  名称：

  Synthesis of antiproliferative flavones from calycopterin, major flavonoid of Calycopteris floribunda Lamk.

  摘要：

  Eighteen new analogues of 5,3'-dihydroxy-3,6,7,8,4'-pentamethoxy-flavone, a potent natural cytotoxic and antimitotic flavone, were synthesized from calycopterin, the major flavonoid of Calycopteris floribunda Lamk., a traditional Asian medicinal plant. One of them, the 3'-amino substituted analogue, displayed almost the same activity as the reference compound. Pharmacomodulation at C-3' on the B-ring, and at C-5,6,7 and 8 on the A-ring allowed to refine structure-activity relationships within the cytotoxic flavones series. (C) 2010 Elsevier Ltd.
