMT HPβCD had a stronger solubility. The antifungal effect exhibited better properties. release experiment confirmed sustained-release effect, curve conformed first-order kinetic model equation. short, fabrication inhibited thus promoting development pesticide dosage form water-based low-pollution direction.
