More studies are needed to develop new drugs for problems associated with drug resistance and unfavorable side effects. The natural flavonoid of quercetin revealed a wide range of biological activities by the modulation of various targets and signaling pathways. However, quercetin's low solubility and poor bioavailability have restricted its applicability; as a result, researchers have attempted to design and synthesize numerous novel quercetin derivatives using various methodologies in order to modify quercetin's constraints; the physico-chemical properties of quercetin's molecular scaffold make it appealing for drug development; low molecular mass and chemical groups are two of these characteristics. Therefore, the biological activities of quercetin derivatives, as well as the relationship between activity and chemical structure and their mechanism of action, were investigated. These quercetin-based molecules could be valuable in the creation and discovery of medications for a number of diseases.

Atherosclerosis (AS) is increasingly recognized as a disease influenced not only by lipid metabolism and inflammation but also by the gut microbiota and their bioactive metabolites. Isoquercitrin (ISO), a natural flavonoid with food-medicine homology, has shown promising antiatherosclerotic potential, yet its underlying mechanisms remain unclear. In this study, ISO administration significantly reduced plaque burden, improved lipid profiles, and restored gut microbial balance by enriching beneficial taxa, such as , , and .

N-methyl-d-aspartate (NMDA) receptors are validated druggable targets for the treatment of Alzheimer's and other associated neurological conditions, particularly in individuals with disabilities. Considering the excitotoxicity associated with NMDA receptors, which leads to neuronal damage, cognitive impairment, and limitations of current therapeutic regimens, better therapeutic candidates are required. One of the validated drug discovery approaches is computer-assisted drug discovery, supplemented by molecular docking, mechanics, and dynamics.

Background: Fairmaire is a medicinal insect that has been used for a long time by minority ethnic groups in Yunnan, China, due to its immunomodulatory function. However, its potential applications in cosmetics have not been reported.
Methods: experiments were used to verify whether the extracts of Fairmaire (EBR) have the effect of inhibiting TYR activity and eliminating melanin deposition.

The current investigation was designed to explore the chemical composition, antioxidant capacity, enzyme inhibitory activity, and cytotoxic potential of four different extracts (Ethyl Acetate, Ethanol, Ethanol/Water (70%) and Water) derived from the aerial parts of . In vitro, assessments were performed utilizing diverse antioxidant assays, along with evaluations of neuroprotective enzyme inhibition targeting acetylcholine and butyl choline enzymes, as well as antidiabetic activities against α-amylase and α-glucosidase and a potential candidate for a tyrosinase inhibitor. LC-ESI-QTOF-MS identification provided a total of 70 compounds in the extracted samples of , including kaempferol 3-(deoxyhexosyl-hexoside)-7-hexoside, rutin, quercetin dideoxyhexoside, caffeic acid hexoside, quinoline alkaloids, morphine derivatives, and scoulerine.

Ulcerative colitis (UC) is a severe inflammatory bowel disease marked by intestinal inflammation, compromised barrier function, and gut microbiota imbalance, with a restricted range of therapeutic options currently available. Quercetin, a flavonoid extracted from fruits and vegetables, have been shown significant anti-inflammatory and microbiota-modulating effects. However, the interactions between gut microbes and quercetin in colitis remain insufficiently elucidated.
