N-nitrosoamides of 7 beta-hydroxylated bile acid conjugates, particularly of the ursodeoxycholic acid family have been synthesized. The products and synthetic intermediates were fully characterized by the results of high-resolution 1H NMR, FT-IR, FABMS and ESI-MS studies. The compounds, N-nitrosoglycoursodeoxycholic acid (NOGUDCA), N-nitrosoglycoursocholic acid (NOGUCA) and N-nitrosoglycodeoxycholic acid (NOGDCA) decomposed between pH 6 and 9 in aqueous buffer solutions, indicating a t1/2 of 5-7 h while N-nitrosotauroursodeoxycholic acid (NOTUDCA) indicated a much longer t1/2 of 15-17 h. These results suggest that the compounds are relatively stable and may enter the enterohepatic circulation. Their decomposition is similar to that of other N-nitrosamides, which generate alkylating agents and thereby act as DNA mutagens.
