The article was titled 《Synthesis, insecticidal evaluation and 3D-QSAR study of novel anthranilic diamide derivatives as potential ryanodine receptor modulators》. The information in the text is summarized as follows:

BACKGROUND : Anthranilic diamide insecticides control lepidopteran pests through selectively binding and activating insect ryanodine receptors. In order to search for potential insecticides targeting the ryanodine receptors, a series of anthranilic diamide analogs including trifluoromethyl, nitro, or chloro groups were designed and synthesized by the principle of bioisosterism and structural optimization. RESULTS : Insecticidal data indicated that some compounds displayed good activity against oriental armyworm (Mythimna separata) and diamondback moth (Plutella xylostella). In particular, the larvicidal activity of 6p against P. xylostella was 95% at 0.01 mg L-1, equivalent to chlorantraniliprole (85%, 0.01 mg L-1). The comparative mol. similarity index anal. model obtained indicated that hydrogen bond acceptor and electron-withdrawing groups in the R’3 group are favorable for insecticidal activity against M. separata, which is consistent with the structure-activity relationships. Moreover, the calcium imaging experiment indicated, like chlorantraniliprole, that 6h and 6p are interacting with the ryanodine receptor. CONCLUSION : Introducing trifluoromethyl, nitro, or chloro groups to a specific position in the N-phenylpyrazole could improve or maintain the activity against M. separata and P. xylostella. 6h and 6p could be used as potential lead compounds for ryanodine receptor modulators.Μ.

Alepee, Nathalie; Grandidier, Marie-Helene; Cotovio, Jose published an article on February 28 ,2019. The article was titled 《Usefulness of the EpiSkin reconstructed human epidermis model within Integrated Approaches on Testing and Assessment (IATA) for skin corrosion and irritation》, and you may find the article in Toxicology In Vitro.Synthetic Route of C6H3ClFNO2 The information in the text is summarized as follows:

Predictive capacity of the EpiSkin model was evaluated on 87 chems. using the Bottom-Up and the Top-Down testing approaches recommended within Integrated Approach on Testing and Assessment for the identification of both skin irritation and corrosion hazards. Classified (UN GHS Cat. 1 and Cat. 2) chems. were identified with a very high sensitivity (≥94%) and the non-classified (UN GHS Cat. 3 and No Cat.) chems. with an appropriate specificity (70%). Very high sensitivities were obtained for the identification of Cat. 1 chems. (≥98%), very high specificities for non-Cat. 1 chems. (93%), and accuracies of -95% for the identification of skin corrosives vs. non-corrosives by both approaches. Overall accuracies of 72% were found for predicting the single (sub)categories: non-classified, Cat. 2, Subcat. 1B/1C and Subcat. 1A. Results indicated the testing strategies to be more predictive than the individual assays on a conservative safety approach. Finally, no extreme misclassifications (no under-prediction of in vivo Subcat. 1A as non-Cat. 1, and no over-prediction of non-classified chem. as Subcat. 1A) occur. These findings, independently of the approach used, confirm the usefulness of the EpiSkin in vitro model for a safe prediction of the skin irritant and corrosive hazards of chems. In addition to this study using 3-Chloro-4-fluoronitrobenzene, there are many other studies that have used 3-Chloro-4-fluoronitrobenzene(cas: 350-30-1Synthetic Route of C6H3ClFNO2) was used in this study.

3-Chloro-4-fluoronitrobenzene(cas: 350-30-1) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Synthetic Route of C6H3ClFNO2

Quality Control of 3-ChlorobenzylchlorideOn September 30, 2019 ,《New potent antifungal triazole alcohols containing N-benzylpiperazine carbodithioate moiety: Synthesis, in vitro evaluation and in silico study》 was published in Bioorganic Chemistry. The article was written by Mahmoudi, Yaser; Badali, Hamid; Hashemi, Seyedeh Mahdieh; Ansari, Mahsa; Fakhim, Hamed; Fallah, Marjan; Shokrzadeh, Mohammad; Emami, Saeed. The article contains the following contents:

A number of 1H-1,2,4-triazole alcs. containing N-(halobenzyl)piperazine carbodithioate moiety were designed and synthesized as potent antifungal agents. In vitro bioassays against different Candida species including C. albicans, C. glabrata, C. parapsilosis, C. krusei, and C. tropicalis revealed that the N-(4-chlorobenzyl) derivative(I) with MIC values of 0.063-0.5μg/mL had the best profile of activity, being 4-32-fold more potent than fluconazole. Docking simulation studies confirmed the better fitting of I deriv in the active site of lanosterol 14α-demethylase (CYP51) enzyme, the main target of azole antifungals. Particularly, the potential of I against fluconazole-resistant isolates along with its minimal toxicity against human erythrocytes and HepG2 cells make this prototype compound as a good lead for discovery of potent and safe antifungal agents.

The article conveys some information:

This work presented the first report on designing, synthesizing of novel pyrazole-triazole-persulfonimide and pyrazole-triazole-aryl derivatives via click reaction using CuI catalyst and evaluated for their anti-diabetic activity and DPP-4 inhibitory effect. Click reactions went smoothly with CuI catalyst in the presence of tridentate chelating ligands and produced copper-free target pyrazole-triazole-persulfonimide analogs in excellent yield at RT. The designed compounds were docked against DPP-4 enzyme and showed excellent interaction with active amino acids residue. Further, all novel pyrazole-triazole-persulfonimide and pyrazole-triazole derivatives were subjected to enzyme-based in vitro DPP-4 inhibitory activity. Based on the SAR study DPP-4 inhibitory capacity compounds 6N-((1-(3-((1,3-diphenyl-1H-pyrazol-5-yl)oxy)propyl)-1H-1,2,3-triazol-4-yl)methyl)4-methyl-N-(3-nitrobenzyl)benzenesulfonamide (9.52 nM) and 8h (4.54 nM) possessed the significant inhibition of DPP-4.

In 2022,Che, Zhiping; Guo, Xiaolong; Li, Yuanhao; Zhang, Song; Zhu, Lina; He, Jiaxuan; Sun, Di; Guo, Yihao; Liu, Yibo; Wei, Ruxue; Huang, Xiaobo; Liu, Shengming; Chen, Genqiang; Tian, Yuee published an article in Pest Management Science. The title of the article was 《Synthesis of paeonol ester derivatives and their insecticidal, nematicidal, and anti-oomycete activities》.Safety of Thiophene-2-sulfonyl chloride The author mentioned the following in the article:

Paeonol is extracted and isolated as a rich and sustainable natural bioresource from the root bark of Paeonia suffruticosa, the derivatives of which exhibit numerous biol. activities. It is well known that ester compounds play a very important role in pest control, such as organophosphorus, carbamate and pyrethroid pesticides. To discover biorational natural product-based pesticides, three series of (60) paeonol ester derivatives (7a-t, 8g,p, 9g,p, 10g-j,n-u, 11g,u, 12g,u, 13a-p, 14b,c, and 15b,c) were prepared by structural modification of paeonol, and their structures were well characterized by proton NMR (1H-NMR), carbon-13 NMR (13C-NMR), high-resolution mass spectrometry (HRMS), and m.p. Furthermore, we assessed the compounds as insecticidal, nematicidal, and anti-oomycete agents against three serious agricultural pests, Mythimna separata, Heterodera glycines, and Phytophthora capsici. Among all tested compounds: (i) compound 8p showed more significant insecticidal activity than toosendanin, and the final mortality rates of 8p and toosendanin against M. separata (1 mg mL-1) were 70.4%, and 51.9%, resp.; (ii) compound 7a exhibited more promising nematicidal activity than paeonol, and the median lethal concentration (LC50) values of 7a and 1 against H. glycines were 15.47 and 50.80 mg L-1, resp.; (iii) compounds 7n and 13m displayed more significant anti-oomycete activity compared to zoxamide against Phytophthora capsici, and the median effective concentration (EC50) values of 7n, 13m, and zoxamide were 23.72, 24.51, and 26.87 mg L-1, resp.; and the protective effect of the compounds against Phytophthora capsici in vivo further confirmed the effectiveness of the agents. This study suggested that the introduction of a nitro at the C5 or C3 position of paeonol could improve its bioactivity against M. separata, H. glycines, and Phytophthora capsici.
