Fractionation of culture extracts using RP-HPLC and LC-MS showed that samples containing Questin, monomethylsulochrin and trypacidin were toxic to the human A549 lung cell line. These compounds were purified and their structure verified using NMR in order to compare their toxicity against A549 cells[1]
