9H-Pyrido[3,4-b]indole-1-carboxylic acid Chemical Properties, Uses, Production
Uses
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].
Biological Activity
β-Carboline-1-carboxylic acid is an alkaloid that has been found in P. quassioides and has diverse biological activities.1,2,3 It reduces LPS-induced increases in MCP-1, TNF-α, IL-6, and IL-1β levels in RAW 264.7 cells when used at a concentration of 15 μg/ml and inhibits the epithelial-to-mesenchymal transition (EMT) induced by TGF-β1 in A549 cells.2 β-Carboline-1-carboxylic acid induces cytotoxicity in CT26.WT, K562, and SGC-7901 cells (IC50s = 14.96, 22.11, and 19.7 μg/ml, respectively) but not HepG2 or A549 cells (IC50s = 36.41 and 41.51 μg/ml, respectively).1 It also inhibits cAMP phosphodiesterase with an IC50 value of 96 μM.3
