Polygalacin D
Based on 3 publication(s) in Google Scholar
Polygalacin D (PGD) is a bioactive compound isolated from Platycodon grandiflorum with anticancer and anti-proliferative properties. PGD suppresses the expression of the IAP family of proteins including survivin, cIAP-1 and cIAP-2 and blocks the PI3K/Akt pathway by inhibiting the phosphorylation of GSK3β, Akt and the expression of PI3K. Polygalacin D induces apoptosis

Polygalacin D (0-40 µM; 48 hours) inhibits cell proliferation with IC50s of 26.49 µM in the A549 cells and 20.52 µM in the H460 cells[1]. Polygalacin D (0-20 µM; 48 hours) increases the proportion of early and late apoptotic cells, and nuclear condensation is observed in A549 and H460 cells[1]. Polygalacin D (0-20 µM; 48 hours) may exerts its apoptotic effects by regulating the apoptotic proteins and the IAP family of proteins in A549 and H460 cells[1].

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: ≥ 2.5 mg/mL (2.07 mM); Clear solution
