We have recently reported the beneficial influence of the fungal metabolite nigerloxin, a new aldose reductase inhibitor and a lipoxygenase inhibitor on oxidative stress in streptozotocin induced diabetic rats. In the present study we have investigated the antioxidant potential of nigerloxin in vitro as compared to one of the well known natural antioxidant, curcumin. The fungal metabolite nigerloxin was found to be an effective antioxidant in different in vitro assays including the phosphomolybdenum, 2,2-diphenyl-1-picrylhydrazyl (DPPH.),2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS.+) and ferric reducing antioxidant power (FRAP) methods. The antioxidant potency of nigerloxin may be attributed to its electron donating nature. The ferric reducing potency of nigerloxin as demonstrated by FRAP assay method was even found to be superior to that of the natural antioxidant curcumin.

Treatment methods in traditional Chinese medicine (TCM) are foundational to their theoretical, methodological, formulaic, and pharmacological systems, significantly contributing to syndrome differentiation and therapy. The principle of "promoting urination to regulate bowel movements" is a common therapeutic approach in TCM. The core concept is "promoting the dispersion and drainage of water dampness, regulating urination to relieve diarrhea," yet its scientific underpinning remains unclear.

The last decennia have witnessed spectacular advances in our knowledge about the influence of the gut microbiome on the development of a wide swathe of diseases that extend beyond the digestive tract, including skin diseases like psoriasis, atopic dermatitis, acne vulgaris, rosacea, alopecia areata, and hidradenitis suppurativa. The novel concept of the gut-skin axis delves into how skin diseases and the microbiome interact through inflammatory mediators, metabolites, and the intestinal barrier. Elucidating the effects of the gut microbiome on skin health could provide new opportunities for developing innovative treatments for dermatological diseases.

Introduction: Fungal endophytes have mutualistic associations with the plant's host, communicating through genetic and metabolic processes. As a result, they gain the ability to generate therapeutically effective metabolites and their derivatives.
Methods: The current study aims to assess antioxidant potential along with the identification of robust metabolites within the crude extract of a potent endophytic fungus Xylaria ellisii isolated from leaf tissues of the Acorus calamus Linn plant.

The fungal genus Fusarium is a treasure-trove of structurally diverse secondary metabolites, contributed greatly by marine-derived strains. A new cedrane sesquiterpene, fusacedrol (1), and a new fusarin member, fusarin M (2), were isolated from F. graminearum 12Ⅱ2N that was isolated as an endophyte from the marine brown alga Sargassum sp.
