Key result
Amorfrutin A significantly reduced the expression and secretion of several inflammation mediators in TNF-α-stimulated colon cells, partly due to interaction with PPARγ.
Why the study?
Does Amorfrutin A reduce the expression and secretion of inflammation mediators in TNF-α-stimulated colon cells?
Does Amorfrutin A reduce the expression and secretion of inflammation mediators in TNF-α-stimulated colon cells?
Amorfrutins act as natural PPARγ agonists with anti-inflammatory properties in colon cells, suggesting potential utility for chronic inflammatory bowel diseases.
May support natural PPARγ agonists in IBD models; leaves open clinical translation.
Amorfrutins are isoprenoid-substituted benzoic acid derivatives, which were found in Amorpha fruticosa L. (bastard indigo) and in Glycyrrhiza foetida Desf. (licorice). Recently, amorfrutins were shown to be selective activators of the nuclear receptor PPARγ. Here, we investigated the effects and PPARγ-based mechanisms of reducing inflammation in colon cells by treatment with amorfrutins. In TNF-α-stimulated colon cells amorfrutin A (1) reduced significantly the expression and secretion of several inflammation mediators, in part due to interaction with PPARγ. These results support the hypothesis that amorfrutins may have the potential to treat inflammation disorders such as chronic inflammatory bowel diseases.

Fuhr et al. (2015) studied Inflammation. Amorfrutin A vs. 0.1% DMSO (vehicle control) was evaluated on Expression and secretion of inflammatory marker genes (COX-2, GRO-α, IL-8, MIP-3α). Amorfrutin A significantly reduced the expression and secretion of several inflammation mediators in TNF-α-stimulated colon cells, partly due to interaction with PPARγ.
