Seven N-cinnamoyltetraketides (1−7), including the new Ztoussaintine
E (2), toussaintine F (6), and toussaintine G (7), were isolated from
the methanol extract of the leaves of Toussaintia orientalis using column
chromatography and HPLC. The configurations of E-toussaintine E (1) and
toussaintines A (3) and D (5) are revised based on single-crystal X-ray diffraction
data from racemic crystals. Both the crude methanol extract and the isolated
constituents exhibit antimycobacterial activities (MIC 83.3−107.7 μM) against the
H37Rv strain of Mycobacterium tuberculosis. Compounds 1, 3, 4, and 5 are cytotoxic
(ED50 15.3−105.7 μM) against the MDA-MB-231 triple negative aggressive breast
cancer cell line.
