Bruceoside B
Bruceoside B is a PI3K/Akt/NF-κB inhibitor. Bruceoside B reduces LPS (HY-D1056)-induced nitric oxide release and the secretion of TNF-α, IL-6 and IL-1β, and decreases the activation level of apoptosis. Bruceoside B inhibits the replication, coat protein accumulation and local lesion formation of tobacco mosaic virus (TMV), and enhances the anti-infection ability of plants. Bruceoside B can be used in studies related to acute lung injury and tobacco mosaic virus infection.

Biological Activity
Bruceoside B (24 h) inhibits LPS-induced NO release in MH-S cells, with an IC50 of 45.56 μM[1].
Bruceoside B (10-40 μM; 24 h) dose-dependently inhibits LPS-induced secretion of TNF-α, IL-6, and IL-1β in MH-S cells[1].
Bruceoside B (10-40 μM) regulates the expression of NF-κB pathway and apoptosis-related proteins in LPS-stimulated MH-S cells, reduces the ratios of p-IκB-α/IκB-α and Bax/Bcl-2, downregulates p-NF-κB (with no change in NF-κB expression), and decreases the expression level of full-length Caspase-3 relative to β-actin[1].
Bruceoside B (20 μM; 48 h) inhibits the accumulation of TMV coat protein in leaf discs of Nicotiana tabacum cv. K326, indicating that it suppresses viral replication[2].
Bruceoside B (1.25-20 μM; 3-4 days) inhibits the formation of TMV local lesions in Nicotiana glutinosa leaf tissues, with an IC50 of 4.64 μM, and exhibits dose-dependent anti-TMV activity[2].

Cell Line:murine alveolar macrophage MH-S cells
-
Concentration:10, 20 and 40 μM
-
Incubation Time:24 h
-
Result:Significantly suppressed LPS-induced secretion of TNF-α, IL-6, and IL-1β in a dose-dependent manner, with statistically significant inhibition observed at all tested concentrations compared to the LPS-only group.

Animal Model:BALB/c (male, 6-8 weeks old, average weight 20 g)[1]
-
Dosage:1 mg/kg; 2 mg/kg; 4 mg/kg
-
Administration:i.p.; single dose
-
Result:Significantly improved LPS-induced lung tissue damage at all tested doses, with the 4 mg/kg dose showing the most pronounced effect: alveolar collapse, consolidation, compression, and inflammatory cell infiltration were significantly reduced compared to the LPS-only model group.
Dose-dependently blocked LPS-induced phosphorylation of PI3K and Akt in lung tissue, with significant reductions in p-PI3K/PI3K and p-Akt/Akt ratios observed at all doses.
Detected trace levels of brusatol in mouse plasma, indicating bruceoside B is catabolized to brusatol in vivo.
