By means of stable isotope precursor feeding combined with nontargeted LC-MS/MS, the generated spectra were clustered and visualized in a molecular network. This led to the identification of a new member of the meroterpenoids, termed xanthomonic acid, which is composed of an isoprenylated Para-amino benzoic acid. In vitro cytotoxicity assays demonstrated activity of xanthomonic acid against several human cancer cell lines by induction of autophagy.en10.1021/acs.jnatprod.5b01049info:eu-repo/semantics/closedAccessArticle79615321537WOS:00037875820000727232656Q1Q1
