Cannabis sativa L. (C. sativa) contains an array of plant-derived (phyto) cannabinoids and terpenes that are predominantly located in the trichome cavity of the plant. Terpenes, aromatic organic hydrocarbons characterized for their role in plant protection/pollination, are gaining attention for their potential as novel therapeutics in many areas of...

The aggregation of amyloid-β (Aβ) into oligomers and fibrillary structures is critical for the pathogenesis of Alzheimer's disease (AD). Recently, research effort has been focused on developing novel agents that can preferentially suppress Aβ oligomer mediated toxicities, for example, by directly targeting these toxic assemblies. The compound RD2 h...

Genetically encoded voltage indicators (GEVIs) allow optical recording of neuronal activities with high spatial resolution. While most existing GEVIs emit in the green range, red-shifted GEVIs are highly sought after because they would enable simultaneous stimulation and recording of neuronal activities when paired with optogenetic actuators, or tw...

Naringenin (2S)-5,7-dihydroxy-2-(4-hydroxyphenyl)-3,4-dihydro-2H-1-benzopyran-4-one is a natural flavonoid found in fruits from the citrus family. Because (2S)-naringenin is known to racemize, its bioactivity might be related to one or both enantiomers. Computational studies predicted that (2R)-naringenin may act on voltage-gated ion channels, part...

The understanding of the interaction between the membrane of neurons and amyloid-β peptides is of crucial importance to shed light on the mechanism of toxicity in Alzheimer's disease. This paper describes how supercritical angle fluorescence spectroscopy was applied to monitor in real-time the interaction between a supported lipid bilayer (SLB) and...

Previously, we designed, synthesized, and evaluated a series of quinolone-benzofuran derivatives as multitargeted anti-Alzheimer's disease (anti-AD) compounds, and we discovered that WBQ5187 possesses superior anti-AD bioactivity. In this work, we investigated the pharmacokinetics of this new molecule, as well as its therapeutic efficacy in restori...

Zinc binding to β-amyloid structure could promote amyloid-β aggregation, as well as reactive oxygen species (ROS) production, as suggested in many experimental and theoretical studies. Therefore, the introduction of multifunctional drugs capable of chelating zinc metal ion and inhibiting Aβ aggregation is a promising strategy in the development of ...

Misfolding and fibrillogenesis of amyloid-β protein (Aβ) play a key role in the onset and progression of Alzheimer's disease (AD). Screening for inhibitors against Aβ amyloidogenesis is helpful for rational designing and developing new anti-AD drugs and therapeutic strategies. Dihydromyricetin, a natural flavonoid extracted from a Chinese herb, Amp...

Many studies have focused on histidine behaviors in misfolding diseases. However, histidine behaviors on mature fibrils are still unknown. In the current study, we investigated mature fibrils with various histidine states to understand the structural properties of the histidine tautomeric effect on mature fibrils. Our results show that substituting...

Protein misfolding and its deviant self-assembly to converge into amyloid fibrils is associated with the perturbation of cellular functions and thus with debilitating neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, etc. A great deal of research has already been carried out to discover a potential amyloid inhibitor tha...
