| 15 | Arylated analogues of cypronazole: fungicidal effect and activity on human fibroblasts. Docking analysis and molecular dynamics simulations显示文摘Triadimefon(TDM)and cyproconazole(CPZ)are two triazoles widely used as fungicides.Several azoles were synthe-sised starting from commercial TDM and CPZ.The compounds were evaluated against phytopathogenic filamentous fungi,including Aspergillus fumigatus(AF),A.niger(AN),A.ustus(AU),A.japonicus(AJ),A.terreus(AT),Fusarium oxyspo-rum and Botrytis cinerea isolated from grapevine in the province of San Juan,Argentina.Three of the synthesised compounds(1-(Biphenyl-4-yloxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-one,1;2-(Biphenyl-4-yl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol,3;3-Cyclopropyl-2-(4’-fluorobiphenyl-4-yl)-1-(1H-1,2,4-triazol1-yl)butan-2-ol,4)presented remarkable in vitro fungicidal properties,with better effects than TDM and CPZ on some of the target fungi.Cytotoxicity was assessed using human lung fibroblasts MRC5.Derivative 1,with IC50 values of 389.4μM,was less toxic towards MRC-5 human lung fibroblasts than commercial TDM(248.5μM)and CPZ(267.4μM).Docking analysis and molecular dynamics simulations suggest that the compounds present the same interaction in the binding pocket of the CYP51B enzyme and with the same amino acids as CPZ.The derivatives investigated could be considered broad-spectrum but with some selectivity towards imperfect fungi. | Natividad Herrera Cano Sebastian A.Andujar Cristina Theoduloz Daniel A.Wunderlin Ana N.Santiago Guillermo Schmeda-Hirschmann Ricardo D.Enriz Gabriela E.Feresin | 2022 | Natural Products and Bioprospecting2022，12，1： | 0 |
