Serratia marcescens is a common pathogenic bacterium that can cause infections in both humans and animals. It can cause a range of diseases, from slight wound infections to life-threatening bacteraemia and pneumonia. The emergence of antimicrobial resistance has limited the treatment of the diseases caused by the bacterium to a great extent. Consequently, there is an urgent need to develop nove...

We assessed the effects of 24 flavonoid derivatives, reported as anti-inflammatory, on lysosomal enzyme secretion and arachidonic acid release in rat neutrophils. Amentoflavone, quercetagetin-7-O-glucoside, apigenin, fisetin, kaempferol, luteolin and quercetin were the most potent inhibitors of beta-glucuronidase and lysozyme release. The first compound was also able to inhibit basal release. T...

Demyelination is a characteristic hallmark of the neuro-inflammatory disease multiple sclerosis. During demyelination, macrophages phagocytose myelin and secrete inflammatory mediators that worsen the disease. Here, we investigated whether flavonoids, naturally occurring immunomodulating compounds, are able to influence myelin phagocytosis by macrophages in vitro. The flavonoids luteolin, querc...

Abstract Dementia is defined by problems associated with memory, communication, problem‐solving, and other thinking abilities that impair a person’s capacity to carry out daily activities. Alzheimer’s disease one of the them in which cognitive functions get declined. Globally, more than 44 million people are diagnosed dementia till 2021. The Pathophysiology degeneration acetylcholine neurons ce...

Increasing bacterial resistance to available antibiotics makes the discovery of novel efficacious antibacterial agents a priority. A previous report showed that listeriolysin O (LLO) is a critical virulence factor and suggested that it is a target for developing anti-virulence drugs against Listeria monocytogenes infections. In this study, we report the discovery of LLO natural compound inhibit...
