β-Carboline-1-carboxylic acid 

β-Carboline 1-carboxylic acid is a β-carboline alkaloid with anti-inflammatory, antifibrotic, antitumor and antibacterial activities. β-Carboline 1-carboxylic acid is the cAMP phosphodiesterase (IC₅₀: 96 µM) and indoleamine 2, 3-dioxygenase (IDO) inhibitor. β-Carboline 1-carboxylic acid is cytotoxic to tumor cells. β-Carboline 1-carboxylic acid inhibits inflammation through the NF-κb/p65 pathway and can reverse epithelial-mesenchymal transition (EMT). In addition, β-Carboline 1-carboxylic acid has strong inhibitory activity against S. aureus (IC₅₀: 47.70 μg/mL) and E. coli (IC₅₀: 19.17 μg/mL)^[1][2][3][4].
