Furoquinoline alkaloids of Ertela (Monnieria) trifolia (L.) Kuntze from the Suriname rainforest

Abstract 7-(2’-Hydroxy-3’-chloroprenyloxy)-4,8-dimethoxyfuroquinoline ( 1 ) and 6-(2’-hydroxy-3’-chloroprenyloxy)-4,7-dimethoxyfuroquinoline ( 2 ), together with ten known compounds, have been isolated from the aerial parts of Ertela ( Monnieria ) trifolia (L.) Kuntze. All the isolates were tested for antiproliferative activity against the A2780 human ovarian cancer cell line.
