Abstract

Using a bioassay-guided fractionation approach, the most potent anti-psoriatic components of Aster squamatus herb, Aster chinensis stalks, and Aster chinensis flowers, cultivated in Egypt, were identified and evaluated against Imiquimod (IMQ)-induced psoriasis in female BALB/c mice and compared to standard drug, mometasone. The topical application of A. chinensis stalk methanolic extract exhibited the strongest anti-psoriatic effects against IMQ-induced psoriasis model, as evidenced by improvements in psoriasis area severity index (PASI) score, histopathological analysis, and spleen index. Further fractionation of A. chinensis stalk methanolic extract using petroleum ether, methylene chloride, ethyl acetate, and n-butanol revealed that the methylene chloride fraction (MCF) was the most potent. Indeed, MCF significantly reduced the PASI score, alleviated histopathological changes, and restored spleen index. Mechanistically, MCF exerted its anti-psoriatic effects by suppressing inflammation, evidenced by decreased TLR-4 gene expression and lower levels of HMGB1 and NFκBp65 protein contents. Additionally, MCF reduced serum levels of pro-inflammatory cytokines interleukin (IL)-1β, IL-6, IL-23, and IL-17 while mitigating oxidative stress through increased superoxide dismutase (SOD) activity and reduced malondialdehyde (MDA) content. Notably, the efficacy of MCF was comparable to that of mometasone, with no significant differences observed. In parallel, the chemical profile of the MCF was analyzed using UHPLC-MS/MS techniques in negative and positive ionization full scan modes. MCF of A. chinensis stalk could be used a potential therapeutic agent for psoriasis.

期刊介绍: Inflammopharmacology is the official publication of the Gastrointestinal Section of the International Union of Basic and Clinical Pharmacology (IUPHAR) and the Hungarian Experimental and Clinical Pharmacology Society (HECPS). Inflammopharmacology publishes papers on all aspects of inflammation and its pharmacological control emphasizing comparisons of (a) different inflammatory states, and (b) the actions, therapeutic efficacy and safety of drugs employed in the treatment of inflammatory conditions. The comparative aspects of the types of inflammatory conditions include gastrointestinal disease (e.g. ulcerative colitis, Crohn''s disease), parasitic diseases, toxicological manifestations of the effects of drugs and environmental agents, arthritic conditions, and inflammatory effects of injury or aging on skeletal muscle. The journal has seven main interest areas: -Drug-Disease Interactions - Conditional Pharmacology - i.e. where the condition (disease or stress state) influences the therapeutic response and side (adverse) effects from anti-inflammatory drugs. Mechanisms of drug-disease and drug disease interactions and the role of different stress states -Rheumatology - particular emphasis on methods of measurement of clinical response effects of new agents, adverse effects from anti-rheumatic drugs -Gastroenterology - with particular emphasis on animal and human models, mechanisms of mucosal inflammation and ulceration and effects of novel and established anti-ulcer, anti-inflammatory agents, or antiparasitic agents -Neuro-Inflammation and Pain - model systems, pharmacology of new analgesic agents and mechanisms of neuro-inflammation and pain -Novel drugs, natural products and nutraceuticals - and their effects on inflammatory processes, especially where there are indications of novel modes action compared with conventional drugs e.g. NSAIDs -Muscle-immune interactions during inflammation [...]
