Ipomoeassin F, a new cytotoxic macrocyclic glycoresin from the leaves of Ipomoea squamosa from the Suriname rainforest.
A new cytotoxic macrocyclic glycoresin, ipomoeassin F (6), has been isolated from the leaves of Ipomoea squamosa. The structure was elucidated by the interpretation of spectral data. Compound 6 was strongly active in the A2780 (human ovarian cancer cell line) assay with an IC(50) value of 0.036 microM.
