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.

Synthesis of .GAMMA.-Hydroxybutenolides Applying Crossed Aldol Condensation in the Presence of a Bulky Lewis Acid and Their Anti-tumor Activity
An improved synthesis of gamma-hydroxybutenolides 1a-d was achieved via crossed aldolcondensation between aldehydes 2a-d and the protected gamma-hydroxy-beta-methylbutenolides 3 or 4 using the bulky Lewis acid, aluminumtris(2,6-diphenylphenoxide) (ATPH). Using this same methodology, the gamma-hydroxybutenolides 17a-d having various heteroaromatic rings were synthesized and their anti-tumor activities
