Liriodendron tulipifera L.

N-Phenethylbenzamide is an active compound. N-Phenethylbenzamide can be extracted from Liriodendron tulipifera. N-Phenethylbenzamide can be used for the research of inflammatory diseases.

Dehydroglaucine is a potent antimicrobial alkaloid.

Oxoglaucine (O-Methylatheroline) is a natural product with multiple activities including autophagy activation, anti-inflammation, antibacterial activity, and immunoregulation. Oxoglaucine inhibits the TRPV5/calmodulin/CAMK-II pathway, suppresses TGFβ-induced Smad2 phosphorylation by upregulating Smad7, blocks Ca²⁺ influx, activates autophagy, alleviates apoptosis and inflammation, inhibits ROS production and the expression of fibrosis markers in hepatocytes, and regulates immune cell populations and responses. Oxoglaucine protects against infections caused by Candida albicans and Klebsiella pneumoniae, and exerts effects on adjuvant-induced arthritis. Oxoglaucine can be used in studies related to arthritis, liver fibrosis, bacterial infections, and fungal infections.

N-Acetylnornuciferine is an aporphine alkaloid, whose family members possess potential antibacterial, antiviral, antioxidant, or anticancer activities. N-Acetylnornuciferine can be extracted from the dried roots of Liriodendron tulipifera (American tulip tree, a plant of the Magnoliaceae family) using ethanol.
