Aza-heterocyclic frameworks through intramolecular pi-system trapping of spiro-N-acyliminiums generated from isoindolinone

Spiro-acetoxylactams as key substrates were obtained straightforwardly by the tandem regioselective reduction/O-acylation of spiro-isoindolinone-imides. The latter were produced in large scale in three steps from homophthalic acid. These imides were useful to provide in one step isoindolinones bearing hydroxymethyl-amide functions, tethered at quaternary carbon centre with promising biological issues. Submitted to Bronsted (TFA neat) and Lewis acid (trimethylsilyltrifluoro-methanesulfonic (TMSOTf) 10 mol%), the spiro-acetoxylactams undergo pi-cyclization of spiro-N-acyliminiums to provide diastereoselectively with pi-aromatic original pyrrolopyrido- and pyrroloazepino-isoindoles fused or not to aromatic systems. With pi-olefins, pyrrolopyridines and pyrrolo-azepines fused to isoindoline or containing amino-acids were isolated. A reaction mechanism producing all these systems is also discussed.

Effect of acidic, neutral and alkaline conditions on product distribution and biocrude oil chemistry from hydrothermal liquefaction of microalgae

Hydrothermal liquefaction (HTL) of microalgae produces high amount of water-insoluble organic compounds, the biocrude oil. Using high-growth-rate Spirulina platensis as feedstock, product fraction distribution and biocrude oil chemistry from HTL at a temperature of 240-300 degrees C under acidic, neutral and alkaline condition were studied. Positive effects on biocrude oil yield were only found with KOH and acetic acid, and these effects were stronger under milder HTL conditions. FT-ICR MS showed that O-2 class in the biocrude was high due to higher carbohydrate in the biomass, numbers of N3O5-6 species present in the sample from acetic acid run, indicating its less decarboxylation ability. GC-MS showed more ketones and amides were formed from fatty acids in catalytic HTL, and this effect was sensitive toward reaction temperature. GPC suggested more light volatiles were in biocrude from KOH run, while analysis from NMR, FT-IR and elemental confirmed its high oil quality.

Unusual intramolecular CH center dot center dot center dot O hydrogen bonding interaction between a sterically bulky amide and uranyl oxygen

The selective separation of toxic heavy metals such as uranyl can be accomplished using ligands with stereognostic hydrogen bonding interactions to the uranyl oxo group, as proposed by Raymond and co-workers (T.S. Franczyk, K.R. Czerwinski and K.N. Raymond, J. Am. Chem. Soc., 1992, 114, 8138-8146). Recently, several ligands possessing this weak interaction have been proposed involving the hydrogen bonding of NH and OH based moieties with uranyl oxygen. We herein report the structurally and spectroscopically characterized CH center dot center dot center dot O hydrogen bonding using a sterically bulky amide based ligand. In conjunction with experiments, electronic structure calculations are carried out to understand the structure, binding and the strength of the CH center dot center dot center dot O hydrogen bonding interactions. This weak interaction is mainly due to the steric effect caused by a bulky substituent around the donor group which has direct relevance in designing novel ligands in nuclear waste management processes. Although the kinetics are very slow, the ligand is also highly selective to uranyl in the presence of other interfering ions such as lanthanides.

Structural insights of sulfonamide-based NLRP3 inflammasome inhibitors: design, synthesis, and biological characterization

NLRP3 inflammasome has recently attracted much attention as a potentially druggable target to develop potential therapeutics for inflammatory and neurodegenerative disorders. In our continuing studies, structure-activity relationship studies were conducted based on a newly identified NLRP3 inhibitor, YQ-II-128, from our laboratory to understand the structural features and improve aqueous solubility. The results revealed that steric interactions at the propoxyl and amide domain of YQ-II-128 are important for the observed inhibitory potency on the NLRP3 inflammasome. The results also identified the amide domain to incorporate polar moieties to improve solubility and potentially pharmacokinetic properties. As a result, analog 10 was identified as a selective NLRP3 inhibitor with comparable potency while significantly improved aqueous solubility. Collectively, these findings strongly encourage further optmization of 10 to develop analogs with improved pharmacokinetic properties as potential NLRP3-targted therapeutics.

Association of the Fatty Acid Amide Hydrolase C385A Polymorphism With Alcohol Use Severity and Coping Motives in Heavy-Drinking Youth

Background Reduced function of fatty acid amide hydrolase, the catabolic enzyme for the endocannabinoid anandamide, can be inherited through a functional genetic polymorphism (FAAH rs324420, C385A, P129T). The minor (A) allele has been associated with reduced FAAH enzyme activity and increased risk for substance use disorders in adults. Whether this inherited difference in endocannabinoid metabolism relates to alcohol use disorder etiology and patterns of alcohol use in youth is unknown. Methods To examine this question, heavy-drinking youth (n = 302; mean age = 19.74 +/- 1.18) were genotyped for FAAH C385A. All subjects completed a comprehensive interview assessing alcohol use patterns including the Timeline Follow-back Method, Alcohol Use Disorders Identification Test (AUDIT), and Drinking Motives Questionnaire. Analyses of Covariance (ANCOVAs) were conducted to assess differences in drinking patterns and drinking motives between genotype groups, and mediation analyses investigated whether drinking motives accounted for indirect associations of genotype with alcohol use severity. Results Youth with the FAAH minor allele (AC or AA genotype) reported significantly more drinking days (p = 0.045), significantly more frequent heavy episodic drinking (p = 0.003), and significantly higher alcohol-related problems and consumption patterns (AUDIT score p = 0.045, AUDIT-C score p = 0.02). Mediation analyses showed that the association of FAAH C385A with drinking outcomes was mediated by coping motives. Conclusions These findings extend previous studies by suggesting that reduced endocannabinoid metabolism may be related to heavier use of alcohol in youth, prior to the onset of chronic drinking problems. Furthermore, differences in negative reinforcement-related drinking could account in part for this association.

Effect of rice bran hydrolysates on physicochemical and antioxidative characteristics of fried fish cakes during repeated freeze-thaw cycles

Rice bran hydrolysates (RBH) produced from hexane defatted rice bran using subcritical alkaline water extraction followed by enzymatic hydrolysis showed high protein and total phenolic contents and showed high antioxidant activity. FTIR results confirmed that RBH consisting of protein (amide I & II), saccharide, phenolic hydroxyl group and Maillard reaction products had antioxidant activity. Adding 1 and 2% RBH significantly reduced fat content in fried fish cakes by 20.9 and 29.3%, respectively, compared to the control. Lipid oxidation was significantly reduced when RBH or BHA/BHT was used. RBH at 2% was equally as effective as 0.02% BHA/BHT. RBH-treated fried fish cakes had higher concentrations of total phenolics (63.9 mg GAE/100 g sample) and showed the highest antioxidant activity (both DPPH center dot and ABTS(center dot) radical scavenging activity). This study showed that RBH can significantly improve the quality of fried cake products as it reduced fat uptake and effectively provided antioxidative protection. Consequently, RBH, as a natural alternative to synthetic antioxidants, might be used for extending the frozen shelf life of fried surimi seafood.
