摘要: Aminosalicylic acid conjugate of ursodeoxycholic was synthesized in above 90% yield by adding a basic solution 5-aminosalicylic into the mixed anhydride formed with and ethyl chloroformate. The poorly secreted bile deconjugated cholylglycine hydrolase Clostridium perfringens, that deconjugate naturally occurring glycine taurine conju- gates acids. However, 5-amino- salicylic not absorbed from duode- num but concentrated colon wher e it partially hydrolyzed intestinal bacteria to ursodeoxy- cholic acid. We believe this unique conjugation 5-ami- nosalicylic may facilitate transpor t both 5- aminosalicylic be useful for treatment colonic inflamma- tory bowel diseases, ulcerative colitis Crohn's dis- ease.— Batta, A.
