Anti-inflammatory Effect of a Limonin Derivative In Vivo and Its Mechanisms in RAW264.7 Cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A potential new limonoid derivative, (12S,12aS)-6,6,8a,12a-tetramethyl-12-(5-(4-(piperidin-1-yl)butanoyl)furan-3-yl)decahydro-1H,3H-oxireno[2,3-d]pyrano[4',3':3,3a]isobenzofuro[5,4-f]isochromene-3,8,10(6H,9aH)-trione (I-C-1), has been screened for its anti-inflammatory activity. This study aimed to demonstrate the anti-inflammatory activities of I-C-1 and to further explore the underlying mechanisms of these activities in RAW264.7 macrophages. We verified the anti-inflammatory activity of I-C-1 in vivo by a carrageenan-induced paw edema model in rats and cotton pellet-induced granuloma in mice. Further, we found that I-C-1 significantly inhibited levels of pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α in lipopolysaccharide (LPS)-induced RAW264.7 cells. I-C-1 demonstrated strong inhibition of the NF-κB activation through repression of the IKKα and IKKβ phosphorylations, as well as a significant suppression of the phosphatidylinositol 3-kinase (PI3K)/serine-threonine kinase (Akt) pathway, an upstream of the NF-κB pathway. Additionally, we verified the inhibitory effect of I-C-1 on PI3K phosphorylation by immunofluorescence assay and compared the effects of I-C-1 with the PI3K inhibitor LY294002 in IL-1β, IL-6, and TNF-α levels. The data indicated that I-C-1 likely acts as an inhibitor of PI3K, exerting anti-inflammatory effects by inhibiting the PI3K/AKT/NF-κB signaling pathway. Based on these findings, we believe that I-C-1 has the potential to be further developed as a potential therapeutic agent for inflammatory-related diseases.
