Pityrogramma triangularis

SL 0101-1 (SL0101), a kaempferol glycoside, isolated from the tropical plant F. refracta, is a cell-permeable, selective, reversible, ATP-competitive p90 Ribosomal S6 Kinase (RSK) inhibitor, with an IC₅₀ of 89 nM. SL 0101-1 (SL0101) is a selective RSK1/2 inhibitor, with a K_i of 1 μM.

(8R,12R,13R)-8,12-Epoxylabd-14-en-13-ol is a diterpene found in Abies georgei. (8R,12R,13R)-8,12-Epoxylabd-14-en-13-ol is a nuclear factor kappa B (NF-κB) inhibitor that inhibits TNFα-triggered NF-κB activity (IC₅₀ = 8.7 μg/mL). (8R,12R,13R)-8,12-Epoxylabd-14-en-13-ol exhibits anti-inflammatory activity and can inhibit NO production. (8R,12R,13R)-8,12-Epoxylabd-14-en-13-ol shows significant cytotoxicity against tumor cells.

16-Nor-7,15-dioxodehydroabieticacid is a natural diterpene.

Abiesadine I is a diterpenoid inhibitor targeting LPS-induced NO production (IC₅₀>100 μg/mL) that can be isolated from Abies georgei. Abiesadine I inhibits LPS-induced nitric oxide (NO) production in RAW264.7 macrophages, exhibiting anti-inflammatory activity.

Abiesadine F is a diterpenoid isolated from Abies georgei Orr.

Abiesadine Q (compound 17) is a diterpene compound that can be isolated from the aboveground parts of Abies georgei Orr.
