Peroneutone A, a new highly oxygenated diterpenoid with diverse biological activities from Peroneutypa scoparia

Discovery and Semisynthesis of Arthritacins A–J—Terpestacin-Derived Sesterterpenoids from the Plant Endophytic Fungus Arthrinium sp. HS66

Ten undescribed terpestacin-type sesterterpenoids, arthritacins A–J, together with five known analogues, together with five known analogues (11–15), were obtained from the endophytic fungus Arthrinium sp.

Smilaxsieboldiol A, a new stilbenoid from the whole plants of Smilax sieboldii Miq. (Smilacaceae).

As part of an ongoing search for new anti-adipogenic agents from medicinal plants, a new stilbenoid (6), together with eight known compounds (1-5 and 7-9), was isolated from the whole plants of Smilax sieboldii Miq. (Smilacaceae). The structure of smilaxsieboldiol A (6) was elucidated using spectroscopic and spectromet...

New Prenylated Isoindolinone Alkaloids and Polyketides from the Mangrove-Derived Fungus Aspergillus sp. SCSIO 41440

New prenylated isoindolinone alkaloids, aspernidines C-E (1–3), a new diketopiperazine alkaloid, protubonine C (4), and new polyketides, (±)-asperisocoumarin J and asperisocoumarin K (5 and 6), were isolated from the mangrove-derived fungus Aspergillus sp. SCSIO 41440, together with six known compounds (7–12). Comprehe...

Chemical constituents of Guarea glabra: a new alkaloid, a new dihydro-α-pyrone, and antitrypanosomal pimarane-type diterpenes.

Alpikwangsides A-C, three previously undescribed compounds isolated from the rhizomes of Alpinia kwangsiensis and their NO inhibitory activity.

Euphiquorins A-E, five new structurally diverse diterpenoids from Euphorbia antiquorum L.

Phytochemical investigation of the whole plant of Euphorbia antiquorum led to the isolation of sixteen diterpenoids, including five new compounds, euphiquorins A-E (1, 5-8), together with eleven known analogues (2-4, 9-16), which were elucidated by comprehensive spectroscopic analyses and quantum chemical calculations.
