甲氧基丙烯酸酯类杀菌剂作用机理研究进展 总被引:11,自引:0,他引:11
本文综述了甲氧基丙烯酸酯类杀菌剂(Strobilurins)的研究进展,包括这类杀菌剂的开发、作用机制及抗药性研究。这类杀菌剂活性高,杀菌谱广,而且对环境友好。这类杀菌剂作用于真菌线粒体的电子传递链的复合物Ⅲ,阻止电子传递,抑制能量合成。由于作用位点单一,易产生抗药性,其抗药性机制主要是细胞色素b基因序列上发生点突变。 相似文献

Succinate‐ubiquinone oxidoreductase (SQR, EC 1.3.5.1), also known as mitochondrial respiratory complex II or succinate dehydrogenase (SDH), catalyzes the oxidation of succinate to fumarate as part of the tricarboxylic acid cycle. SQR has been identified as a novel target of a large family of agricultural fungicides. However, the detailed mechanism of action between the fungicides and SQR is still unclear, and the bioactive conformation of fungicides in the SQR binding pocket has not been identified. In this study, the kinetics of porcine SQR inhibition by ten commercial carboxamide fungicides were measured, and noncompetitive inhibition was observed with respect to succinate, DCIP, and cytochrome c, while competitive inhibition was observed with respect to ubiquinone. With the aim to uncover the binding conformation of these fungicides, molecular docking, molecular dynamics simulation, and molecular mechanics/Poisson–Boltzmann surface area (MM/PBSA) calculations were then performed. The excellent correlation (r2=0.94) between the calculated (ΔGcal) and experimental (ΔGexp) binding free energies indicates that the obtained docking conformation could be the bioactive conformation. The acid moiety of carboxamide fungicides inserts into the ubiquinone binding site (Q‐site) of SQR, forming van der Waals (vdW) interactions with C_R46, C_S42, B_I218, and B_P169, while the amine moiety extends to the mouth of the Q‐site, forming vdW interactions with C_W35, C_I43, and C_I30. The carbonyl oxygen atom of the carboxamide forms hydrogen bonds with B_W173 and D_Y91. These findings provide valuable information for the design of more potent and specific inhibitors of SQR. 相似文献
