Customer Review

Based on 1 Customer Validation

Flavone is an anti-tumor compound that targets cell cycle regulatory proteins (such as cyclin B1) and apoptosis-related factors (such as p21_waf1, PIG3). Flavone selectively induces mitochondrial-mediated apoptosis pathways in tumor cells, inhibits cyclin B1 protein expression, upregulates p21_waf1, and activates p63/p73 proteins. Flavone has immunomodulatory functions that enhance natural killer cell (NK cell) activity and lymphocyte proliferation. Flavone is used in cancer research, especially for its inhibitory potential in solid tumor models such as esophageal cancer and liver cancer.

In Vivo

Flavone (25, 50, 100 mg/kg; intraperitoneal injection; once a day; for 10 consecutive days) significantly inhibits tumor growth in mouse S180 sarcoma and H22 liver cancer xenograft models, and enhances immune organ index and NK cell activity^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Kunming mice (male and female, 18-21 g) with S180 sarcoma or H22 hepatoma xenografts^[3]
Dosage:

25, 50, 100 mg/kg
Administration:

Intraperitoneal injection, once daily for 10 days
Result:

Significantly reduced tumor weight in both models compared to the negative control.
For S180 sarcoma, tumor weights were 1.38 g (25 mg/kg), 1.07 g (50 mg/kg), and 1.25 g (100 mg/kg) vs. 2.12 g in the control, with inhibition rates of 34.91%, 50.47%, and 41.04%, respectively.
For H22 hepatoma, tumor weights were 1.47 g (25 mg/kg), 1.01 g (50 mg/kg), and 1.30 g (100 mg/kg) vs. 2.16 g in the control, with inhibition rates of 31.94%, 53.24%, and 39.81%, respectively.
The middle dose (50 mg/kg) showed the strongest effect, comparable to the positive control (cyclophosphamide, CTX).

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.
