penta-1,4-diene-3-one oxime ether and quinazolin-4(3H)-one derivatives possess favorable agricultural activities. Aiming to discover novel mols. with highly-efficient agricultural activities, a series of penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold were synthesized and evaluated for their antiviral activities. Antiviral bioassays indicated that some title compounds exhibited significant antiviral activity against tobacco mosaic virus (TMV). In particular, compounds 8c, 8j and 8k possessed appreciable curative activities against TMV in vivo, with half-maximal effective concentration (EC50) values of 138.5, 132.9 and 125.6 μg/mL, resp., which are better than that of ningnanmycin (207.3 μg/mL). Furthermore, the microscale thermophoresis experiments (MST) on the interaction of compound 8k with TMV coat protein (TMV CP) showed 8k bound to TMV CP with a dissociation constant of 0.97 mmol/L. Docking studies provided further insights into the interaction of 8k with the Arg90 of TMV CP. Sixteen penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold were designed, synthesized, and their antiviral activities against TMV were evaluated. Antiviral bioassays indicated that some target compounds exhibited remarkable antiviral activities against TMV. Furthermore, through the MST and docking studies, we can speculate that 8k inhibited the virulence of TMV by binding Arg90 in TMV CP. These results indicated that this kind of penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold could be further studied as potential alternative templates in the search for novel antiviral agents.

Zhang, Xiao published the artcileDesign, Synthesis, and Synergistic Activity of Eight-Membered Oxabridge Neonicotinoid Analogues, Category: chlorides-buliding-blocks, the publication is Journal of Agricultural and Food Chemistry (2021), 69(10), 3005-3014, database is CAplus and MEDLINE.

Insecticide synergists are sought-after due to their potential in improving the pesticide control efficacy with a reduced dose of an active ingredient. We previously reported that a cis-configuration neonicotinoid (IPPA08) exhibited specific synergistic activity toward neonicotinoid insecticides. In this study, we synthesized a series of structural analogs of IPPA08 by converting the pyridyl moiety of IPPA08 into Ph groups, via facile double-Mannich condensation reactions between nitromethylene compounds and glutaraldehyde. All of the oxabridged neonicotinoid compounds were found to increase the toxicity of imidacloprid against Aphis craccivora. Notably, compound (I) at 0.75 mg/L lowered the LC₅₀ value of imidacloprid against A. craccivora by 6.54-fold, while a 3.50-fold reduction of the LC₅₀ value was observed for IPPA08. The results of bee toxicity test showed that compound I display selectivity in its effects on imidacloprid toxicity against the honey bee (Apis mellifera L.). In summary, replacing the pyridyl ring with a Ph ring was a viable approach to obtain a novel synergist with oxabridged moiety for neonicotinoid insecticides.

Wang, Pei-Yi published the artcileRational Optimization and Action Mechanism of Novel Imidazole (or Imidazolium)-Labeled 1,3,4-Oxadiazole Thioethers as Promising Antibacterial Agents against Plant Bacterial Diseases, Safety of 3-Chlorobenzylchloride, the publication is Journal of Agricultural and Food Chemistry (2019), 67(13), 3535-3545, database is CAplus and MEDLINE.

The emergence and widespread occurrence of plant bacterial diseases that cause global production constraints have become major challenges to agriculture worldwide. To promote the discovery and development of new bactericides, imidazole-labeled 1,3,4-oxadiazole thioethers were first fabricated by integrating the crucially bioactive scaffolds of the imidazole motif and 1,3,4-oxadiazole skeleton in a single mol. architecture. Subsequently, a superior antibacterial compound A₆ was gradually discovered possessing excellent competence against plant pathogens Xanthomonas oryzae pv oryzae and Xanthomonas axonopodis pv citri with EC₅₀ values of 0.734 and 1.79 μg/mL, resp. These values were better than those of com. agents bismerthiazol (92.6 μg/mL) and thiodiazole copper (77.0 μg/mL). Further modifying the imidazole moiety into the imidazolium scaffold led to the discovery of an array of potent antibacterial compounds providing the corresponding min. EC₅₀ values of 0.295 and 0.607 μg/mL against the two strains. Moreover, a plausible action mechanism for attacking pathogens was proposed based on the concentration dependence of SEM, transmission electron microscopy, and fluorescence microscopy images. Given the simple mol. structures, easy synthetic procedure, and highly efficient bioactivity, imidazole (or imidazolium)-labeled 1,3,4-oxadiazole thioethers can be further explored and developed as promising indicators for the development of com. drugs.

Yuan, Huihui published the artcileA solvent-free method for the preparation of phosphinates from P(O)-OH compounds with alkyl chlorides, Name: 3-Chlorobenzylchloride, the publication is Tetrahedron Letters (2021), 153529, database is CAplus.

Herein, a new solvent-free synthetic method using P(O)-OH compound and alkyl chloride for phosphinate compounds is disclosed. This transformation proceeds smoothly under the promotion of a lone base and presents the advantages of an easily available raw material source, a simple post treatment process, good functional group tolerance and high reaction efficiency. Good yield was obtained when the reaction was magnified to gram scale(coating), and the molar ratio of P(O)-OH compounds and alkyl chlorides can be decreased to 1:2. This protocol provides a practical method for the preparation of phosphorus derivatives Furthermore, the reaction mechanism was explored by ³¹P NMR.

Various analogs of gatastatin I [Ar = 3-ClC₆H₄, 4-MeC₆H₄, 4-^tButC₆H₄, etc.], a γ-tubulin-specific inhibitor, were designed and synthesized by systematically optimizing the aromatic ring at the O⁷-benzyl group in accordance with an operational Topliss tree, and their biol. activities were evaluated. Some derivatives showed stronger cytotoxicity against HeLa cells than gatastatin. Especially, the cytotoxicity of the I [Ar = 3-ClC₆H₄] derivative was about 18-fold stronger than that of gatastatin. However, these derivatives did not exhibit binding ability to the yeast γ-tubulin small complex or inhibitory activity against α,β-tubulin polymerization These results suggested that γ-tubulin strongly recognized the unsubstituted Ph ring of the O⁷-benzyl group in gatastatin.

We have synthesized copper-incorporated KIT-5 mesoporous materials which were characterized thoroughly by powder x-ray diffraction, N₂-sorption, UV-Vis, HR-SEM & EDS and HR-TEM techniques. The low angle PXRD with theta values of 0.609, 0.660, 0.704 and 0.746 confirmed the mesoporosity of the synthesized materials. In addition, the materials showed type-IV isotherms which are spherical in morphol. and fringes with pores of materials supporting the formation of mesoporous materials. The catalytic activity of synthesized materials was also investigated. We have used our materials as catalyst for the synthesis of 1,2,3-triazole derivatives via three component reaction of alkyl/aryl halide, terminal alkynes and sodium azide in water as a solvent. The desired triazole products were obtained in very good yields. This study indicates the importance of Cu element, solid support with uniformity of metal nanoparticles over the materials. The recyclability study with PXRD data of the catalyst confirmed the existence of the mesoporosity of the catalyst after the reaction and the yield decreased marginally from 98 to 91% over three cycles. This reaction has broad substrate scope and is compatible for aliphatic, aromatic, allyl substrates giving high yield of triazole products.

New thiosemicarbazones I [R¹ = H, 3-Cl, 4-F, etc.; R² = H, OMe] were synthesized via condensation of N-benzylindole-3-carboxaldehydes with N⁴-substituted thiosemicarbazides in excellent yield. These thiosemicarbazones I were reacted with Et bromoacetate to produce original heterocyclic-substituted indole derivatives possessing a 4-oxo-thiazolidine group II. Anal. IR and NMR spectra and elemental anal. were performed to reveal their structures. The antimicrobial activity of all synthesized compounds was evaluated for antibacterial activity in vitro against Gram-pos. and Gram-neg. bacteria. Antibacterial screening data showed that two compounds I and II demonstrated activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. These preliminary results indicated that newly synthesized compounds such as I [R¹ = 3-Cl, R² = OMe] and II [R¹ = H, R² = H] showed a promising antibacterial potency.
