Antiproliferative xanthones of Terminalia calcicola from the Madagascar rain forest

J Nat Prod. 2007 Apr;70(4):679-81. doi: 10.1021/np060627g. Epub 2007 Feb 27.

Abstract

A bioassay-guided fractionation of the EtOH extract of the Madagascan plant Terminalia calcicola led to the isolation of two new cytotoxic xanthones, termicalcicolanone A (1) and termicalcicolanone B (2). The structures of the new compounds were established on the basis of one- and two-dimensional NMR spectroscopic data. Both compounds showed modest antiproliferative activity toward the A2780 human ovarian cancer cell line.
