New Sesquiterpene Lactone Dimer, Uvedafolin, Extracted from Eight Yacon Leaf Varieties (Smallanthus sonchifolius): Cytotoxicity in HeLa, HL-60, and Murine B16-F10 Melanoma Cell Lines.[Pubmed:26576855]

J Agric Food Chem. 2015 Dec 23;63(50):10856-61.

Uvedafolin, 1, a new sesquiterpene lactone dimer, was isolated from the leaves of Smallanthus sonchifolius with five related compounds, 2-6, and their cytotoxicity was assessed against three tumor cell lines (HeLa, HL-60, B16-F10 melanoma). The stereostructure of 1 was newly elucidated by ESI-TOF-MS, 1D/2D NMR, and single-crystal X-ray diffraction. Dimers 1 and 2 had the most effective IC50 values, 0.2-1.9 muM, against the three tumor cell lines when compared with monomers 3-6 (IC50 values 0.7-9.9 muM) and etoposide (IC50 values 0.8-114 muM). The ester linkages of two sets of monomers, Uvedalin, 5, and sonchifolin, 6, for 1, and enhydrin, 4, and sonchifolin, 6, for 2, as well as the acetyl group at the C-9 position, were essential for the high cytotoxicity. Dimers 1 and 2 would have potential as anticancer agents.

Trypanocidal Activity of Smallanthus sonchifolius: Identification of Active Sesquiterpene Lactones by Bioassay-Guided Fractionation.[Pubmed:23840260]

Evid Based Complement Alternat Med. 2013;2013:627898.

In order to find novel plant-derived biologically active compounds against Trypanosoma cruzi, we isolated, from the organic extract of Smallanthus sonchifolius, the sesquiterpene lactones enhydrin (1), Uvedalin (2), and polymatin B (3) by bioassay-guided fractionation technique. These compounds showed a significant trypanocidal activity against the epimastigote forms of the parasite with IC50 values of 0.84 mu M (1), 1.09 mu M (2), and 4.90 mu M (3). After a 24 h treatment with 10 mu g/mL of enhydrin or Uvedalin, parasites were not able to recover their replication rate. Compounds 1 and 2 showed IC50 values of 33.4 mu M and 25.0 mu M against T. cruzi trypomastigotes, while polymatin B was not active. When the three compounds were tested against the intracellular forms of T. cruzi, they were able to inhibit the amastigote replication with IC50 of 5.17 mu M, 3.34 mu M, and 9.02 mu M for 1, 2, and 3, respectively. The cytotoxicity of the compounds was evaluated in Vero cells obtaining CC50 values of 46.5 mu M (1), 46.8 mu M (2), and 147.3 mu M (3) and the selectivity index calculated. According to these results, enhydrin and Uvedalin might have potentials as agents against Chagas disease and could serve as lead molecules to develop new drugs.

Effect of different types of sesquiterpene lactones on the maturation of Rhinella arenarum oocytes.[Pubmed:24522008]

Zygote. 2015 Jun;23(3):406-11.

The sesquiterpene lactones (STLs) are a large class of plant secondary metabolites that are generally found in the Asteraceae family and that have high diversity with respect to chemical structure as well as biological activity. STLs have been classified into different groups, such as guaianolides, germacranolides, and melampolides etc., based on their carboxylic skeleton. In amphibians, fully grown ovarian oocytes are arrested at the beginning of meiosis I. Under the stimulus of progesterone, this meiotic arrest is released and meiosis progresses to metaphase II, a process known as oocyte maturation. The purpose of this work was to determine whether sesquiterpene lactones from the germacranolide and melampolide groups act as inhibitor agents on the meiosis of amphibian oocytes in vitro. Results for germacranolides indicated that the addition of deoxyelephantopins caused a high degree of inhibition and that minimolide showed a moderate inhibitory effect, whereas glaucolide A was inactive. Furthermore, the addition of melampolides (Uvedalin, enhydrin, polymatin A and polymatin B) showed inhibitory effects. For enhydrin and Uvedalin, inhibitory effects were observed at the higher concentrations assayed. The results of this study suggest that the inhibitory activity of the tested sesquiterpene lactones on the meiosis of Rhinella arenarum oocytes is not dependent on the group to which they belong, i.e. not on the carboxylic skeleton, but probably due to the arrangement and type of function groups present in the molecules. All assayed lactones in the germacranolide group showed low toxicity. In contrast, important differences in toxicity were observed for lactones from the melampolide group: enhydrin and Uvedalin showed low toxicity, but polymatin A and B were highly toxic.
