Targeting quorum sensing: ferulic and sinapic acids compromise Pseudomonas aeru...

Background: Pseudomonas aeruginosa is a Gram-negative pathogenic bacterium that is frequently associated with chronic infections in immunocompromised individuals, such as those with cystic fibrosis or burns [1]. The pathogenicity and virulence of P. aeruginosa are primarily regulated by quorum sensing, with the las system playing a key role in this process. This system is essential for the formation and mainten...

Novel Edaravone Derivatives as Neuroprotective Agents for the Treatment of ALS

Background: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease (ND) with limited treatment options [1]. Although with some drawbacks, Edaravone is one of the available drugs for ALS that targets oxidative stress (OS), a key factor in the pathophysiology of this disease [1]. Objective: This work aimed to evaluate the cytotoxic effects and neuroprotective potential of a new series of Edaravone der...

Efficacy of selected phenolic acids in inhibiting the LasI/LasR and PQS quorum ...

Background: Quorum sensing (QS) is a bacterial intercellular communication mechanism mediated by extracellular signalling molecules known as autoinducers [1]. LasI/LasR and pseudomonas quinolone signalling (PQS) are fundamental components of the QS system in Pseudomonas aeruginosa. These systems perform a crucial role in the regulation of gene expression in response to cell density, coordination of bi...

Biological and Medicinal Properties of Natural Chromones and Chromanones

Emerging threats to human health require a concerted effort to search for new treatment therapies. One of the biggest challenges is finding medicines with few or no side effects. Natural products have historically contributed to major advances in the field of pharmacotherapy, as they offer special characteristics compared to conventional synthetic molecules. Interest in natural products is being revitalized, in...

Rivastigmine-Benzimidazole Hybrids as Promising Multitarget Metal-Modulating Co...

With the goal of combating the multi-faceted Alzheimer's disease (AD), a series of Rivastigmine-Benzimidazole (RIV-BIM) hybrids was recently reported by us as multitarget-directed ligands, thanks to their capacity to tackle important hallmarks of AD. In particular, they exhibited antioxidant activity, acted as cholinesterase inhibitors, and inhibited amyloid-β (Aβ) aggregation. Herein, we moved forward in this ...

From Non-Alcoholic Fatty Liver to Hepatocellular Carcinoma: A Story of (Mal)Ada...

Non-alcoholic fatty liver disease (NAFLD) is a global pandemic affecting 25% of the world's population and is a serious health and economic concern worldwide. NAFLD is mainly the result of unhealthy dietary habits combined with sedentary lifestyle, although some genetic contributions to NAFLD have been documented. NAFLD is characterized by the excessive accumulation of triglycerides (TGs) in hepatocytes and enc...

In vitro neuro- and hepatotoxic profile of new psychoactive phenethylamines

In vitro neuroprotective effects of dua-acting antiparkinsonians

Boosting caffeic acid performance as antioxidant and monoamine oxidase B/catech...

Increased oxidative stress (OS) and depletion of nigrostriatal dopamine (DA) are closely linked to the neurodegeneration observed in Parkinson’s Disease (PD). Caffeic acid (CA)-based antioxidants were developed, and their inhibitory activities towards monoamine oxidases (MAOs) and catechol O-methyltransferases (COMT) were screened. The results showed that the incorporation of an extra double bond maintained or ...

Effect of a Novel Hydroxybenzoic Acid Based Mitochondria Directed Antioxidant M...

Sperm cells are particularly vulnerable to reactive oxygen species (ROS), impairing their fertilizing ability. Our objective was to study the effect of a novel mitochondrial-directed antioxidant, AntiOxBEN2, on bovine sperm function. This antioxidant was added to the semen capacitation medium (CAP), during the swim-up process, and to the fertilization medium (FERT) during the co-incubation of matured oocytes an...
