Evans, J. D. H. L.; Cavell, B. D.; Hignett, R. R. published the artcile< Fomesafen - metabolism as a basis for its selectivity in soya>, Computed Properties of 35852-58-5, the main research area is fomesafen metabolism herbicide soybean.

Soya, maize and spiny cocklebur (Xanthium spinosum) plants were treated with 14C-side-chain labeled fomesafen (Ia) by injection and or by root uptake from nutrient solution It was established that the facile metabolism of the compound in soya, but not the other species, was the basis for its herbicidal selectivity. Excised soya leaves were treated with aqueous solutions containing Ia, 14C-nitrophenyl-labeled fomesafen (Ib) and 14C-halophenyl-labeled fomesafen (Ic). The same major radioactive metabolite, M1 was formed following treatments with Ia and Ib but treatment with Ic yielded 2 different metabolites, M2 and M3. Therefore cleavage at the di-Ph ether linkage was proven. Metabolites M2 and M3 hydrolyzed with acid to 2-chloro-4-trifluoromethylphenol. Metabolite M1 was shown by cochromatog. to be S-[3-(N-methanesulfonylcarbamoyl)-4-nitrophenyl]cysteine.

A strategy to functionalized spiro[4.5]trienones I [R = Ph, 2-thienyl, 1-naphthyl, etc.; R1 = Me, Bn, Ts, etc.; R2 = H, 7-Me, 7-F, etc.; R3 = Me, C(O)Me, C(O)Ph, etc.] by domino silver-catalyzed decarboxylative acylation or alkylation/ipso-cyclization of N-arylpropiolamides with α-keto acids/alkyl carboxylic acids was presented. This transformation offered a wide range of substituted 3-acyl/alkyl-spiro[4.5]trienones in high yields with a broad substrate scope. The approach was further extended to access fused tricyclic frameworks, 6,7-dihydro-3H-pyrrolo[2,1-j]quinoline-3,9(5H)-diones II [R4 = Ph, 4-ClC6H4, 4-AcC6H4; R5 = t-Bu, C(O)Et, C(O)Ph, etc.].

Chen, Lijuan; Wang, Xiaobin; Tang, Xu; Xia, Rongjiao; Guo, Tao; Zhang, Cheng; Li, Xiangyang; Xue, Wei published the artcile< Design, synthesis, antiviral bioactivities and interaction mechanisms of penta-1,4-diene-3-one oxime ether derivatives containing a quinazolin-4(3H)-one scaffold>, Application of C7H6Cl2, the main research area is tobacco mosaic virus pentadieneone oxime ether quinazolinone antiviral; Antiviral activity; Interaction mechanisms; Molecular docking study; Oxime ether; Penta-1,4-diene-3-one; Quinazolin-4(3H)-one; Tobacco mosaic virus.

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.

Zhao, Xuelian; Zhan, Xuehui; Zhang, Huilin; Wan, Yichao; Yang, Huizhong; Wang, Yutian; Chen, Yanda; Xie, Wenlin published the artcile< Synthesis and biological evaluation of isatin derivatives containing 1,3,4-thiadiazole as potent a-glucosidase inhibitors>, Safety of 1-Chloro-2-(chloromethyl)benzene, the main research area is thiadiazolylhydrazono benzyloxindole preparation diastereoselective glucosidase inhibition kinetics SAR docking; 1,3,4-Thiadiazole; Isatin; Triethyl orthoformate; α-Glucosidase.

A series of isatin derivatives containing 1,3,4-thiadiazole derivatives I [R = 2-F, 3-CN, 4-Cl, etc.] were designed and synthesized. All newly synthesized compounds I were evaluated for their α-glucosidase inhibitory activity with resveratrol as pos. control in-vitro. Except for compounds I [R = 2-CN, 3-CN], all of the compounds I showed a potent inhibitory activity against α-glucosidase with IC50 values in the range of 3.12 ± 1.25 to 45.95 ± 1.26μM and the purity of these compounds were greater than 95%. The IC50 values were being compared to the standard resveratrol (IC50 = 22.00 ± 1.15μM) and it was found that compounds I [R = H, 2-F, 2-Cl, 3-Cl, 4-Cl, 2-Br] were found to be more active than resveratrol. Specifically,I [R = 4-Cl] exhibited the most potent α-glucosidase inhibitory activity with IC50 value of 3.12 ± 1.25μM. The kinetic anal. revealed that compound I [R = 4-Cl] was noncompetitive inhibitor. Structure activity relationship was established for all compounds I. Furthermore, the binding interactions of compound I [R = 4-Cl] with the active site of α-glucosidase were confirmed through mol. docking. This study was identified a new class of potent α-glucosidase inhibitors for further investigation.

Terasaki, Masanori; Makino, Masakazu published the artcile< Determination of chlorinated by-products of parabens in swimming pool water>, Product Details of C8H7ClO3, the main research area is chlorinated byproduct paraben swimming pool water pollution.

We describe the determination of trace amounts of chlorinated parabens, i.e. disinfection byproducts, in swimming pool water, using gas chromatog.-mass spectrometry with selected ion monitoring (GC-MS-SIM). A dichlorinated byproduct of isopropylparaben was detected at levels of ≤25 ng/L. A dichlorinated byproduct of methylparaben and a monochlorinated byproduct of benzylparaben were present in concentrations lower than the limit of quantification. Benzylparaben, the parent compound, was also detected at concentrations ≤28 ng/L. In this study, chlorinated parabens were detected and quantified for the 1st time as disinfection byproducts in swimming pool water. The results have raised concerns regarding the chlorinated byproducts of active ingredients used in personal care products.

Ju, Changha; Kang, Shinwoo; Kim, Taehyung; Park, Chanhyuk; Kang, Hyo published the artcile< Vertical liquid crystal alignment of comb-like alkyl hydroxybenzoate-substituted polystyrene>, Reference of 1592-20-7, the main research area is alkyl hydroxybenzoate polystyrene vertical liquid crystal alignment.

We investigated the liquid crystal (LC) alignment behaviors of Bu hydroxybenzoate-substituted polystyrene (PBHB#; # = 20, 40, 60, 80, and 100, where # indicates the molar fraction of Bu hydroxybenzoate in the side chain), Me hydroxybenzoate-substituted polystyrene (PMHB100), and Et hydroxybenzoate-substituted polystyrene (PEHB100). Generally, LC cells made employing polymer films having longer alkyl groups in the side chain show vertical LC alignment. For instance, a LC cell fabricated with the PMHB100 film showed random planar LC alignment, while the LC cells made from the PEHB100 and PBHB100 films exhibited vertical LC alignment. Moreover, LC cells prepared from a polymer film having a higher molar content of Bu hydroxybenzoate in the side chain exhibited vertical LC alignment. The observed vertical LC alignment behaviors are closely related to the surface energy of these polymer films. For instance, vertical LC alignment was observed when the surface energy of the polymer film was less than ∼43.86 mJ/m2, which could result from the nonpolar alkyl groups of the alkyl hydroxybenzoate moiety. The LC cell prepared from PBHB100 as the LC alignment layer showed good electro-optical characteristics such as voltage holding ratio, residual DC voltage, and alignment stability at 200°C.

A new photosensitive polyimide (PI) was successfully synthesized via esterification of PI containing hydroxyl groups with cinnamoyl chloride (CL). The cinnamate (CA) group contents of the PI was up to 90%. The PI films could induce uniform parallel alignment of liquid crystal (LC) mols. after the non-polarized UV ageing lamp exposure, which reduce the cost significantly compared with polarized UV light equipment. In addition, the PI exhibited good thermal stability. Meanwhile, the possible mechanism of PI alignment films induced by NPUVL was discussed in some detail.
