| Targets |
The primary target of 3,7-DMF is the TGF-beta1 signaling pathway in hepatic stellate cells (HSCs). It acts as an inhibitor of TGF-beta1-induced HSC activation, a key event in the pathogenesis of liver fibrosis. By blocking this pathway, it prevents the transdifferentiation of HSCs into fibrogenic myofibroblasts.
|
|---|---|
| ln Vitro |
In vitro, 3,7-DMF effectively inhibits the activation of hepatic stellate cells induced by the pro-fibrotic cytokine TGF-beta1. It upregulates the expression of antioxidant genes and reduces the levels of reactive oxygen species (ROS), creating a cellular environment that suppresses the fibrotic response.
|
| ln Vivo |
In vivo, 3,7-DMF is an orally active compound that can be utilized to study liver fibrosis. By inducing antioxidant genes and quenching ROS, it reduces oxidative stress and inhibits the TGF-beta1-driven activation of HSCs. Its oral bioavailability makes it a practical tool for intervention studies in animal models of chronic liver disease.
|
| Enzyme Assay |
Cell-free assays for 3,7-DMF focus on its antioxidant capacity. The compound's ability to quench ROS is measured by incubating it with a known free-radical generator (e.g., ABTS or DPPH). The reduction in the radical's characteristic absorbance at a specific wavelength (e.g., 517 nm for DPPH) is measured spectrophotometrically to determine its antioxidant potential.
|
| Cell Assay |
Cellular assays are performed using primary hepatic stellate cells (HSCs) or the immortalized human HSC line (LX-2). Cells are serum-starved and then pre-treated with 3,7-DMF for 1-2 hours, followed by stimulation with TGF-beta1 (2-5 ng/mL) for 24-48 hours. HSC activation is measured by Western blot for alpha-SMA, collagen I, and fibronectin. Intracellular ROS levels are measured using a fluorescent probe (e.g., DCFH-DA).
|
| Animal Protocol |
In vivo studies are conducted in rodent models of liver fibrosis, typically induced by chronic administration of carbon tetrachloride (CCl4) or by bile duct ligation (BDL). Mice or rats are treated with 3,7-DMF via daily oral gavage for 4-8 weeks. At study termination, liver tissues are harvested for histological analysis (Sirius Red staining), measurement of hydroxyproline content, and assessment of alpha-SMA and collagen gene expression by qPCR.
|
| ADME/Pharmacokinetics |
The pharmacokinetic (PK) properties of 3,7-DMF are favorable for research applications, as it is reported to be an orally bioavailable compound. This property is critical for its use in chronic in vivo studies, allowing for convenient and reproducible dosing in animal models of liver fibrosis.
|
| Toxicity/Toxicokinetics |
The toxicological profile of 3,7-DMF is not well-documented in publicly available literature. As a flavone derivative, it is generally considered to have low toxicity. Safety assessments are ongoing, but it is intended for research use only, and standard precautions for handling chemicals should be followed.

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
