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.

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).

Hong, Xi; Zhou, Quan; Huang, Shuang; Cui, He-Zhen; Li, Zhi-Ming; Hou, Xiu-Feng published the artcile< Transition metal catalyzed C7 and ortho-selective halogenation of 2-arylbenzo[d]oxazoles>, Application In Synthesis of 128-09-6, the main research area is halosuccinimide phenyl benzoxazole rhodium catalyst regioselective halogenation; halophenyl benzoxazole preparation; phenyl halo benzoxazole preparation.

A transition metal catalyzed chlorination, bromination and iodination of 2-arylbenzo[d]oxazole with N-halosuccinimide, in which ruthenium-catalyzed halogenation occurred on the C7-position and rhodium-catalyzed halogenation occurred on the ortho-position. The C7 halogenation was only observed for 5-methyl-2-(p-substituted)arylbenzo[d]oxazoles under rhodium catalysis. Preliminary mechanistic experiments and d. functional theory (DFT) calculations suggested that the C7-halogenation catalyzed by Ru might have a single-electron-transfer (SET) radical process, while the ortho-selective halogenation catalyzed by Rh proceeds probably through a redox-neutral SN2-type mechanism. The different selectivity of Rh catalyzed halogenation was due to the charge difference between benzo[d]oxazolyl and aryl rings. The two kinds of halogenated products were proved to be versatile by constructing aryl and alkynyl groups on the C-X site via Suzuki and Sonogashira cross-coupling reactions.

The reaction proceeds through the sequential formation of a boronium species followed by deprotonation leading to the aminoborane. This reagent is then directly used in the borylation process leading, after work-up, to various boronic acid derivatives The reaction was applied to (hetero)aryl triflates, iodides, bromides and chlorides.

Receptor-related orphan receptor γ (RORγ) has emerged as an attractive therapeutic target for the treatment of cancer and inflammatory diseases. Herein, we report our effort on the discovery, optimization, and evaluation of benzothiazole and benzimidazole derivatives as novel inverse agonists of RORγ. The representative compound 27h (designated as XY123) (I) potently inhibited the RORγ transcription activity with a half-maximal inhibitory concentration (IC50) value of 64 nM and showed excellent selectivity against other nuclear receptors. 27H also potently suppressed cell proliferation, colony formation, and the expression of androgen receptor (AR)-regulated genes in AR-pos. prostate cancer cell lines. In addition, 27h demonstrated good metabolic stability and a pharmacokinetic property with reasonable oral bioavailability (32.41%) and moderate half-life (t1/2 = 4.98 h). Significantly, oral administration of compound 27h achieved complete and long-lasting tumor regression in the 22Rv1 xenograft tumor model in mice. Compound 27h may serve as a new valuable lead compound for further development of drugs for the treatment of prostate cancer.

The enantioselective aminocatalytic α-chlorination of aldehydes is a challenging reaction because of its tendency to proceed through neutral intermediates in unselective pathways. Herein we report the rational shift to a highly selective reaction pathway involving charged intermediates using hexafluoroisopropanol as solvent. This change in mechanism has enabled us to match and improve upon the yields and enantioselectivities displayed by previous methods while using cheaper aminocatalysts and chlorinating agents, 80-95% less amount of catalyst, convenient temperatures, and shorter reaction times.
