概要
An organic extract prepared from Rinorea anguifera was investigated in order to identify the natural principle(s) responsible for stabilization of a topoisomerase I-DNA covalent binary complex. Bioassay-guided fractionation resulted in the isolation of mauritianin and (+)-syringaresinol as new topoisomerase I inhibitors, and also of the known inhibitor camptothecin.
