However, the long-term application of HPPD inhibitors with in their classical scaffolds inevitably leads to the development of drug resistance. To further delay the underlying development of weed resistance to HPPD inhibitors, we successfully screened HPPD inhibitor pharmacophore with novel chelate structures using computer-aided drug molecular design and obtained 2-trifluoromethyltetrazolium nicotinamide derivatives through active fragment splicing. Among these derivatives, 6-(3,3-diethyl-1-methylureido)-<em>N</em>-(1-methyl-1<em>H</em>-tetrazol-5-yl)-2-(trifluoromethyl)nicotinamide (compound <strong>31</strong>), exhibited the most promising <em>in vitro</em> enzyme inhibitory activity, with IC₅₀ value of 0.072 μM, which was approximately five times better than that of the control agent mesotrione (IC₅₀ = 0.363 μM). The crystal structure of the <em>At</em>HPPD complexed with compound <strong>31</strong> (2.0 Å) and the binding energy calculations of the representative compounds revealed several important interactions of the ligand binding to the target protein, which explained the superior enzyme inhibitory activity of the compounds at the molecular level. In addition, compounds <strong>7</strong> and <strong>31</strong> possessed 100% inhibition against the five target weeds at the tested dosage and both were more effective against <em>Setaria viridis</em> than mesotrione. In general, it is promising to design novel HPPD inhibitors by developing novel chelating structures, and compounds <strong>7</strong> or <strong>31</strong> could be used as the leads for further development of valuable HPPD inhibitors.</p></div>","PeriodicalId":100027,"journal":{"name":"Advanced Agrochem","volume":"2 2","pages":"Pages 163-172"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49726958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the title compounds also showed remarkable larvicidal activity against <em>M. separata</em> and some compounds exhibited good aphicidal activity.

In this review, we summarize the most recent progress on the development of fluorescent probes for selectively detecting BAs, nitrite, and sulfite. In particular, we discuss the working mechanisms, sensing performance, and practical applications of various fluorescent probes that have been developed in recent years for detecting BAs, nitrite, and sulfite, with a particular emphasis on the utilization of these probes in food.

Particularly, it is highlighted that fullerenes, carbon nanotubes, graphenes, and their functionalized forms as the representative zero-, one-, and two-dimensional GCNMs in optimum quantity have favorable efficacy on plants for seed germination, growth and development, fruit and productivity, and stress tolerance. On the contrary, GCNMs have possibly induced cytotoxicity and phytotoxicity on plant at anatomic, physiological, and genetic levels. The toxic mechanisms were mainly attributed to ion leakage from membrane, chloroplast damage, decreasing the levels of photosynthetic/nonphotosynthetic pigments and plant hormones, downregulating activities of metabolism and enzymatic/non-enzymatic antioxidant systems, or triggering ROS increase for inducing oxidative stress.
