Abstract / Bemerkung
One new tirucallan derivative, leutcharic acid (1) was isolated from Stereospermum acuminatissimum stem bark together with the known compounds 3-oxo-22-hydroxyhopane (2), 3,4-secotirucalla-4(28),7,24-trien-3,21-dioic acid (3), 3-oxotirucalla-7,24-dien-21-oic acid (7), lupeol (4), beta-sitosterol (5) and stigmasterol (6). The structures of the isolated compounds were elucidated using 1D and 2D NMR spectroscopy in combination with literature data. To the best of our knowledge, this is the first report on the cytotoxic properties' constituents of S. acuminatissimum. Cytotoxicity of compounds 1 and 2 was assessed invitro with the WST-1 assay on human lung adenocarcinoma A549 and THP-1 human monocytic leukaemia cell lines. Both compounds showed antiproliferative activity on the cancer cells. Compound 2 was more active against THP-1 with an IC50 value of 26.83M. The sensitivity of THP-1 cells to compounds 1 and 2 indicated that these compounds might be potential leads for anticancer agent development against leukaemia.
