Anti-inflammatory efficacy, fewer adverse effects, improved selectivity, and curative action are imminent issues for patients suffering from chronic inflammation-related pathologies. Then, we performed a complete and critical review about anthelmintics, discussing the main classes and the available preclinical evidence on repurposing to treat inflammation-based conditions. Despite low bioavailability, many benzimidazoles (albendazole and mebendazole), salicylanilides (niclosamide), macrocyclic lactones (avermectins), pyrazinoisoquinolones (praziquantel), thiazolides (nitazoxanide), piperazine derivatives, and imidazothiazoles (levamisole) indicate that repositioning is a promising strategy. They may represent a lower cost and time-saving course to expand anti-inflammatory options. Although mechanisms of action are not fully elucidated and well-delineated, in general, anthelmintics disrupt mitogen-activated protein kinases, the synthesis of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8, IL-12, and IFN-γ), the migration and infiltration of leukocytes, and decrease COX-2 expression, which impacts negatively on the release of prostanoids and leukotrienes.

As one of the treatment routes of rheumatoid arthritis is based on the use of nonsteroidal anti-inflammatory drugs, the use of natural products with anti-inflammatory potential becomes relevant. Brown propolis has several biological properties, including immunomodulatory and anti-inflammatory effects. Thus, the present study evaluated the therapeutic efficacy of the crude extract of brown propolis from Araucaria sp. through experimental models of analgesia, anti-inflammatory activity, and rheumatoid arthritis. Hyperalgesia was evaluated by mechanical and thermal sensitivity. Anti-inflammatory activity was evaluated by plantar volume, cell migration and NF-kB expression in carrageenan-induced paw oedema. In collagen-induced rheumatoid arthritis, it was evaluated by mechanical and thermal nociception on the plantar surface, and mechanical nociception in the femorotibial and caudal joints, evaluation of plantar volume, radiography, weight gain and biochemical profile. The results demonstrated that the oral administration of brown propolis can modulate the course of rheumatoid arthritis, and it can inhibit pain through the modulation of mechanical sensitivity. The anti-arthritic effect of propolis may be due to its anti-inflammatory capacity, which includes inhibiting oedema formation, cell migration, and NF-kB expression, as well as preserving joint space and normalizing urea levels. This was an animal model study.

Structural changes in gut microbiome were determined by 16S rRNA sequencing. Semaglutide reduced the relative abundance of Firmicutes and augmented that of Bacteroidetes.

In our previous studies, we found that quercetin can alleviate neurological dysfunction after hypoxic-ischaemic brain injury (HIBI) in neonatal mice. As demonstrated through in vitro experiments, quercetin can inhibit the activation of the TLR4/MyD88/NF-κB signalling pathway and the inflammatory response in the microglial cell line BV2 after oxygen-glucose deprivation. However, the in-depth mechanism still needs to be further elucidated. In the present study, 7 day-old neonatal ICR mice or BV2 cells were treated with quercetin with or without the SIRT1 inhibitor EX527 via neurobehavioural, histopathological and molecular methods. In vivo experiments have shown that quercetin can significantly improve the performance of HI mice in behavioural tests, such as the Morris water maze, rotarod test and pole climbing test, and reduce HI insult-induced structural brain damage, cell apoptosis and hippocampal neuron loss. Quercetin also inhibited the immunofluorescence intensity of the microglial M1 marker CD16 + 32 and significantly downregulated the expression of the M1-related proteins iNOS, IL-1β and TNF-α. Moreover, quercetin increased the immunofluorescence intensity of the microglial M2 marker CD206 and significantly increased the expression of the M2-related proteins Arg-1 and IL-10. In addition, quercetin limits the nucleocytoplasmic translocation and release of microglial HMGB1 and further suppresses the activation of the downstream TLR4/MyD88/NF-κB signalling pathway. The above effects of quercetin are partially weakened by pretreatment with EX527. Similar results were found in in vitro experiments, and the mechanism further revealed that the rebalancing effect of quercetin on microglial polarization is achieved through the SIRT1-mediated reduction in HMGB1 acetylation levels.

A thorough literature search utilizing the keywords \"luteolin\" \"Signalling Pathway\" \"cancer\" and nanoparticles was performed in the databases of Google Scholar, Web of Science, SCOPUS, UGC care list and PubMed. Through the compilation of existing research, we have discovered that luteolin possesses several therapeutic actions against various cancer via a signaling pathway involving the of NF-κB regulation, AMPK/mTOR, toll-like receptor, Nrf-2, PI3K/Akt MAPK and Wnt/β-catenin and their underlying mechanism of action has been well understood. This review intended to completely integrate crucial information on natural sources, biosynthesis, pharmacokinetics, signaling pathways, chemoprotective and therapeutic properties against various cancers, and nanoformulation of luteolin.</p>","PeriodicalId":13551,"journal":{"name":"Inflammopharmacology","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142619624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
