Coumarins are important structural units in several natural products, and feature widely in biologically active compounds.Furocoumarins are potent anti-breast cancer agents, which exhibit high tumor tissue-type as well as breast cancer cell line selectivity (Figure 1), like Neo-tanshinlactone and Coumestrol.
