Novel derivatives of deoxycholic acid bearing aliphatic or cyclic diamine moieties at the C-3 position: Synthesis and evaluation of anti-proliferative activity

Novel derivatives of deoxycholic acid bearing aliphatic or cyclic diamine moieties at the C-3 position: Synthesis and evaluation of anti-proliferative activity
A new library of deoxycholic acid derivatives bearing nitrogen-containing moieties at the C-3 position was synthesised from epoxy derivative 1 via an epoxide ring-opening reaction promoted by aliphatic or cyclic diamines and fully characterised by NMR and mass-spectroscopy. The synthesised compounds were screened for cytotoxicity against four human tumour cell lines. The results showed that some of the novel diamine-bearing derivatives displayed improved anti-proliferative activities over the parent compound DCA. Among them, a 1-methylpiperazine containing compound (6) showed promising activity and the highest selectivity against tumour cells of enterohepatic origin (HepG2: IC50 =3.6µM, SI=9.0; HuTu-80: IC50 =4.6µM, SI=6.9) and was identified as a lead molecule.
