AI Article Synopsis
Article Abstract
The fungus Inonotus obliquus (Pers.) Pil. synthesised high-molecular-weight phenolic pigments that were assigned to melanins according to their physicochemical properties. It was showed that copper ions (0.008%), pyrocatechol (1.0 mM), and tyrosine (20.0 mM) stimulated the melanogenesis. The production of melanin correlated with the synthesis of o- and p-diphenoloxidases. The fungal melanin had strong antioxidant and genoprotective effects.

The objective of this study is to comprehensively to identify the core pharmacological components and their respective targets of three medicinal fungi Sanghuangs including Sanghuangporus vaninii (SV), Sanghuangporus lonicericola (SL), and Inonotus hispidus (IH). Metabolomics analysis indicated that a total of 495 and 660 differential metabolites were obtained in mycelium and fermentation broth samples among three Sanghuangs, respectively. The network pharmacology analysis showed that 6-[1]-ladderane hexanol, R-nostrenol, candidone, ellagic acid, and quercetin were the overlapping active ingredients of three Sanghuang species for diabetes mellitus, immune system disease, and neoplasm.

Objective: To explore the antitumor effect of Inonotus obliquus extract on 4T1 tumor-bearing mice in vivo and its possible mechanism.
Methods: 4T1 tumor-bearing mice model was established. After successful modeling, tumor-bearing mice were randomly divided into model control group, cyclophosphamide(CTX) positive group, and high, medium and low dose groups of Inonotus obliquus extract, with 10 mice in each group, which were administered continuously for 21 days.

Fungi have a wide range of secondary metabolites but are used much less frequently than plants in both folk and official medicine. Fungotherapy could be considered a promising trend in the development of modern natural therapy.
