Translational Research and Drug Discovery for Neurodegeneration: Challenges for Latin America
Perhaps one of the most significant scientific challenges is to understand the human brain. Neuroscience research has had a considerable impact on individuals, families, and society. However, before we can have a real ...
Cannabidiol Modulates the Motivational and Anxiety-Like Effects of 3,4-Methylenedioxypyrovalerone (MDPV) in Mice
: 3,4-Methylenedioxypyrovalerone (MDPV) is a new psychoactive substance (NPS) and the most widespread and life-threatening synthetic cathinone of the "bath salts". Preclinical research has proven the cocaine-like psychostimulant ...
Convergent Approaches for the Synthesis of the Anti-tumoral Peptide, Kahalalide F. Study of Orthogonal Protecting Groups
Kahalalide compounds are peptides that are isolated from a Hawaiian herbivorous marine species of mollusc, Elysia rufescens, and its diet, the green alga Bryopsis sp. Kahalalide F and its synthetic analogues are the most ...
ADAM10 in Alzheimer's disease: Pharmacological modulation by natural compounds and its role as a peripheral marker
Alzheimer's disease (AD) represents a global burden in the economics of healthcare systems. Amyloid-β (Aβ) peptides are formed by amyloid-β precursor protein (AβPP) cleavage, which can be processed by two pathways. The ...
Inhibition of NMDA receptors through a membrane-to-channel path
N-methyl-D-aspartate receptors (NMDARs) are transmembrane proteins that are activated by the neurotransmitter glutamate and are found at most excitatory vertebrate synapses. NMDAR channel blockers, an antagonist class of ...
Neuroprotective Effects of the Amylin Analog, Pramlintide, on Alzheimer's Disease Are Associated with Oxidative Stress Regulation Mechanisms
Administration of the recombinant analog of the pancreatic amyloid amylin, Pramlintide, has shown therapeutic benefits in aging and Alzheimer's disease (AD) models, both on cognition and amyloid-beta (Aβ) pathology. However, ...
Synthesis of Alkaloids and Compounds Containing the 3,4-Benzomorphan Scaffold
Several natural products, bearing an embedded hexahydro-2,6-methano-1-benzazocine framework (3,4-benzomorphan) – a heterocyclic regioisomer of the 6,7-benzomorphan substructure found in morphine alkaloids, have therapeutic ...
Stereocontrolled access to enantiopure to enantiopure 7-substituted cis- and trans-octahydroindoles
Cyclocondensation of (R)-phenylglycinol with stereoisomeric mixtures (racemates, cis/trans) of 3-substituted 2- oxocyclohexaneacetates stereoselectively afforded tricyclic oxazoloindolone lactams, from which straightforward ...
Comparative assessment of the sensitivity of fish early-life stage, daphnia and algae to the chronic ecotoxicity of xenobiotics - perspectives for alternatives to animal testing
No-observed-effect concentrations (NOECs) are used in environmental hazard classification and labeling of chemicals and their environmental risk assessment. They are typically obtained using standard tests such as the fish ...
Electrochemical analysis of gold nanoparticles multifunctionalised withCytochrome c and a zinc Porphyrin
Cytochrome c (Cyt c), known for its functional redox capabilities, plays a pivotal role in biological processes such as the electron transport chain and apoptosis. However, understanding how different conjugation strategies ...
Avenços cap a la síntesi de les formidolides B i C
[cat] En el present treball es descriu la millora més important realitzada en el procés de la síntesi de les formidolides B i C. Aquesta millora es basa en un canvi d'estratègia per sintetitzar el nucli macrocíclic d'aquesta ...
Developmental neurotoxicity evaluation of three Chinese herbal medicines in zebrafish larvae by means of two behavioral assays: Touch-evoked response and light/dark transition
Chinese herbal medicine (CHM) is used among pregnant women. However, the question of its safety during pregnancy remains unclear. The use of these products relies on history of use data but there are specific toxicities ...
1,2-Dimethylindole-3-sulfonyl (MIS) as protecting group for the side chain of arginine
The protection of arginine (Arg) side chains is a crucial issue in peptide chemistry because of the propensity of the basic guanidinium group to produce side reactions. Currently, sulfonyl-type protecting groups, such as ...
Neuroadaptive changes and behavioral effects after a sensitization regime of MDPV
3,4-methylenedioxypyrovalerone (MDPV) is a synthetic cathinone with cocaine-like properties. In a previous work, we exposed adolescent mice to MDPV, finding sensitization to cocaine effects, and a higher vulnerability to ...
A New Family of Subnanomolar inhibitors of Soluble Epoxide Hydrolase The FASEB journal, 13 May 2022, 36, supplement 1
The pharmacological inhibition of soluble epoxide hydrolase (sEH) has been suggested as a potential therapy for the treatment of pain and inflammatory diseases through the stabilization of epoxyeicosatrienoic acids, ...
Curcumin as a hepatoprotective agent against chemotherapy-induced liver injury
Despite significant advances in cancer therapeutics, chemotherapy remains the cornerstone of treatment for many tumors. Importantly, however, chemotherapy-induced toxicity, including hepatotoxicity, can lead to the ...
Degradation of pheromone and plant volatile components by a same Odorant-Degrading Enzyme in the cotton leafworm, Spodoptera littoralis
Background: Odorant-Degrading Enzymes (ODEs) are supposed to be involved in the signal inactivation step within the olfactory sensilla of insects by quickly removing odorant molecules from the vicinity of the olfactory ...
A fluorogenic cyclic peptide for imaging and quantification of drug-induced apoptosis
Programmed cell death or apoptosis is a central biological process that is dysregulated in many diseases, including inflammatory conditions and cancer. The detection and quantification of apoptotic cells in vivo is hampered ...
A multicomponent reaction platform towards multimodal near-infrared BODIPY dyes for STED and fluorescence lifetime imaging
We report a platform combining multicomponent reaction synthesis and automated cell-based screening to develop biocompatible NIR-BODIPY fluorophores. From a library of over 60 fluorophores, we optimised compound NIRBD-62c ...
