Podocarpusflavone A
Based on 1 Customer Validation
Podocarpusflavone A is a biflavonoid present in the leaves of Podocarpus henkelii, with anti-tumor, topoisomerase I inhibitory, antibacterial and antifungal activities. Podocarpusflavone A exhibits antibacterial activity against Enterococcus faecalis and Pseudomonas aeruginosa. Podocarpusflavone A shows weak activity against fungal pathogens. Podocarpusflavone A targets topoisomerase I and induces cell cycle arrest and apoptosis in MCF-7 cells. Podocarpusflavone A can be used for studies on cancer, bacterial and fungal infections.

Podocarpusflavone A (PFA) (Serial two-fold dilutions from an initial 1 mg/mL; 12-24 h) shows broad-spectrum bactericidal activity against Enterococcus faecalis and Pseudomonas aeruginosa (MIC = 60 μg/mL), with weaker activity against Staphylococcus aureus (MIC = 130 μg/mL) and Escherichia coli (MIC = 250 μg/mL)[1].
Podocarpusflavone A (Serial two-fold dilutions from an initial 1 mg/mL; 24-48 h) exhibits weak antifungal activity against Candida albicans and Aspergillus fumigatus (MIC = 250 μg/mL) and Cryptococcus neoformans (MIC = 130 μg/mL) at 24 h and 48 h incubation[1].
Podocarpusflavone A (CC50 threshold of 1000 μg/mL; MIC values as measured in antibacterial and antifungal assays) has favorable selective antimicrobial activity (SI > 15) against Enterococcus faecalis and Pseudomonas aeruginosa, with lower selectivity against other tested bacterial and fungal pathogens[1].
Podocarpusflavone A (PF) (1-40 µM; 72 h) shows potent antiproliferative activity against KB, MCF-7, DLD and HEp-2 tumor cell lines with ED50 values of 4.67 µg/mL, 15.17 µg/mL, 4.95 µg/mL and 10.87 µg/mL[2].
Podocarpusflavone A (20-40 µg/mL; 24 h) induces cell cycle arrest at sub-G1/S phase and triggers apoptosis in MCF-7 cells[2].
Podocarpusflavone A shows moderate Topoisomerase I inhibitory activity with an IC50 value of 65.98 µg/mL[2].

Solvent & Solubility
DMSO : 50 mg/mL (90.50 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.25 mg/mL (2.26 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Please enter the basic information of animal experiments:

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:
