Lansiumamide B
Lansiumamide B is a cinnamamide alkaloid, Antifungal agent and Insecticide. Lansiumamide B is isolated from the seeds of Clausena lansium. Lansiumamide B inhibits the phosphorylation of p38 MAPK, and decreases the protein and mRNA levels of TNF-α. Lansiumamide B induces abnormal mycelial growth, cell content leakage and cell wall degradation in Rhizoctonia solani. Lansiumamide B causes the death of early 4th-instar larvae of Aedes albopictus. Lansiumamide B exhibits anticonvulsant effects in epileptic rat models. Lansiumamide B can be used in studies related to plant fungal diseases.

Biological Activity
Lansiumamide B (100 μg/mL; 3-5 days) exhibits broad-spectrum in vitro antifungal activity against phytopathogenic fungi, acting against 10 species of phytopathogenic fungi, with the strongest activity against Rhizoctonia solani (EC50 = 2.99 μg/mL) and Botrytis cinerea (EC50 = 4.31 μg/mL)[1].
Lansiumamide B (100 µg/mL) potently inhibits the in vitro growth of 10 phytopathogenic fungi, with the highest inhibition rate (91.20%) against Thanatephorus cucumeris[3].
Lansiumamide B (5 μg/mL; 12 h) alters the transcriptome of Rhizoctonia solani, significantly upregulates genes related to polysaccharide hydrolysis, and enriches pathways associated with starch, sucrose and galactose metabolism. The transcriptome results are validated by qRT-PCR[1].
Lansiumamide B (5-50 μM; 30 min) dose-dependently inhibits histamine release from A23187-stimulated RBL-2H3 cells, reducing histamine release to 71.2% of that in the control group at 50 μM, with no cytotoxicity observed at this concentration[2].
Lansiumamide B (5-50 μM; 30 min) significantly reduces TNF-α secretion in A23187-stimulated RBL-2H3 cells, reaching only 47.5% of the control level at 50 μM, but exerts no significant inhibitory effect on COX-2 protein expression at concentrations up to 50 μM[2].
Lansiumamide B (5-50 μM; 30 min) does not significantly reduce the mRNA levels of COX-2, TNF-α or IL-6 in A23187-stimulated RBL-2H3 cells even at concentrations as high as 50 μM[2].
Lansiumamide B (5-50 μM; 30 min) reduces the level of phosphorylated p38 MAPK by 41.8% in A23187-stimulated RBL-2H3 cells at the concentration of 50 μM, but does not significantly alter the phosphorylation levels of PKCθ, IκBα or p65 NFκB even at the highest concentration of 50 μM[2].

Cell Line:A23187-stimulated RBL-2H3 cells
-
Concentration:5-50 μM
-
Incubation Time:30 min pre-incubation, then 3 h stimulation
-
Result:Subtly reduced COX-2, TNF-α, and IL-6 mRNA levels compared to A23187-stimulated controls, but none of these reductions were statistically significant.
-
Cell Line:A23187-stimulated RBL-2H3 cells
-
Concentration:5-50 μM
-
Incubation Time:30 min pre-incubation, then 15 min stimulation
-
Result:Caused a slight, non-statistically significant reduction in phosphorylated PKCθ relative intensity at 5 μM.
Reduced the relative intensity of phosphorylated p38 MAPK by 41.8% compared to A23187-stimulated controls at 50 μM, but this reduction was not statistically significant.
Had virtually no effect on the phosphorylation of IκBα or p65 NFκB.
Lansiumamide B (200-800 μg/mL; sprayed on both adaxial and abaxial leaf surfaces) exhibits concentration-dependent protective and curative effects against Botrytis cinerea on strawberry leaves[1].
