                                    Six new synthetic bile acid derivatives were synthesized and tested in vitro against various human cancer cells (glioblastoma multiforme (GBM), multiple myeloma (KMS-11), and colonic carcinoma (HCT-116) cell lines. The best activity was obtained with compound IIIb on multiple myeloma cells (LD50: 8.5 +/- 0.5 mu M). This activity was associated with Mcl-1 and PARP-1 cleavage, inhibition of NF kappa B signaling, and DNA fragmentation, demonstrating an apoptotic cell death signaling pathway. (C) 2008 Elsevier Ltd.
