Synthesis and cytotoxicity of new heterocyclic terpenylnaphthoquinones

Several 2-arylamino-, 2-aryloxy- and 2-arylsulfanyl-6(7)-alkyl-1,4-naphthoquinones (NQ) have been prepared and further transformed into the corresponding heterocyclic-fused naphthoquinones by palladium (II)-catalyzed oxidative cyclization. The compounds synthesized have been evaluated against neoplastic cell lines. The extension of the polycyclic system clearly decreased the cytotoxic potency of the 2-substituted terpenylnaphthoquinones.

Several heterocyclic terpenylnaphthoquinones have been prepared by palladium (II)-catalyzed oxidative cyclization of the corresponding substituted naphthoquinones and evaluated as antineoplastics.Figure optionsDownload as PowerPoint slide
