Eudistomin U is a β-carboline derivative. The structure of this molecule is made up of a β-carboline with an aromatic indole at the 1 position, thus also functioning as an indole. Eudistomin C is also a cytotoxic molecule, and its cytotoxicity have been shown to affect certain cancer cell line and human pathogens. A recent study suggested that this cytotoxicity may allow Eudistomin C to bind to DNA molecules. In addition to this, Eudistomin C displayed antibacterial property in Gram-Positive Bacteria. This is due to Eudistomin C damaging the bacterias cell membrane and interfering with the DNA gyrase function, which directly leads to cell death.
