4-Propyl- and 4-phenylcoumarins from T. Anderson and their cytotoxic activity.

Two new 4-phenylcoumarins, mesulepidotins A () and B (), one new 4-propylcoumarin, mesulepidotin C (), and one known 4-phenylcoumarin () were isolated from stem barks. The structures of 4-propyl- and 4-phenylcoumarins were identified by analysing 1D and 2D NMR spectra combined with high-resolution ESIMS data. Compounds were assayed to MCF-7 and HeLa cells for their cytotoxic activity.
