Synthesis and biological evaluation of a series of tangeretin-derived chalcones.
2009
Abstract A series of chalcones polyoxygenated on the ring A (with pentamethoxy or 2′-hydroxy-3′,4′,5′,6′-tetramethoxy substitution patterns) was synthesized from tangeretin, a natural Citrus flavonoid. These chalcones were evaluated for their antiproliferative, activation of apoptosis, inhibition of tubulin assembly and antileishmanial activities. Comparison with the reference analogous 3′,4′,5′-trimethoxylated chalcones showed that such peroxygenated substitution patterns on the ring A were less beneficial to these activities.
