Thirty six 1-pyridyl-2-arylethenes XCH=CHArY (abbreviated XAEY) were synthesized, in which, X is 2-pyridyl, 3-pyridyl and 4-pyridyl, and Y is OMe, Me, H, Br, Cl, F, CF₃, and CN. Their UV absorption spectra were measured in anhydrous ethanol, and their wavelengths of absorption maximum, λ_max, were recorded. Also, 234 λ_max values of 1-substituted phenyl-2-arylethylene compounds (XAEY, where X is substituted phenyl) were collected. The excited-state substituent constants of three pyridyl groups and 23 substituted Ph groups (a total of 26) were obtained by means of the curve-fitting method. Taking the λ_max values of 358 samples of bi-arylethene derivatives as a data set and 126 samples of bi-aryl Schiff bases (including nine compounds synthesized by this work (data not shown)) as another data set, quant. correlation analyses were performed by employing the obtained excited-state substituent constants as a parameter, and good results were obtained for the two data sets. The reliability of the obtained excited-state substituent constant values was verified. The results of this paper provided excited-state substituent constants for the studied compounds and application of optical properties of conjugated organic compounds containing aryl groups.

Sixty-six samples of 1-furyl/thienyl-2-arylethylene model compounds XCH=CHArY (abbreviated XEBY) were synthesized. The NMR spectra (NMR) of model compounds were determined The chem. shift δ_C(X) and δ_C(Y) of the carbon atoms in bridging bond CH=CH which connected to the X group and the ArY group, resp., were confirmed with the two-dimensional NMR method. The effect of substituent on the δ_C(X) and δ_C(Y) was studied, meanwhile, the push-pull effect of substituent on Δδ_C = δ_C(Y) – δ_C(X) and δ_C(Y/X) = δ_C(Y)/δ_C(X) were discussed. The results show the following: (a) Both the δC(X) and δC(Y) are affected by excited-state substituent constant σCCexX of group X, Hammett constant σ(Y), and excited-state substituent constantσCCexY of group Y. The effect of σ(Y) on the δ_C(X) is pos., whereas that on the δ_C(Y) is neg. That is to say, the σ(Y) of group Y has an alternative influence on the δ_C(X) and δ_C(Y). (b) Compared with furyl, there is a p-d effect formed by the 3d orbit of S atom and the p electron of the π system in thienyl, which increase the chem. shift of the carbon atoms in bridging bond. (c) The push-pull effect between substituent X and Y is not only affected by the σ parameter but also related to the σ_CC^ex parameter, which results from the combined effect of the two parameters σ and σ_CC^ex. The observation of this paper provides a new perspective in understanding the push-pull effect of substituent.

Qi, Yan-yan published the artcileComparative efficacy of pharmacological agents on reducing the risk of major adverse cardiovascular events in the hypertriglyceridemia population: a network meta-analysis, Safety of Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Diabetology & Metabolic Syndrome (2021), 13(1), 15, database is CAplus and MEDLINE.

Hypertriglyceridemia (HTG) is considered an independent risk factor for major adverse cardiovascular events (MACE). This study analyzed the effects of various agents on MACE risk reduction in HTG (serum triglyceride �50 mg/dL) populations by performing a network meta-anal. We performed a frequentist network meta-anal. to conduct direct and indirect comparisons of interventions. PubMed, EMBASE, and the Cochrane library were searched for trials until Jul 6, 2020. Randomized controlled trials that reported MACE associated with agents in entire HTG populations or in subgroups were included. The primary outcome was MACE. Of the 2005 articles screened, 21 trials including 56,471 patients were included in the anal. The network meta-anal. results for MACE risk based on frequency data showed that eicosapentaenoic acid (EPA) (OR: 1.32; 95% CI 1.19-1.46), gemfibrozil (OR: 1.53; 95% CI 1.20-1.95), niacin plus clofibrate (OR: 2.00; 95% CI 1.23-3.25), pravastatin (OR: 1.32; 95% CI 1.15-1.52), simvastatin (OR: 2.38; 95% CI 1.55-3.66), and atorvastatin (OR: 0.55; 95% CI 0.37-0.82) significantly reduced the risk of MACE compared to the control conditions. In the subgroup anal. of HTG patients with triglycerides �200 mg/dL, bezafibrate (OR: 0.56; 95% CI 0.33-0.94), EPA (OR: 0.72; 95% CI 0.62-0.82), and pravastatin (OR: 1.33; 95% CI 1.01-1.75) significantly reduced the MACE risk. Simvastatin had a clear advantage in reducing the risk of MACE in the entire HTG population analyzed in this meta-anal. EPA, but not omega-3 fatty acid, was considered an effective HTG intervention. Among fibrates, gemfibrozil was most effective, though bezafibrate may significantly reduce the risk of MACE in populations with triglyceride levels of 200-300 mg/dL.

Sun, Sheng-Xin published the artcileDesign, synthesis, antifungal evaluation, and molecular docking of novel 1,2,4-triazole derivatives containing oxime ether and cyclopropyl moieties as potential sterol demethylase inhibitors, Name: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is New Journal of Chemistry (2021), 45(40), 18898-18907, database is CAplus.

In the search for novel sterol demethylase inhibitors (DMIs), a series of 1,2,4-triazole derivatives containing oxime ether and cyclopropyl moieties I (R = Ph, 2,4,6-trichlorophenyl, 2-(1,3-dimethoxy-3-oxoprop-1-en-2-yl)benzen-1-yl, etc.) were designed using the bioactive substructure combination assisted by virtual mol. docking. The antifungal evaluation against Rhizoctonia solani (Rs), Fusarium graminearum (Fg), and Botrytis cinerea (Bc) indicated that most of the target compounds exhibited remarkable inhibitory activities against the above-mentioned tested fungi. Significantly, the compound I (R = 2,6-dichlorophenyl) exhibited outstanding anti-Fg activity with an EC₅₀ value of 1.22μg mL^-1 in vitro, and a protective effect of 59.45% in vivo at 200μg mL^-1. Further investigation revealed that compound I (R = 2,6-dichlorophenyl) evidently inhibited Fg spore germination and caused some wrinkles and dents on the surface of mycelia. Mol. docking showed that compound I (R = 2,6-dichlorophenyl) bound with the target protein FgCYP51 via coordination, hydrogen bonding and stacking interactions that were similar, but slightly different from the interactions of tebuconazole with FgCYP51. These research results suggested that the target compounds I are valuable for the further structural optimization of novel triazole fungicides.

Sun, Shengxin published the artcileNovel (Z)/(E)-1,2,4-triazole derivatives containing oxime ether moiety as potential ergosterol biosynthesis inhibitors: design, preparation, antifungal evaluation, and molecular docking, Computed Properties of 939-99-1, the publication is Molecular Diversity, database is CAplus and MEDLINE.

Inspired by the highly effective and broad-spectrum antifungal activity of ergosterol biosynthesis inhibitions, a series of novel 1,2,4-triazole derivatives containing oxime ether moiety I (R = H, 4-CH₃, 3-F, etc.) were constructed for screening the bioactivity against phytopathogenic fungi. The (Z)- and (E)-isomers of target compounds were successfully separated and identified by the spectroscopy and single crystal X-ray diffraction analyses. The bioassay results showed that the (Z)-isomers of target compounds possessed higher antifungal activity than the (E)-isomers. Strikingly, the compound (Z)-I (R = 4-CF₃) exhibited excellent antifungal activity against Rhizoctonia solani with the EC₅₀ value of 0.41 μg/mL in vitro and preventive effect of 94.58% in vivo at 200 μg/mL, which was comparable to the pos. control tebuconazole. The SEM observation indicated that the compound (Z)-I (R = 4-CF₃) caused the mycelial morphol. to become wizened and wrinkled. The mol. docking modes of (Z)-I and (E)-I (R = 4-CF₃) with the potential target protein RsCYP51 were especially compared. And the main interactions between ligands and amino acid residues were carefully analyzed to preliminarily explain the mechanism leading to the difference of activity between two isomers. The study provided a new lead mol. skeleton for developing novel triazole fungicides targeting ergosterol biosynthesis.
