摘要：

Further investigation of the aerial parts of Alomia myriadenia revealed an halimane diterpene identified as ent-8S,12S-epoxy-7R,16-dihydroxyhalima-5(10),13-dien-15,16-olide along with the known ent-16-hydroxylabda-7,13-dien-15,16-olide, ent-12Rhydroxylabda-7,13-dien-15,16-olide, 6,7-methylenedioxycoumarin (ayapin), and kaempferol-7-methylether (rhamnocitrin). Evaluated in a panel of human cancer cell lines, the 16-hydroxylabade diterpene was the most active, showing an ED50 value of 0.3 mug/ml against Lu1 (human lung cancer) cells. Tested in vitro against Trypanosoma cruzi in infected murine blood, this compound caused lysis of 100% of the parasites at 250 mug/ml. (C) 2003 Elsevier Ltd. All rights reserved.
