Mesomorphic properties improved via lateral fluorine substituent on benzoxazole-terminated mesogenic compounds

Here, laterally monofluorinated heterocyclic mesogenic compounds, 2-[4-[2-[4-alkoxy-phenyl]ethynyl]-3-fluorophenyl]-benzoxazole derivatives (nPEFPBx) with hydrogen, methyl and nitro terminal substituents (coded as nPEFPBH, nPEFPBM and nPEFPBN, respectively) at 5-position of benzoxazole unit, are synthesised and characterised. They display enantiotropic nematic mesophase with mesophase ranges of 22-30 degrees C and 32-39 degrees C on heating and cooling for nPEFPBH, 67-92 degrees C and 87-115 degrees C for nPEFPBM, 31-84 degrees C and 42-51 degrees C for nPEFPBN (n < 7), respectively, which is better than nonfluorinated and laterally difluorinated analogous. Improved mesophase property is ascribed to reduced dipole moment resulting from introduction of lateral fluorine atom in opposite direction of polar benzoxazole unit. This indicates that monofluorine substituent contributes to improve nematic mesophase for benzoxazole-terminated mesogenic compounds. In addition, the compounds nPEFPBx have high birefringence of 0.513-0.650 because of large p-conjugated mesogenic core composed of benzene, ethynyl and benzoxazole groups, which suggests a possible application in liquid crystal mixture to enhance birefringence. Meanwhile, except nPEFPBN, the compounds nPEFPBx show intense photoluminescence emission at 406-407 nm in methylene chloride solution with exciting them at absorption maxima. [GRAPHICS] .

Benzimidazole bearing Pd-PEPPSI complexes catalyzed direct C2-arylation/heteroarylation ofN-substituted benzimidazoles

A convenient and highly efficient palladium-catalyzed direct C2-arylation/heteroarylation ofN-substituted benzimidazole derivatives such asN-benzyl/3-chlorobenzyl/2,4,6-trimethylbenzyl/2,4,6-triisopropylbenzyl/aryl benzimidazoles with various aryl/heteroaryl bromides in the presence of Pd-PEPPSI (palladium-pyridine enhanced pre-catalyst preparation stabilization and initiation) complexes is reported. In order to that we have prepared a series of different symmetrical and unsymmetricalN,N ‘-diaralkyl benzimidazole-bearing Pd-PEPPSI complexes. Among all of the the prepared complexes, Pd-PEPPSI-3effectively tuned the reaction at a relatively higher rate under mild reaction conditions in an ethanol-water system. In addition, the catalytic process avoids the use of external ligand and additives. Further the reactivity was compared with commercially available copper-N-heterocyclic carbene catalyst, but the reaction was less successful. With the optimized reaction conditions, a wide range of 2-aryl/heteroaryl-N-substituted benzimidazoles were synthesized in good to excellent yields via Csp(2)-H/Csp(2)-X biaryl cross-coupling.

Alkylation of 2-Sulfanylbenzoxazole with alpha-Iodoketones in the Absence of Bases

Reaction of 2-sulfanylbenzoxazole with 1-iodopropan-2-one, 2-iodo-1-phenylethanone, and 2-iodo-1-(thiophen-2-yl)ethanone without solvent and bases afforded bis(benzoxazol-2-yl)disulfonium derivatives in a single preparative stage. The reaction proceeds as a domino-process and includes the alkylation of a sulfanyl group of benzoxazole, the reduction of iodoketone with hydrogen iodide, the oxidation of 2-sulfanylbenzoxazole to disulfide, the alkylation of disulfide atoms of sulfur, and the formation of triiodideanions. The yield of disulfonium derivatives increases twice in the presence of equimolar amount of iodine.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 421-85-2, in my other articles.

Ethynyl-Tolyl Extended 2-(2 ‘-Hydroxyphenyl)benzoxazole Dyes: Solution and Solid-state Excited-State Intramolecular Proton Transfer (ESIPT) Emitters

Dual solution/solid-state emissive fluorophores based on a 2-(2 ‘-Hydroxyphenyl)benzoxazole (HBO) core bearing one or two ethynyl-tolyl moieties at different positions were synthesized via an expedite two-step synthetic procedure. HBO derivatives are known to display intense Excited-State Intramolecular Proton Transfer (ESIPT) emission in the solid-state but are mildly emissive in solution due to the detrimental flexibility of the excited-state opening efficient non-radiative pathways. The sole introduction of a rigid ethynyl moiety led to a sizeable enhancement of the fluorescence quantum yield in solution, up to a 15-fold increase in toluene as compared to unsubstituted HBO dyes while keeping the high solid-state fluorescence efficiency. The position of the substitution on the pi-conjugated core led to subtle fine-tuning of maximum emission wavelengths and quantum yields. Moreover, we show that the ethynyl tolyl substituent at the para position of the phenol ring is a suitable moiety for an efficient stabilization of the corresponding emissive anionic HBO derivatives in dissociative solvents like DMF THF or EtOH. These observations were confirmed in CH3CN by a basic titration. For all dyes, the nature of the excited-state involved in the fluorescence emission was rationalized using ab initio calculations.

Synthesis, p38 MAP kinase inhibition, anti-inflammatory activity, and molecular docking studies of 1,2,4-triazole-based benzothiazole-2-amines

Recent studies have demonstrated that inhibition of p38 MAP kinase could effectively inhibit pro-inflammatory cytokines including TNF- and interleukins. Thus, inhibition of this enzyme can prove greatly beneficial in the therapy of chronic inflammatory diseases. A new series of N-[3-(substituted-4H-1,2,4-triazol-4-yl)]-benzo[d]thiazol-2-amines (4a-n) were synthesized and subjected to in vitro evaluation for anti-inflammatory activity (BSA anti-denaturation assay) and p38 MAPK inhibition. Among the compounds selected for in vivo screening of anti-inflammatory activity (4b, 4c, 4f, 4g, 4j, 4m, and 4n), compound 4f was found to be the most active with an in vivo anti-inflammatory efficacy of 85.31% when compared to diclofenac sodium (83.68%). It was also found to have a low ulcerogenic risk and a protective effect on lipid peroxidation. The p38 MAP kinase inhibition of this compound (IC50=0.036 +/- 0.12M) was also found to be superior to the standard SB203580 (IC50=0.043 +/- 0.27M). Furthermore, the in silico binding mode of the compound on docking against p38 MAP kinase exemplified stronger interactions than those of SB203580.

Synthesis and biological evaluation of new N-benzylpyridinium-based benzoheterocycles as potential anti-Alzheimer’s agents

A novel series of benzylpyridinium-based benzoheterocycles (benzimidazole, benzoxazole or benzothiazole) were designed as potent acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors. The title compounds 4a-q were conveniently synthesized via condensation reaction of 1,2-phenylenediamine, 2-amino-phenol or 2-aminothiophenol with pyridin-4-carbalehyde, followed by N-benzylation using various benzyl halides. The results of in vitro biological assays revealed that most of them, especially 4c and 4g, had potent anticholinesterase activity comparable or more potent than reference drug, donepezil. The kinetic study demonstrated that the representative compound 4c inhibits AChE in competitive manner. According to the ligand-enzyme docking simulation, compound 4c occupied the active site at the vicinity of catalytic triad. The compounds 4c and 4g were found to be inhibitors of A beta self-aggregation as well as AChE-induced A beta aggregation. Meanwhile, these compounds could significantly protect PC12 cells against H2O2-induced injury and showed no toxicity against HepG2 cells. As multi-targeted structures, compounds 4c and 4g could be considered as promising candidate for further lead developments to treat Alzheimer’s disease.

K313, a novel benzoxazole derivative, exhibits anti-inflammatory properties via inhibiting GSK3 activity in LPS-induced RAW264.7 macrophages

Benzoxazole and its derivatives have been widely studied in recent years due to their various biological properties. A previous study has demonstrated that K313 (1H-indole-2,3-dione 3-(1,3-benzoxazol-2-ylhydrazone)), a novel benzoxazole derivative, inhibits T cell proliferation to yield immunosuppressive effects. However, there are no related reports about its anti-inflammatory effects. In the present study, we investigated the anti-inflammatory properties and the underlying molecular mechanism of K313 in lipopolysaccharide (LPS)-induced RAW264.7 macrophages. K313 dose-dependently (5, 10, and 20M) inhibited LPS-stimulated nitric oxide (NO), interleukin (IL)-6, tumor necrosis factor (TNF)-, and 3-nitrotyrosine (3-NT) production and significantly decreased the gene transcription levels of inducible nitric oxide (iNOS), IL-6, and TNF-. In addition, the results showed that the inflammatory cytokines suppressed by K313 were not regulated by p65 NF-B, ERK1/2, AKT, or p38 MAPK. Instead, K313 increased phosphorylation of glycogen synthase kinase-3 beta (GSK-3) (Ser9) resulting in GSK-3 deactivation. Moreover, in LPS-stimulated RAW264.7 macrophages, K313 and lithium chloride (LiCl) had a synergistic effect on the anti-inflammatory response. These results indicated that K313 exhibited anti-inflammatory properties and revealed the potential mechanism. K313 can increase GSK-3 (Ser9) phosphorylation to decrease GSK-3 activation in LPS-induced RAW264.7 macrophages.
