Effusanin B Inhibits Lung Cancer by Prompting Apoptosis and Inhibiting Angiogenesis.

Cancer is one of the deadliest human diseases, causing high rates of illness and death. Lung cancer has the highest mortality rate among all malignancies worldwide. Effusanin B, a diterpenoid derived from , showed therapeutic potential in treating non-small-cell lung cancer (NSCLC).

Secotrijugins A-D, four highly oxidized and rearranged limonoids from Trichilia sinensis and their anti-inflammatory activity.

Four undescribed highly oxidized and rearranged limonoids, secotrijugins A-D, were purified from the leaves and twigs of Trichilia sinensis. Within them, secotrijugin A was characterized as a rare 30-nortrijugin-type limonoid with an unusual cleavage of 1,14-ether bond, secotrijugins B and C represented new examples with the cleavage of δ-lactone ring D, and secotrijugin D was a rare trijugin-type limonoid with an unusual 2,6-oxygen bridge. The structures of limonoids were characterized by means of spectroscopic analysis and ECD calculations.

Anti-Inflammatory -Kaurane Diterpenoids from .

Ten new -kaurane diterpenoids, including two pairs of epimers / and / and a 6,7---kauranoid , were obtained from the aerial parts of . The structures of the new compounds were confirmed by extensive spectroscopic methods and electronic circular dichroism (ECD) data analysis. An anti-inflammatory assay was applied to evaluate their nitric oxide (NO) inhibitory activities by using LPS-stimulated BV-2 cells.

Nitric oxide inhibitory iridoids as potential anti-inflammatory agents from Valeriana jatamansi.

Five new iridoids, jatadomins A-E (1-5), together with six known analogues (6-11) and one known sesquiterpenoid (12), were isolated from the roots of Valeriana jatamansi Jones. Their structures were determined by analysis of their NMR, HRESIMS, and electronic circular dichroism calculations (ECD) data. The biological evaluation revealed that compounds 1-6 had anti-inflammatory activities by inhibiting nitric oxide (NO) release in LPS-induced murine microglial BV-2 cells, with IC values of 24.
