Coelonin
Based on 1 Customer Validation
Coelonin is a dihydrophenanthrene with anti-inflammation activity. Coelonin inhibits LPS-induced PTEN phosphorylation. Coelonin inhibits NF-κB activation and p27Kip1 degradation by regulating the PI3K/AKT pathway negatively. Coelonin can inhibit IκBα phosphorylation and degradation and increases the expression of IκBα protein.

Coelonin (2.5 μg/mL) significantly reduces both NF-κB p65 and p105/50 phosphorylation levels[1].
Coelonin (0-5 μg/mL, 1.5 h) dose dependently reduces the increase of the phosphorylation of PTEN, AKT and IκBa induced by LPS[1].
Coelonin (10 and 20 μg/ml) mitigates particulate matter 2.5 (PM2.5)-induced inflammation by reducing the generation of inflammatory factors, including interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α)[2].
The inhibition of IL-1β, IL-6 and TNF-α expression by Coelonin is independent of PTEN, whereas the inhibition of p27Kip1 degradation results in cell-cycle arrest in the G1 phase, which is dependent on PTEN[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Result:Dose dependently reduced the increase of p65 accumulation in the nucleus induced by LPS. Dose dependently reversed LPS-induced iNOS and COX2 expression. LPS (200 ng/mL) significantly increased the phosphorylation of PTEN, AKT and inhibitor of NF-κB (IκBa), which was dose-dependently reduced by coelonin pre-treatment.
