Divergent syntheses of spirooxindoles from oxindole-embedded four-membered synthon via cycloaddition reactions

The highly efficient construction of five and six membered heterocycle fused spirooxindoles was achieved via the [4 + 1] and formal [4 + 2] cycloaddition reactions between our rationally designed four-membered synthons and pyridinium methylides and alpha-bromoacetophenones, respectively. A wide range of richly decorated oxindole-containing chroman, chromen, and 2H-benzofuran derivatives were synthesized in moderate to high yields and diastereoselectivities.

Catalytic Pyrolysis of Guaiacol over Ni/La-Modified Hierarchical HZSM-5

Catalytic pyrolysis of guaiacol as a model compound of lignin was conducted to explore the lignin pyrolysis mechanism in this study. The effects of catalyst and temperature on product distribution were studied. Five catalysts were tested including HZSM-5, hierarchical HZSM-5, metal-modified hierarchical HZSM-5 catalysts. And the Ni/La bimetallic hierarchical HZSM-5 (NiLa/HZ-SH) contributes to the achievement of high conversion and selectivity in catalytic pyrolysis of guaiacol. we obtained the yields of monocyclic aromatic hydrocarbons over NiLa/HZ-SH (550 degrees C): Phenol (23.01%), Benzofuran (6.68%), Salicylaldehyde (1.54%), 2-Methylphenol (31.48%), 4-Methylphenol (6.54%), 2-Ethylphenol (14.89%), 4-Vinylphenol (1.45%) and Catechol (8.67%), and the maximal yields of these monocyclic aromatic hydrocarbons is 94.26%. Moreover, the yield of polycyclic aromatic hydrocarbons (PAH) as the non-target product reached a minimum of 1.46% over NiLa/HZ-SH, while it was 16.88% without catalyst. In addition, catalyst stability was investigated, the reason that led to the decrease of target products could be the acidity and surface area of catalysts decreased as the coke blocked the pore channels, spent catalyst can be successfully regenerated through calcination treatment. Finally, based on the experiment results in this work and other published studies, a guaiacol pyrolysis mechanism was summarized and proposed aiming to understand the lignin pyrolysis process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 4412-91-3. COA of Formula: C5H6O2.

Dihydrophthalazinediones accelerate amyloid beta peptide aggregation to nontoxic species

The production and accumulation of toxic amyloid plaques is one of the hallmarks of Alzheimer’s disease (AD). Amyloid beta (A beta) peptides undergo self-aggregation to form soluble oligomers, protofibrils and insoluble fibrils. This process is termed as amyloidogenesis and is a major contributor to the observed neuronal damage and memory impairment in the AD brain. Therefore, modulation of A beta aggregation process is considered to be an effective target to prevent neuronal damage under AD conditions. Modulation of amyloidogenesis involves inhibition of aggregation to form a toxic species or acceleration to drive the aggregation process to form species that are nontoxic by employing well-designed external ligands. In this context, we report a set of 2,3-dihydrophthalazine-1,4-dione (dihydrophthalazinedione, Phz) based small molecules (Phz 1-4) to modulate the A beta 42 aggregation and in cellular toxicity. Our detailed study (thioflavin T fluorescence assay, dot blot and transmission electron microscopy analysis) revealed fluorine containing Phz 4 as the potent modulator of A beta 42 aggregation by accelerating the process to form nontoxic aggregated species through hydrophobic and halogen interactions. A beta 42 aggregates formed in the presence of Phz 4 are mostly nontoxic when compared to the normal amyloid aggregates in the cellular milieu (PC12 cells). This study established that the hydrophobic and halogen interactions can be employed to develop anti-AD drug candidates. The excellent cell viability, effective modulation of A beta 42 aggregation to form nontoxic species and cellular (neuronal) rescue by Phz 4 offer a novel platform to develop therapeutic strategies for AD.

Enzymatic C-H activation of aromatic compounds through CO2 fixation

The direct C-H carboxylation of aromatic compounds is an attractive route to the corresponding carboxylic acids, but remains challenging under mild conditions. It has been proposed that the first step in anaerobic microbial degradation of recalcitrant aromatic compounds is a UbiD-mediated carboxylation. In this study, we use the UbiD enzyme ferulic acid decarboxylase (Fdc) in combination with a carboxylic acid reductase to create aromatic degradation-inspired cascade reactions, leading to efficient functionalization of styrene through CO2 fixation. We reveal that rational structure-guided laboratory evolution can expand the substrate scope of Fdc, resulting in activity on a range of mono- and bicyclic aromatic compounds through a single mutation. Selected variants demonstrated 150-fold improvement in the conversion of coumarillic acid to benzofuran + CO2 and unlocked reactivity towards naphthoic acid. Our data demonstrate that UbiD-mediated C-H activation is a versatile tool for the transformation of aryl/alkene compounds and CO2 into commodity chemicals.

Application of 591-11-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 591-11-7 is helpful to your research.

Novel structural hybrids of benzofuran-oxadiazole and benzofuran-triazole have been synthesized and evaluated for their potential against Staphylococcus aureus, Bacillus subtilis, and Escherichia coli. The excellent antibiotic activity was shown by compounds 5c and 9c against S. aureus with minimum inhibitory concentration values in 1.74-5.16 mg/mL range. The estimation of in vitro antifungal activity of synthetic compounds was performed against Trichoderma harzianum, Aspergillus niger, and Metarhizium anisopliae. Among compounds 5a-5j, only 5h and 5i showed promising antifungal potential against T. harzianum and A. niger, whereas compound 5j showed enhanced antifungal effect only against A. niger when their activity values were compared with standard drug amphotericin. No pronounced antifungal activity was shown by synthesized compounds 9a-j, except for compound 9g, which was active against all fungal strains having minimum inhibitory concentration values in 1.90-2.03 mg/mL range.
