Our analysis also revealed correlations among epoxygenase products derived from arachidonic acid (AA), linoleic acid (LA), and α-linolenic acid (ALA) via cytochrome P450 (CYP) pathways. Furthermore, six potential oxylipins were identified, as offering insights into the mechanisms by which panaxynol may modulate diabetes.

This study aimed to investigate the effects and mechanisms of <em>Strobilanthes sarcorrhiza</em> root phenolic extract (CTS) on streptozotocin (STZ)-induced DN in mice. Firstly, the constituents in CTS were characterized by UPLC-QTOF-MS. Thirty-three constituents were identified, including 12 phenylethanoid glycosides and their derivatives, 14 phenylpropanoid glycosides derivatives, 6 polyphenols derivatives, and 1 other constituent.

Thirty-two out of thirty-three constituents showed anti-DN activity; their mechanism of action was significantly linked to tumor-, glycosylation-, metabolism-related pathways, etc. Furthermore, the effectiveness of CTS against DN and its <em>in vivo</em> mechanism was assessed by combining immunohistochemistry, untargeted metabolomics, biochemical evaluation, and histopathological examination. The findings showed that CTS improved blood glucose and lipid levels in diabetic mice, reduced serum levels of ALT, CREA, UREA, IL-1β, and IL-17, decreased pathological damage and fibrosis in kidney tissue, and lowered the protein expression of VEGF, Laminin, TNF-α, and NF-κB in kidney tissue.
