Early in this research, cyclic amines substituted with (hetero)aryl(oxy) moieties were designed as target molecules and diversely synthesized, and 4-[4-(trifluoromethyl)phenoxy]-1-[5-(trifluoromethyl)-2-pyridyl]piperidine was found to show weak acaricidal activity. The structural optimization of this acaricidal active piperidine as the first lead compound led to the discovery of acynonapyr.

Flupentiofenox exerted significant acaricidal activities against spider mites Tetranychus urticae and Panonychus citri at all developmental stages even at extremely low concentrations, as compared with its practical concentration (80 ppm) for use in mites and was effective against spider mite populations that are resistant to widely used commercial acaricides. These results suggested that flupentiofenox could be used effectively for the control and prevention of spider mite infestation. Additionally, flupentiofenox had a more rapid effect than acetyl CoA carboxylase inhibitors, but it had a relatively slower effect than mitochondrial electron transport inhibitors and glutamate-gated chloride channel modulators. Overall, flupentiofenox is assumed to have a new mode of action.","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, pesticides traditionally have been tested on animals without human data, making validation difficult. Direct application of AOP-based models to pesticides may be inappropriate since their original applicability domains were designed to maximize reliability for human response prediction on diverse chemicals but not pesticides. This study proposed to identify a consensus chemical space with concordant human responses predicted by the SkinSensPred online tool and animal testing data to reduce animal testing. The identified consensus chemical space for non-sensitizers achieved high concordance of 85% and 100% for the cross-validation and independent test, respectively.
