Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/22828439

Calactin and calotropin were the major cardenolides in Danaus plexippus reared on A. fruticosa or A. curassavica. It was discovered, that calactin could be potential anticancer compound that was supported for human leukemia cells. It was shown, that calactin decreased the expression of cell cycle regulatory proteins Cyclin B1, Cdk1, and Cdc25C was consistent with a G2/M phase arrest. Furthermore, calactin induced extracellular signal-regulated kinase (ERK) phosphorylation, activation of caspase-3, caspase-8, and caspase-9, and PARP cleavage.
