Abstract
- Two novel γ -lactone derivatives, trigoheterophines A ( 1 ) and B ( 2 ), together with four known furan derivatives ( 3 – 6 ), were isolated from the stems and leaves of Trigonostemon heterophyllus . The structures of 1 and 2 were elucidated by extensive spectroscopic methods and the known compounds were identified by comparing with the data reported in literature. Among them, trigoheterophines A ( 1 ) and B ( 2 ) represent an unusual type of γ -lactone derivatives, possessing 21 carbon atoms on the carbon skeleton, and known compouds ( 3 – 6 ) are rare furan derivatives in the plant kingdom with diverse long-chain hydrocarbyl groups as substituents at C-4. All isolated compounds were evaluated for their antiproliferative activities against five human cancer cell lines: HL-60, SMMC-7721, A-549, MCF-7 and SW480 in vitro . Compounds 1 – 6 showed significant antiproliferative effects against various human cancer cell lines with IC 50 values ranging from 0.28 to 12.06 μM. These findings suggest that the discoveries of these novel γ -lactone derivatives and furan derivatives with significant antiproliferative activities isolated from T. heterophyllus could be of great importance to the development of new anticancer agents.
