Biological activities of retinoidal γ-hydroxybutenolides in cancer cell apoptosis and differentiation
摘要:
Retinoidal gamma-hydroxybutenolides 2a-d having various lengths of conjugated double bond were prepared in three steps from the corresponding aldehyde 4. Their biological activities were then measured. Of these compounds, only compound 2c possessing a structure similar to that of retinoic acid showed differentiation- inducing activity and very strong apoptosis-inducing activity in HL-60 cells.
