Abstract

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 (LD 50: 8.5 ± 0.5 μM). This activity was associated with Mcl-1 and PARP-1 cleavage, inhibition of NFκB signaling, and DNA fragmentation, demonstrating an apoptotic cell death signaling pathway.
