Eleven new diaryl-methylenecyclopentanone Mannich hydrochlorides and related compounds were synthesized with different modification on Mannich base and α, β- unsaturated bonds. The glutathione-binding ability, glutathione-s-transferase π (GSTπ) inhibition and antitumor effect of these compounds were compared. Compounds containing both Mannich base and α-unsaturated bond have GSH binding ability, GSTπ inhibitory ...
