Design, synthesis, and biological evaluation of phenyloxadiazole derivatives as potential antifungal agents against phytopathogenic fungi

Abstract: A novel series of picarbutrazox-inspired oxadiazole hybrids was synthesized and the derivatives’ biological activity against phytopathogenic fungi was investigated. The molecules were designed by retaining the active fragment of tetrazolyl phenyloxime ether of lead compound picarbutrazox, while introducing the potentially active oxadiazole-derived fragment. Bioassay results revealed that some of the title compounds showed potent in vivo antifungal activities to control cucumber downy mildew. Therefore, this novel oxadiazole phenyloxadiazole derivative can be used as a potential antifungal agent to control cucumber downy mildew and other phytopathogenic fungi for crop protection.

Synthesis, fungicidal activity, and 3D-QSAR of tetrazole derivatives containing phenyloxadiazole moieties

In an effort to discover new agents with good fungicidal activities against CDM (cucumber downy mildew), a series of tetrazole derivatives containing phenyloxadiazole moieties were designed and synthesized. The EC50 values for fungicidal activities against CDM were determined. Bioassay results indicated that most synthesized compounds exhibited potential in vivo fungicidal activity against CDM. A CoMFA (comparative molecular field analysis) model based on the bioactivity was developed to identify some primary structural quality for the efficiency. The values of q2 and r2 for the established model were 0.791 and 0.982 respectively, which reliability and predict abilities were verified. Three analogues (q3, q4, q5) were designed and synthesized based on the model. All these compounds exhibited significant fungicidal activity on CDM with the EC50 of 1.43, 1.52, 1.77 mg·L?1. This work could provide a useful instruction for the further structure optimization.

Phototransformation of tetrazoline oxime ethers: Photoisomerization vs. photodegradation

Fungicides showing potent biological activity in green house may have poor activity in the field due to fast photodegradation. This is the case of tetrazoline oxime ethers 1 and 2, active in the Z form, on which very little is known. A comprehensive study was therefore conducted to understand the photochemical behaviour of these compounds. It could be firmly demonstrated that both photoisomerization Z → E and photodegradation occur, and that interestingly photodegradation only takes place from E forms. Quantum yields of photoisomerization lay within the range 0.38-0.48 and those of E photodegradation in the range 0.06-0.11. During the reaction, the non-fungicidal E forms become the major isomers due to their lower solar light absorptivity than Z forms. The analytical study showed that photodegradation involves the cleavage of the N-O bond and allowed the identification of photoproducts arising from the rearrangement of the iminyl and alkoxyl radicals. Moreover, the proposed mechanism of alkoxyl radical oxidation into corresponding aldehyde and acid was elucidated using a computational study. This fundamental investigation fully explains the fast loss of the fungicidal activity of tetrazoline oxime ethers 1 and 2 in the field.
