Based on 1 Customer Validation

Diplacone is an orally active geranyl flavanone. It is isolated from the fruits of Paulownia tomentosa. Diplacone reduces COX-2 levels and increases the pro-MMP2/MMP2 ratio. It induces ferroptosis-mediated cell death. Diplacone enhances mitochondrial Ca²⁺ influx and ROS production. It possesses anti-inflammatory and free radical-scavenging activities. Diplacone can be used in research related to ulcerative colitis and non-small cell lung cancer.

In Vitro

Diplacone inhibits LPS-induced inflammatory responses and reduces the expression of COX-2 in mouse macrophages^[1].
Diplacone (pre-incubated for 1 h before lipopolysaccharide stimulation at concentrations of 10-20 μM) downregulates the gene expression of LPS-induced pro-inflammatory factors TNF-α and MCP-1, and upregulates the expression of LPS-induced anti-inflammatory gene ZFP36. In macrophages differentiated from the THP-1 human monocytic leukemia cell line, it doubles the total production of TNF-α mRNA, halves the total production of MCP-1 mRNA, and slightly increases the total production of ZFP36 mRNA^[2].
Diplacone (5-40 μM; 24-48 h) potently inhibits the viability of human non-small cell lung cancer A549 cells, with an IC₅₀ value of 10.6 μM at 24 h and 7.9 μM at 48 h^[3].
Diplacone (20-40 μM; 1 min) increases the cytoplasmic Ca²⁺ concentration in non-small cell lung cancer A549 cells^[3].
Diplacone (20-40 μM; 3-24 h) induces loss of mitochondrial membrane potential in non-small cell lung cancer A549 cells^[3].
Diplacone (40 μM; 3-24 h) induces time-dependent upregulation of ATF3 protein expression in non-small cell lung cancer A549 cells^[3].

In Vivo

Diplacone (25 mg/kg; i.g.; 48 h and 24 h pre-colitis induction, then every 24 h during DSS exposure) significantly reduces colitis severity in Wistar rats, achieving a statistically significant reduction in disease activity index, 55.9% lower COX-2 levels, and a 50.7% higher pro-MMP2/MMP2 ratio compared to untreated DSS-exposed rats^[1].

Result:

Ameliorated colitis symptoms (diarrhea, rectal bleeding) and delayed symptom onset.
Showed the lowest disease activity index (DAI) on the final day of the experiment, with a statistically significant reduction compared to the DSS-only group (### p < 0.001).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
