Synthesis of phenylalaninol-derived oxazolopyrrolidone lactams and evaluation as NMDA receptor antagonists
N-Methyl-D-aspartate (NMDA) receptor antagonists are known to rescue neuronal cell death caused by excessive activation of glutamate receptors. This phenomenon, known as excitotoxicity, is implicated in the pathogenesis ...

Synthesis of pyrazolo-enaminones, bipyrazoles and pyrazolopyrimidines and evaluation of antioxidant and antimicrobial properties
A novel pyrazolo-enaminones, bipyrazoles and bipyrazolopyridines from 1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)butane-1,3-dione and 4-methyl-2-phenyl-2H-pyrazolo[3,4-b]pyridine-3,6(3aH,7H)-dione have been synthesized ...
Photochemical, Photophysical and Electrochemical Properties of a Photoisomerizable Cyclophane and its [2]Catenates with Aromatic Crown Ethers
The photochemical, photophysical, and electrochemical behaviour of t-1,2-bis(1-benzy1-4- pyridinium)ethylene (t-DBBPE2+) (used as model compound), a cyclophane made of two t-1,2-bis(4-pyridin-ium)ethylene (BPE) units (141, ...
The Role of the miR-17-92 Cluster in Autophagy and Atherosclerosis Supports Its Link to Lysosomal Storage Diseases
Establishing the role of non-coding RNA (ncRNA), especially microRNAs (miRNAs), in the regulation of cell function constitutes a current research challenge. Two to six miRNAs can act in clusters; particularly, the miR-17-92 ...
Regioselective alkylation reaction of purines under microwave irradiation
The alkylation of purines which is generally carried out after anion formation by treatment with a base and alkyl halide is complicated and in the best cases, mixtures of N-alkylated compounds are obtained. Purine derivatives ...
Inhibition of 11β-HSD1 Ameliorates Cognition and Molecular Detrimental Changes after Chronic Mild Stress in SAMP8 Mice
Impaired glucocorticoid (GC) signaling is a significant factor in aging, stress, and neurodegenerative diseases such as Alzheimer's disease. Therefore, the study of GC-mediated stress responses to chronic moderately stressful ...
Electrophysiological and behavioral responses of the black-banded oak borer Coroebus florentinus to conspecific insect and host plant volatiles
Aspects of the chemical ecology of the black-banded oak borer, (BBOB) Coroebus florentinus (Coleoptera: Buprestidae), were studied. Odors produced by males and females were similar, both qualitatively and quantitatively. ...
<strong>Assessment of Endocrine-Disrupting Properties in Cosmetic Ingredients: Focus on UV Filters and Alternative Testing Methods</strong>
Endocrine-disrupting chemicals are substances capable of interfering with hormonal systems, potentially leading to adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife. Various ...
A Joint experimental-computational comparative study of the Pd(0)-catalysed reactions of aryl iodides and aldehydes with N, O, and S tethers
The influence of the heteroatom (nitrogen, oxygen, and sulfur) on the course of the palladium‐catalysed intramolecular reactions of aryl iodides and aldehydes having heteroatom‐containing tethers has been explored by an ...
El ácido bempedoico como activador PPARalpha: nuevas perspectivas para el tratamiento de la esteatosis hepática en un modelo experimental de rata hembra
La enfermedad del hígado graso no alcohólico cursa, en sus fases iniciales, con hipertrigliceridemia y acúmulo de lípidos en el hígado (esteatosis hepática). El ácido bempedoico es un inhibidor de la ATP:citrato liasa que ...
Cytotoxic Assessment of 3,3-Dichloro-β-Lactams Prepared through Microwave-Assisted Benzylic C-H Activation from Benzyl-Tethered Trichloroacetamides Catalyzed by RuCl2(PPh3)3
Natural and synthetic ß -lactam derivatives constitute an interesting class of compounds due to their diverse biological activity. Mostly used as antibiotics, they were also found to have antitubercular, anticancer and ...
Effects of Nutrition on Cognitive Function in Adults with or without Cognitive Impairment: A Systematic Review of Randomized Controlled Clinical Trials
New dietary approaches for the prevention of cognitive impairment are being investigated. However, evidence from dietary interventions is mainly from food and nutrient supplement interventions, with inconsistent results ...
Optimization of the spontaneous tail coiling test for fast assessment of neurotoxic effects in the zebrafish embryo using an automated workflow in KNIME®
Neuroactive chemicals are frequently detected in the environment. At sufficiently high concentrations or within mixtures, they could provoke neurotoxic effects and neurological diseases to organisms and humans. Fast ...
Type of supplemented simple sugar, not merely calorie intake, determines adverse effects on metabolism and aortic function in female rats.
High consumption of simple sugars causes adverse cardiometabolic effects. We investigated the mechanisms underlying the metabolic and vascular effects of glucose or fructose intake and determined whether these effects are ...
Radical Cyclization of Trichloroacetamides: Synthesis of Lactams
Trichloroacetamides can act as radical precursors to synthesize nitrogen-containing heterocycles in a variety of processes, mainly involving atom transfer radical cyclizations (ATRC), mediated by Cu(I) or Ru(II) catalysts, ...
Stereoselective total synthesis of the putative structure of nitraraine
After the structure originally proposed for nitraraine was shown to be incorrect by total synthesis, the alternative structure 5 was recently suggested for the alkaloid on biosynthetic grounds and by comparison with the ...
Structure, bioactivity and synthesis of natural products with hexahydropyrrolo[2,3-b]indole
Research on natural products containing hexahydropyrrolo[2,3-b]indole (HPI) has dramatically increased during the past few years. Newly discovered natural products with complex structures and important biological activities ...
Tetrasubstituted imidazolium salts as potent antiparasitic agents against African and American trypanosomiases
Imidazolium salts are privileged compounds in organic chemistry, and have valuable biological properties. Recent studies show that symmetric imidazolium salts with bulky moieties can display antiparasitic activity against ...
Amino acid-protecting groups
Synthetic organic chemistry is based on the concourse of reagents and catalysts to achieve the clean formation of new bonds and appropriate protecting groups are required to prevent the formation of undesired bonds and ...
