Résumé
We previously reported that the cinnamylpiperazinyl group in the side chain of the chenodeoxycholic acid showed apoptosis-inducing activity on multiple myeloma cancer cell line KMS-11. In the present study, we synthesized and tested the pro-apoptotic potency of fifteen new piperazinyl bile carboxamide derived from cholic, ursodeoxycholic, chenodeoxycholic, deoxycholic and lithocholic acids on human colon adenocarcinoma cell lines DLD-1, HCT-116, and HT-29. Cell viability was first measured using XTT assay. The most of the synthetic bile carboxamide derivatives decreased significantly cell viability in a dose-dependent manner. HCT-116 and DLD-1 cell lines were more sensitive than HT-29 to tested compounds. 9c, 9d showed the best in vitro results in term of solubility and dose-response effect on the three colon adenocarcinoma cell lines. Additionally, flow cytometric and Western-blotting analysis showed that 9c induced pro-apoptosis in DLD-1 and HCT-116 whereas 9d did not. We conclude that the benzyl group improved anti-proliferative activity and that the α-hydroxyl group was found to be more beneficial at the 7-position in steroid skeleton.
