parasitic trematode responsible for the neglected tropical disease schistosomiasis. Microwave-assisted synthesis of Heck-coupled derivatives improved activity, with the substituents choice guided by the Matsy decision tree. The most active derivative 12 showed improved potency and selectivity on larval (IC50 ≈ 2.2 μM, selectivity index (SI) ≈ 22 in comparison to HepG2 cells), juvenile (IC50 = 1.7 μM, SI

Five new labdanediterpenes (1-5) together with seven known diterpenes have been isolated from a methanol extract of the aerial parts of Aster oharai. Five new structures were determined as 7alpha-hydroperoxylabda-8(17),14-dien-13(R)-ol-4-O-acetyl-alpha-L-6-deoxyidopyranoside (1), 7alpha-hydroperoxylabda-8,14-dien-13(R)-ol-4-O-acetyl-alpha-L-6-deoxyidopyranoside (2), labda-7,14-dien-13(R)-ol-4-O-a
