Intercalative DNA binding of the marine anticancer drug variolin B
Variolin B is a rare marine alkaloid that showed promising anti-cancer activity soon after its isolation. It acts as a cyclin-dependent kinase inhibitor, although the precise mechanism through which it exerts the cytotoxic ...
Endothelin-1 promotes vascular smooth muscle cell migration across the artery wall: a mechanism contributing to vascular remodelling and intimal hyperplasia in giant-cell arteritis
Background: Giant-cell arteritis (GCA) is an inflammatory disease of large/medium-sized arteries, frequently involving the temporal arteries (TA). Inflammation-induced vascular remodelling leads to vaso-occlusive events. ...
Clinical and Pharmacokinetic Profile of Lithium Monotherapy in Exclusive Breastfeeding. A Follow-Up Case Series
Background: Most guidelines advise that women taking lithium should not breastfeed. The variation in transfer is just one reason behind this advice. Objectives: To present clinical and pharmacokinetic data of nine mother-infant ...
Toward the Synthesis of Phormidolides
A convergent and stereoselective approach for the synthesis of marine natural product (MNP) phormidolide D (PM D) is proposed. Two main disconnections divided PM D in three molecular fragments: the macrocyclic core 4, the ...
1,2-Diaryl(3-pyridyl)ethanone Oximes. Intermolecular Hydrogen Bonding Networks Revealed by X-ray Diffraction
The synthesis of a set of 1-aryl-2-aryl(3-pyridyl)ethanones 1-5 and thecorresponding ketoximes 6-9 is reported. Structural studies of oximes 6, 7 and 9 wereperformed in solution using 1H-NMR and in the solid state by X-ray ...
Origin of the selectivity in the ring-closing metathesis step of the synthesis of (−)-callyspongiolide: Formation of fourteen-versus eight-membered rings
In previous work we reported the formal synthesis of the marine macrolide (−)-callyspongiolide through a synthetic approach in which the generation of the key macrocyclic core relies on a ruthenium-catalyzed ring-closing ...
Epigenetic alterations in hippocampus of SAMP8 senescent mice and modulation by voluntary physical exercise
The senescence-accelerated SAMP8 mouse model displays features of cognitive decline and Alzheimer's disease. With the purpose of identifying potential epigenetic markers involved in aging and neurodegeneration, here we ...
Treatment of Infantile-Onset Pompe Disease in a Rat Model with Muscle-Directed AAV Gene Therapy
<p>Objective: Pompe disease (PD) is caused by deficiency of the lysosomal enzyme acid a-glucosidase (GAA), leading to progressive glycogen accumulation and severe myopathy with progressive muscle weakness. In the Infantile-Onset ...
Exploring the influence of silicon oxide microchips shape on cellular uptake using imaging flow cytometry
Nano- and micro-carriers of therapeutic molecules offer numerous advantages for drug delivery, and the shape of these</p><p>particles plays a vital role in their biodistribution and their interaction with cells. However, ...
Intracellular Mechanical Drugs Induce Cell-Cycle Altering and Cell Death
Current advances in materials science have demonstrated that extracellular mechanical cues can define cell function and cell fate. However, a fundamental understanding of the manner in which intracellular mechanical cues ...
An experimental and computational investigation of the elusive anhydrous form of Oxyma-B
We report the crystal structure of the anhydrous form of Oxyma-B, a relevant racemization suppressor for peptide synthesis, solved by direct space methodologies with X-Ray Powder Diffraction data. The structure had remained ...
Metal-Catalyzed Hydrogen Atom Transfer (MHAT) Hydroalkylation with Electron-Deficient Alkynes
We present a novel strategy for olefin construction via the reductive coupling of electron-neutral alkenes with electron-deficient alkynes under metal-catalyzed hydrogen atom transfer conditions. This methodology provides ...
Protective Role of a Donepezil-Huprine Hybrid against the β-Amyloid (1-42) Effect on Human Erythrocytes
Aβ(1-42) peptide is a neurotoxic agent strongly associated with the etiology of Alzheimer's disease (AD). Current treatments are still of very low effectiveness, and deaths from AD are increasing worldwide. Huprine-derived ...
YAT2150 is irresistible in <em>Plasmodium falciparum</em> and active against <em>Plasmodium vivax</em> and <em>Leishmania </em>clinical isolates
We recently characterized the potent antiplasmodial activity of the aggregated protein dye YAT2150, whose presumed mode of action is the inhibition of protein aggregation in the malaria parasite. Using single-dose and ...
Increasing polarity in tacrine and huprine derivatives: Potent anticholinesterase agents for the treatment of myasthenia gravis
Symptomatic treatment of myasthenia gravis is based on the use of peripherally-acting acetylcholinesterase (AChE) inhibitors that, in some cases, must be discontinued due to the occurrence of a number of side-effects. Thus, ...
Exploring Partners for the Domino α‐Arylation/Michael Addition Reaction Leading to Tetrahydroisoquinolines
Sulfonates, sulfonamides, and phosphonates have proven useful nucleophiles for palladium‐catalyzed intramolecular α‐arylation reactions leading to tetrahydroisoquinolines. Although the sulfonate α‐arylation reaction can ...
Exosomes-Based Nanomedicine for Neurodegenerative Diseases: Current Insights and Future Challenges
Neurodegenerative diseases constitute a group of pathologies whose etiology remains unknown in many cases, and there are no treatments that stop the progression of such diseases. Moreover, the existence of the blood-brain ...
AAV-mediated expression of secreted and transmembrane αKlotho isoforms rescues relevant aging hallmarks in senescent SAMP8 mice
Senescence represents a stage in life associated with elevated incidence of morbidity and increased risk of mortality due to the accumulation of molecular alterations and tissue dysfunction, promoting a decrease in the ...
