Five selaginellin derivatives, including two new selaginellins termed selaginellins M (1) and N (2), and three previously identified compounds, selaginellin (3), selaginellin A (4), and selaginellin C (5), were isolated from the Selaginella tamariscina (Beauv.) Spring plant. In addition, four known biflavonoids, namely neocryptomerin ( 6), hinokiflavone (7), pulvinatabiflavone (8), and 7''- O-methylamentoflavone (9), were also isolated. The structures of new compounds 1 and 2 were elucidated by…

All compounds, including four enantiomers, exhibited good antifungal activities against four pathogenic fungi cell lines with MIC80 values in the range of 4–32 μg/mL.

Insulin-mimetic selaginellins from Selaginella tamariscina with protein tyrosine phosphatase 1B (PTP1B) inhibitory activity.

Three new and two known selaginellin derivatives were isolated from a methanol extract of Selaginella tamariscina and showed strong glucose uptake stimulatory effects in 3T3-L1 adipocyte cells at a concentration of 5 μM, and may have value as new lead compounds for the development of agents against type 2 diabetes.

Inhibitory Effect of Selaginellins from Selaginella tamariscina (Beauv.) Spring against Cytochrome P450 and Uridine 5′-Diphosphoglucuronosyltransferase Isoforms on Human Liver Microsomes

This study investigated the drug interaction potential of two selaginellins on ten P450 isoforms and six UGT isoforms using human liver microsomes and liquid chromatography-tandem mass spectrometry to predict possible drug interactionpotential of between selangellins and co-administered drugs.

Soluble Epoxide Hydrolase Inhibitory Activity of Selaginellin Derivatives from Selaginella tamariscina

Selaginellin derivatives 1–3 isolated from Selaginella tamariscina were evaluated for their inhibition of soluble epoxide hydrolase and it was determined that the derivatives function as non-competitive inhibitors.
