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[1]

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]. Cell Proliferation Assay[1] Cell Line: A549 and H460 cancer cell lines
