New Isoprenylated Flavones and Stilbene Derivative from Artocarpus hypargyreus
Three new isoprenylated flavones, hypargyflavones A–C, cudraflavone C, brosimone I, and norartocarpin showed inhibitory effects on pancreatic lipase. Expand
Isoprenylated phenolic compounds with tyrosinase inhibition from Morus nigra
A new isoprenylated sanggenon-type flavanone, nigrasin K, together with three known analogs and five known Diels–Alder adducts were isolated from the twigs of Morus nigra and showed significant inhibitory effects on mushroom tyrosinase. Expand
Diels–Alder type adducts with potent alpha-glucosidase inhibitory activity from Morus macroura
Abstract Two new Diels–Alder type adducts, macrourins I and J (1–2), along with seven known analogues (3–9) were isolated from the stems of Morus macroura Miq. The structures of the two new compoundsExpand
2-Arylbenzofuran, flavonoid, and tyrosinase inhibitory constituents of Morus yunnanensis.
Four known flavans and two novel 2-arylbenzofuran dimers showed potent inhibitory effects on mushroom tyrosinase with IC(50) values ranging from 0.12 ± 0.02 to 1.43 μM. Expand
Diels-Alder adducts with PTP1B inhibition from Morus notabilis.
Eight Diels-Alder adducts, morbilisins A-H (1-8), a known analogue, chalcomoracin (9), together with eleven known flavonoids and 2-arylbenzofurans, were isolated from the leaves of Morus notabilis and showed inhibition against PTP1B phosphatase activity in vitro. Expand
Novel grayanane diterpenoids from Rhododendron principis
Six new grayanane diterpenoids, principinols A–F (1–6), were isolated from Rhododendron principis. Compounds 1 and 2 possess unprecedented 6,10-epoxy and 5α-OH moieties, and 1 and 3 are the first twoExpand
2-Arylbenzofuran and tyrosinase inhibitory constituents of Morus notabilis
Moracins O (6) and P (10) showed inhibitory effects on mushroom tyrosinase with IC50 values being lower than that of kojic acid. Expand
Five Pairs of Meroterpenoid Enantiomers from Rhododendron capitatum.
Compounds 1a and 1b are the first pair of meromonoterpenes incorporating an unprecedented 6/6/ 6/5/5 ring system, and 1a showed antiviral activity against herpes simplex virus type 1 (HSV-1) in vitro. Expand
New Isoprenylated Phenolic Compounds from Morus laevigata
Two new isoprenylated flavonoids, laevigasins A and B and leavigasin C, together with eight known compounds, 4–11, were isolated from the twigs of Morus Laevigata and their structures were elucidated by spectroscopic methods. Expand
Antiviral clerodane diterpenoids from Dodonaea viscosa
Seven new clerodane diterpenoids, dodovisnoids A−G (1–7), were isolated from Dodonaea viscosa. The structures of these compounds were identified by extensive spectroscopic data. The absoluteExpand
