withanolide/edema

Virginols A-C are three new withanolides containing an epoxylactol at the side chain. They were isolated from the aerial parts of Physalis virginiana Miller. Structures of these compounds were determined by analyses of their spectroscopic data, including 1D and 2D NMR. The structure of virginol A

Objectives: Withanolide A (WA), a major constituent phytochemical of the Ayurvedic herb Withania somnifera reportedly combats neurodegeneration in Alzheimer's disease and Parkinson's disease. But no study has yet reported the ability of WA in crossing the blood-brain barrier

Withanolides possess diverse biological and pharmacological activity but their immunomodulatory function is less realized. Hence, coagulin-L, a withanolide isolated from Withania coagulans Dunal has been studied for such an effect in human and murine cells, and mice model. Coagulin-L (1, 3, 10μM)

Physalin A (PA), a withanolide, was isolated from Physalis angulata L. In this study, it is shown that PA can inhibit the production of inflammatory cytokines such as PGE₂, NO, IL-1β, IL-6, and TNF-α in LPS-induced RAW 264.7 cells. Furthermore, the results indicated that PA suppressed the
