Abstract
Psoriasis is a chronic disease with elusive pathogenesis linked to genetic, and immune factors. Studies have shown most patients have experienced high levels of oxidative stress, which can lead to inflammation or damage. Withaferin A is a natural product with multiple pharmacological activities, including anti-tumor and anti-inflammatory effects. We investigated the effects of WA in treating Imiquimod (IMQ)-induced psoriasis mice. The epidermal pathology of mice was significantly improved after treatment. WA inhibited inflammation by decreasing the production of IL-1β, IL-6, and IFN-γ, which were induced by epidermal oxidative stress. Additionally, WA can shift the macrophage status from pro-inflammatory to anti-inflammatory.
期刊介绍:
The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
