Here we report the synthesis and biological activity of new semi-synthetic derivatives of naturallyoccurring glycyrrhetinic acid bearing a 2-cyano-3-oxo-1-en moiety in the A-ring and double bonds and carbonyl groups in the C, D and E rings. Bioassays using murine macrophage-like and tumor cells show that compound 4, which differs from Soloxolone methyl by the absence of a 9(11)-double bond in the
Synthesis of methyl 2-cyano-3,12-dioxo-18β-olean-1,9(11)-dien-30-oate analogues to determine the active groups for inhibiting cell growth and inducing apoptosis in leukemia cells
Fourteen of the methyl 2-cyano-3,12-dioxo-18β-olean-1,9(11)-dien-30-oate (CDODO-Me-12, 10d) analogues with different structures of ring C were synthesized to determine the active groups for inhibiting cell growth and inducing apoptosis in human leukemia HL-60 cells. An unsaturated group in ring C was required to maintain the ability to inhibit cell growth and induce apoptosis. Compound 10e with 9(11),12-dien in ring C displayed comparable apoptosis induction ability to 10d associated with decreased levels of c-FLIP, but not Mcl-1 and XIAP. Compound 10e had decreased ability to deplete GSH compared to compound 10d. Compound 10e represents a new active compound acting through a different mechanism from that of compound 10d.
