A series of 1,3,4-oxadiazole contained sesquiterpene derivatives were synthesized, and the activity of the target compounds against Xanthomonas oryzae pv. oryzae (Xoo), Xanthomonas axonopodis pv. citri (Xac), and tobacco mosaic virus (TMV) were evaluated. The biol. activity results showed that the EC₅₀ values of compounds H4, H8, H11, H12, H14, H16, and H19 for Xac inhibitory activity were 33.3, 42.7, 56.1, 74.5, 37.8, 43.8, and 38.4 μg/mL, resp. Compounds H4, H8, H15, H19, H22, and H23 had inhibitory effects on Xoo, with EC₅₀ values of 51.0, 43.3, 43.4, 50.5, 74.6, and 51.4 μg/mL, resp. In particular, the curative and protective activities of compound H8 against Xoo in vivo were 51.9 and 49.3%, resp. In addition, the EC₅₀ values of the inactivation activity of compounds H4, H5, H9, H10, and H16 against TMV were 69.6, 58.9, 69.4, 43.9, and 60.5 μg/mL, resp. The results of mol. docking indicated that compound H10 exhibited a strong affinity for TMV-coat protein, with a binding energy of -8.88 kcal/mol. It may inhibit the self-assembly and replication of TMV particles and have an anti-TMV effect, which supports its potential usefulness as an antiviral agent.

Chen, Shuming published the artcileArylketone π-Conjugation Controls Enantioselectivity in Asymmetric Alkynylations Catalyzed by Centrochiral Ruthenium Complexes, Product Details of C8H4ClF3O, the publication is Journal of the American Chemical Society (2018), 140(15), 5146-5152, database is CAplus and MEDLINE.

The origin of enantioselectivity in the asym. alkynylation of trihalomethyl ketones catalyzed by octahedral stereogenic-at-ruthenium complexes has been investigated through d. functional theory calculations Computational results support a mechanism involving formation of a ruthenium acetylide, followed by pre-coordination of the trihalomethyl ketone through the carbonyl oxygen and intramol. attack of the acetylide via a compact four-membered transition state. Differences in computed free energies of activation for the formation of the major and minor propargyl alc. enantiomers are in good agreement with the exptl. observed levels of asym. induction. Anal. of fragment distortion energies shows that disfavored transition states are destabilized due to the more severe distortion and loss of π-conjugation in the coordinated arylketone fragments. Examination of the different substitution patterns in the ketone substrate and the catalyst reveals the key steric factors that control the enantioselectivity. Finally, calculations indicate promising directions for the simplification of the catalyst scaffold while preserving the high levels of enantioselectivity of these alkynylation reactions.

Han, Shuaiyuan published the artcileReversible Complexation Mediated Living Radical Polymerization Using Tetraalkylammonium Chloride Catalysts, Category: chlorides-buliding-blocks, the publication is Macromolecular Rapid Communications, database is CAplus and MEDLINE.

The paper reports the first use of organic chloride salts as catalysts for reversible complexation mediated living radical polymerization Owing to the strong halogen-bond forming ability of Cl^–, the studied four tetraalkylammonium chloride catalysts (R₄N⁺Cl^–) successfully control the polymerizations of Me methacrylate, yielding polymers with low dispersities up to high monomer conversion (>90%). Benzyldodecyldimethylammonium chloride is further exploited to other methacrylates and yields low-dispersity block copolymers. Advantages of the chloride salt catalysts are wide monomer scope, good livingness, accessibility to block copolymers, and good solubility in organic media. Because of the good solubility, the use of the chloride salt catalysts can prevent agglomeration of catalysts on reactor walls in organic media, which is an industrially attractive feature. Among halide anions, chloride anion is the most abundant and least expensive halide anion, and therefore, the use of the chloride salt catalysts may lower the cost of the polymerization

A promising method for preparation of the superparamagnetic and strongly magnetic Fe₃O₄@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compds was reported. The catalyst showed a high selectivity of greater than 96% and effectively inhibited the occurrence of the side reactions of dehalogenation and C-N coupling. The optimum condition of the hydroredn. reaction was when THF is used as solvent and the reaction occurred at 50° for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceeded 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling byproducts were produced in the brominated aromatic compound and the iodinated aromatic compound

Yang, Guangqian published the artcileStudy of the in vivo antiviral activity against TMV treated with novel 1-(t-butyl)-5-amino-4-pyrazole derivatives containing a 1,3,4-oxadiazole sulfide moiety, Quality Control of 939-99-1, the publication is Pesticide Biochemistry and Physiology (2021), 104740, database is CAplus and MEDLINE.

A series of new 1-tert-butyl-5-amino-4-pyrazole bioxadiazole sulfide derivatives containing a 1,3,4-oxadiazole moiety were designed and synthesized. The bioactivity results showed that some title compounds exhibited excellent protective activity against TMV and certain insecticidal activity. Among the tested compounds, the EC₅₀ values of 5d, 5j, 5k and 5l were 165.8, 163.2, 159.7 and 193.1 mg/L, resp., which are better than the EC₅₀ value of ningnanmycin (271.3 mg/L). The chlorophyll contents and the defense enzyme activities of the tobacco leaves after treatment with 5j were significantly increased, which indicated that this series of title compounds may induce the systemic acquired resistance of host to defend against diseases. Further in vivo protective activity research on 5j using TMV with a GFP gene tag found that it can effectively inhibit the spread of TMV in inoculated tobacco. A morphol. study with TEM revealed that title compound 5h can cause a distinct break of the rod-shaped TMV. Moreover, the insecticidal activity revealed that the fatality rates of 5a, 5b and 5m against aphidoidea were 85%, 83% and 87%, resp., which indicated that the title compounds can effectively block the common carrier of plant viruses, thereby effectively reducing the TMV infection risk of tobacco. This series of synergistic effects provide key information for the research and development of antiviral agents.

Wang, Guan published the artcileDiscovery of a Novel Dual-Target Inhibitor of ERK1 and ERK5 That Induces Regulated Cell Death to Overcome Compensatory Mechanism in Specific Tumor Types, Application of 3-Chlorobenzylchloride, the publication is Journal of Medicinal Chemistry (2020), 63(8), 3976-3995, database is CAplus and MEDLINE.

ERK1 and ERK5 are proposed to have pivotal roles in several types of cancer. Under some circumstance, ERK5 may provide a common bypass route, which rescues proliferation upon abrogation of ERK1 signaling. Thus, we accurately classified the tumor types from The Cancer Genome Atlas (TCGA) based on the expression levels of ERK1 and ERK5. We proposed a novel therapeutic strategy to overcome the above-mentioned compensatory mechanism in specific tumor types by co-targeting both ERK1 and ERK5. On the basis of the idea of overcoming ERK5 compensation mechanism, 22ac (ADTL-EI1712) as the first selective dual-target inhibitor of ERK1 and ERK5 was discovered to have potent antitumor effects in vitro and in vivo. Interestingly, this compound was found to induce regulated cell death accompanied by autophagy in MKN-74 cells. Taken together, our results warrant the potential of this dual-target inhibitor as a new candidate drug that conquers compensatory mechanism in certain tumor types.
