Six new iridoid glucosides, patriridosides D-I (1-6), and one new iridoid, scabrol A (7), along with 12 known non-glycosidic and glycosidic iridoids (8-19), have been isolated from an ethanolic… Expand
Cochlearols A and B, polycyclic meroterpenoids from the fungus Ganoderma cochlear that have renoprotective activities.
(+)- and (-)-cochlearols A (1) and B (2), two meroterpenoids with novel polycyclic skeletons, were isolated from the fruiting bodies of the fungus Ganoderma cochlear. Their structures and… Expand
Applanatumin A, a new dimeric meroterpenoid from Ganoderma applanatum that displays potent antifibrotic activity.
Applanatumin A (1), a novel meroterpenoid dimer, was isolated from the fungus Ganoderma applanatum. Its structure and absolute configuration were assigned on the basis of spectroscopic and… Expand
(±)-Sinensilactam A, a pair of rare hybrid metabolites with Smad3 phosphorylation inhibition from Ganoderma sinensis.
(+)- and (-)-Sinensilactam A (1), novel hybrid metabolites possessing a unique 2H-pyrrolo[2,1-b][1,3]oxazin-6(7H)-one ring system, were isolated from the fruit bodies of Ganoderma sinensis. The… Expand

Hydrous manganese dioxide (HMO) synthesized by redox of potassium permanganate and hydrogen peroxide was used as an adsorbent for Pb(II) removal. The specific surface area, pore volume and BJH pore… Expand
Constituents from the edible Chinese black ants (Polyrhachis dives) showing protective effect on rat mesangial cells and anti-inflammatory activity
Accumulated data have emphasized the critical role of inflammation in the pathogenesis of diabetic nephropathy (DN). Chinese black ants (Polyrhachis dives), an edible insect, are well-known for… Expand
Applanatumols A and B, meroterpenoids with unprecedented skeletons from Ganoderma applanatum
Applanatumols A (1) and B [(±)-2], two unique meroterpenoids with a novel spiro[benzofuran-2,2′-bicyclo[3.2.2]nonane] ring system and a naturally unusual dioxacyclopenta[cd]inden motif, respectively,… Expand
Three New Iridoid Glucosides from the Roots of Patrinia scabra
To probe the chemical constituents of Patrinia scabra, we undertook the phytochemical investigation on its roots, which led to the isolation and elucidation of three new iridoid glucosides,… Expand
Isolation and identification of renoprotective substances from the mushroom Ganoderma lucidum
The fruiting bodies of Ganoderma lucidum have been used in China for the prevention of a wide range of diseases including diabetic nephropathy. Our current investigation with this mushroom led to the… Expand
Dopamine derivatives from the insect Polyrhachis dives as inhibitors of ROCK1/2 and stimulators of neural stem cell proliferation
Polyrhachis dives is consumed as an insect food in some regions of China. In this study, new dopamine derivatives, (+)-polyrhadopamine A (1a) and (-)-polyrhadopamine A (1b), (+)-polyrhadopamine B… Expand
