A series of isosteric analogs of mandipropamid were designed and synthesized via 'click chemistry'. The amide bond of mandipropamid was substituted by a 1,2,3-triazole functional group. The bioassay results have indicated that some of the title compounds exhibited moderate fungicidal activity against Pseudoperonospora cubensis, and the activity has been systematically studied as a function of molecular structure. The low activity of the mandipropamid analog that contains a lipid chain is likely due to the presence of a weak hydrogen bond donor in the 1,2,3-triazole. Furthermore, we have performed the molecular modeling and found that N-methylamide could be more effective than amide as the surrogates to 1,2,3-triazole, which ultimately leads to a longer distance (1.1A longer) between the two substitutes in the 1,4-disubstituted 1,2,3-triazole compound.
