Inhibitory effect of flavonoids on N-acetylation of 5-aminosalicylic acid in cultured rat hepatocytes.
5-Aminosalicylic acid (5-ASA) is an effective drug for the treatment of ulcerative colitis and Crohn's disease. A large group of flavonoids was investigated for their inhibitory effects on the N-acetyl-conjugation of 5-ASA in rat hepatocytes and subcellular preparations. When added to cultured hepatocytes, some flavonoids inhibited the production of N-acetyl-5-aminosalicylic acid (5-AcASA) with...

N-acetyl 5-aminosalicylic acid (5-AcASA) that was intracellularly formed from 5-aminosalicylic acid (5-ASA) at 200 microM was discharged 5.3, 7.1, and 8.1-fold higher into the apical site than into the basolateral site during 1, 2, and 4-hour incubations, respectively, in Caco-2 cells grown in Transwells. The addition of flavonols (100 microM) such as fisetin and quercetin with 5-ASA remarkably...
