Succinate dehydrogenase inhibitor is a low-toxic and high active fungicide. In order to develop novel and broad-spectrum succinate dehydrogenase inhibitor (SDHI) fungicides, thiophene was introduced into the structure of pyrazole carboxamide fungicides. Twenty four pyrazole-thiophene carboxamides were designed, synthesized and characterized by <sup>1<\/sup>H NMR, <sup>13<\/sup>C NMR and HRMS. The crystal structure of N-(4-methoxyphenyl)-4-(1-methyl-1H-pyrazol-4-yl) thiophene-2-carboxamide (7i) was determined by X-ray diffraction. The antifungal activity of all the synthesized compounds was determined against six plant pathogenic fungi, and preliminary bioassays suggested that some compounds exhibited good antifungal activity against Rhizoctonia solani, Fusarium graminearum and Botrytis cinerea. Among them, N-(4-fluorophenethyl)-4-(1-methyl-1H-pyrazol-4-yl) thiophene-2-carboxamide (7c) exhibited the best antifungal activities against R. solani in vitro with EC<sub>50<\/sub> value of 11.6\u03bcmol\/L, and N-(2-fluorophenyl)-4-(1-methyl-1H-pyrazol-4-yl) thiophene-2-carboxamide (7j) against F. graminearum with EC<sub>50<\/sub> value of 28.9\u03bcmol\/L. And N-(4-chlorophenyl)-4-(1-methyl-1H-pyrazol-4-yl) thiophene-2-carboxamide (7h) showed similar inhibition abilities with thifluzamide against B. cinerea with EC<sub>50<\/sub> value of 21.3\u03bcmol\/L. The mol. docking results showed that the high antifungal activities compounds form stronger interactions with important amino acid residues of succinate dehydrogenase.<\/p>\n<p><a href=\"https:\/\/www.ambeed.com\/products\/761446-44-0.html\">Formula: C10H17BN2O2<\/a>, 1-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole is a useful research compound.
