We report the synthesis and biological activity of new semi-synthetic derivatives of naturally occurring deoxycholic acid (DCA) bearing 2-cyano-3-oxo-1-ene, 3-oxo-1(2)-ene or 3-oxo-4(5)-ene moieties in ring A and 12-oxo or 12-oxo-9(11)-ene moieties in ring C. Bioassays using murine macrophage-like cells and tumour cells show that the presence of the 9(11)-double bond associated with the increased polarity of ring A or with isoxazole ring joined to ring A, improves the ability of the compounds to inhibit cancer cell growth.
