Polygalacin D

Polygalacin D (PGD) is a bioactive compound isolated from Platycodon grandiflorum (Jacq.) 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.

How to use

In Vitro:

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. 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. 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.
