with 5⁻36% total yields using the Aldol condensation reaction as a key reaction. Each chalcone, flavanone, flavonol, and aurone with the 3,4-dihydroxy groups in the B-ring showed high antioxidant activity. Additionally, each of the chalcones, flavanones, flavonols, and aurones with the 2,4-dihydroxy groups in the B-ring showed an excellent whitening ability.
The present invention relates to know and novel substituted aurones active as telomerase inhibitors, to their use as therapeutic agents, in particular as antitumoral agents, to a process for their preparation as to pharmaceutical compositions comprising them.
