Zhang, Meng; Wang, Fangfang; Ding, Wenjuan; Xu, Zhipeng; Li, Xiaosan; Tian, Danmei; Zhang, Youwei; Tang, Jinshan published the artcile< Synthesis of sorbicillinoid analogues with anti-inflammation activities>, Safety of (E)-Cinnamoyl chloride, the main research area is sorbicillinoid preparation antinflammatory SAR; Anti-inflammatory effects; LPS; NO production; Sorbicillinoids; Structural modification; iNOS.

The synthesis of a series of new sorbicillinoid I [R1 = R2 = R3 = H, 3-methylbut-2-enoyl, (2E,4E)-hexa-2,4-dienoyl, (E)-3-(4-chlorophenyl)prop-2-enoyl, etc.; R2 = R3 = Me] analogs was reported and assessed their anti-inflammatory activities. Results reveal that side chain substitution with (E)-2-butenoyl, (E)-3-(4-fluorophenyl)-2-propenoyl, and (E)-3-(3,4,5-trimethoxyphenyl)-2-propenoyl significantly enhanced the inhibitory effects of the derivatives on nitric oxide (NO) production and inducible NO synthesis (iNOS) expression stimulated by lipopolysaccharides (LPS) in mouse macrophage. Further chem. derivatization showed that the monomethylresorcinol skeleton worked better than the dimethylresorcinol skeleton in inhibiting LPS-induced inflammatory response in cultured cells. Among the synthesized sorbicillinoid analogs, compounds I [R1 = (E)-but-2-enoyl, R2 = R3 = Me; R1 = (E)-3-(3,4,5-trimethoxyphenyl)prop-2-enoyl, R2 = R3 = Me] exhibited the strongest anti-inflammatory activities, holding the promise of being developed into lead compounds that was explored as potent anti-inflammation agents.

Wu, Xiaofang; Zhou, Lei; Yang, Ruoqi; Guo, Fengzhe; Tang, Zi-Long; Xiao, Jing published the artcile< A practical chlorination of tert-butyl esters with PCl3 generating acid chlorides>, SDS of cas: 17082-09-6, the main research area is acid chloride preparation; tert butyl ester phosphorus trichloride chlorination.

For the first time, using PCl3, a range of tert-Bu esters is chlorinated successfully, allowing access of both aromatic acid chlorides and aliphatic acid chlorides RCOCl (R = Ph, 4-FC6H4, 4-MeC6H4, etc.) in good yields. The method features simple reaction conditions and wide substrate scope. Various tert-Bu esters including aryl esters, alkenyl esters, and alkyl esters were tolerated well in the reaction. A plausible mechanism is proposed.

At 265-360°, a variety of aromatic acyl chlorides can be rapidly decarbonylated to the corresponding aromatic chlorides in the gas phase or in the melt in moderate-to-excellent yield using 5% Pd/C, Pd(PPh3)4, or PdCl2 as a catalyst. E.g., trimellitic anhydride acid chloride in the melt with 5% Pd/C at 310° for 2 h gave 100% 4-chlorophthalic anhydride. 4-RC6H4COCl (R = H, Cl, CN, MeO, Me) with 5% Pd/C at 360° (gas phase) gave 18-98% 4-RC6H4Cl (R as before).

S.; Meini, Stefania; Nannicini, Rossano; Pasqui, Franco; Tramontana, Manuela; Triolo, Antonio; Maggi, Carlo Alberto published the artcile< Modulation on C- and N-Terminal Moieties of a Series of Potent and Selective Linear Tachykinin NK2 Receptor Antagonists>, Name: 4-Chloro-2-methoxybenzaldehyde, the main research area is tachykinin NK2 receptor antagonist preparation structure activity.

Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the C- and N-terminal moieties of ibodutant (MEN 15596, 1). The N-terminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C-terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity for the human NK2 receptor and high in vitro antagonist potency, indicating that a wide range of substituents at both termini can be incorporated in the mol. without detrimental effects on the interactions with the NK2 receptor. Selected compounds were tested in vivo confirming their activity as NK2 antagonists. In particular, after both iv and id administration to guinea pig, compound 61 b was able to antagonize NK2-induced colonic contractions with a potency and duration-of-action fully comparable to the reference compound 1 (MEN 15596, ibodutant).

Hoffmann, Maxi; Iacob, Ciprian; Kaysan, Gina; Simmler, Mira; Nirschl, Hermann; Guthausen, Gisela; Wilhelm, Manfred published the artcile< Charge Transport and Glassy Dynamics in Blends Based on 1-Butyl-3-vinylbenzylimidazolium Bis(trifluoromethanesulfonyl)imide Ionic Liquid and the Corresponding Polymer>, Recommanded Product: 1-(Chloromethyl)-4-vinylbenzene, the main research area is butyl vinylbenzylimidazolium bistrifluoromethanesulfonyl imide ionic liquid polymer glassy dynamic; PFG-NMR; broadband dielectric spectroscopy; charge transport; imidazolium; ionic liquid blends; ionic liquids; rheology.

Charge transport, diffusion properties, and glassy dynamics of blends of imidazolium-based ionic liquid (IL) and the corresponding polymer (polyIL) were examined by Pulsed-Field-Gradient NMR (PFG-NMR) and rheol. coupled with broadband dielec. spectroscopy (rheo-BDS). We found that the mech. storage modulus (G’) increases with an increasing amount of polyIL and G’ is a factor of 10,000 higher for the polyIL compared to the monomer (GIL’ = 7.5 Pa at 100 rad s-1 and 298 K). Furthermore, the ionic conductivity (σ0) of the IL is a factor 1000 higher than its value for the polymerized monomer with 3.4×10-4 S cm-1 at 298 K. Addnl., we found the Haven Ratio (HR) obtained through PFG-NMR and BDS measurements to be constant around a value of 1.4 for the IL and blends with 30 weight% and 70 weight% polyIL. These results show that blending of the components does not have a strong impact on the charge transport compared to the charge transport in the pure IL at room temperature, but blending results in substantial modifications of the mech. properties. Furthermore, it is highlighted that the increase in σ0 might be attributed to the addition of a more mobile phase, which also possibly reduces ion-ion correlations in the polyIL.

Tao, Zhihua; Li, Yuanxun; Peng, Yi Xiao; Su, Hua; Han, Likun; Liu, Guanting published the artcile< Electrochemical studies of prothioconazole as a novel corrosion inhibitor for copper in acidic solutions>, Application In Synthesis of 611-19-8, the main research area is prothioconazole copper corrosion current density electrochem impedance.

Prothioconazole is a fungicide that has a wide number of applications in agriculture, and it can ensure the safety of crops, users, and the environment. Prothioconazole, as a suppressor of copper dissolution in 0.5 M H2SO4 solution, has been evaluated using electrochem. experiments, weight loss tests, quantum chem. calculations, and SEM (SEM). The electrochem. test results showed that prothioconazole was an excellent inhibitor, and the anticorrosion ability increased with the inhibitor concentration The interaction of prothioconazole with copper is a spontaneous adsorption process accompanied by typical chemisorption. The number of water mols. (X) displaced by one prothioconazole mol. was obtained using diverse substitutional adsorption models based on electrochem. impedance spectroscopy (EIS) data. In addition, the Fukui functions indicate that the triazole and benzene rings and the -C=S atoms were the main active sites for the adsorption process.

Catalysts based on (R, R)-1,2-diphenylethylenediamine are, as chiral organic catalysts, applied to the asym. Michael addition to α, β-unsaturated nitroalkenes under neutral conditions. The role of an aqueous medium for organic catalytic activity can be reversed concerning hydrophilic-hydrophobic function depending on the reaction conditions. In this study, to provide an environmentally friendly system, the thiourea-based catalyst substituted with 3,5-(CF3)2-Ph was used in water solvents. The hydrophobic effect of the substituent provided fast reaction, high chem. yield, and mirror-image selectivity. This reaction allowed the preparation of GABAB agonists in an optically pure manner. Addnl., GABA (γ-aminobutyric acid) analogs such as baclofen and phenibut were synthesized as R-type S-type with high optical purity.
