Synthesis and anti-tubulin evaluation of chromone-based analogues of combretastatins
摘要:
Twenty new hybrid compounds with both combretastatin and flavone moieties were synthesized. These derivatives are classified according to the position of the trimethoxyphenyl ring at C-2 or C-3 of the chromone and presence or absence of a carbonyl as a linker between C-3 and the aryl ring. Most of these compounds were prepared from hesperidin or naringin, two natural and abundant Citrus flavonoids. Seven of these combretastatin analogues revealed anti-tubulin activity but in a medium range. (c) 2006 Elsevier Ltd. All rights reserved.

A series of 3 '-aminoflavones 5,6,7,8-tetra- or 5,7-dioxygenated on the A-ring was synthesized from tangeretin or naringin, two natural Citrus flavonoids. These flavones were evaluated for antiproliferative activity, activation of apoptosis, and inhibition of tubulin assembly. The most antiproliferative flavones exhibit a common 5-hydroxy-6,7,8-trimethoxy substitution pattern on the A-ring. (C) 2009 Elsevier Ltd. All rights reserved.
