  Synthesis and in vitro cytotoxicity of a series of 3-aminoflavones

  摘要：

  To further understand the molecular requirements for the antiproliferative activity of flavonoids, a series of 3-aminoflavones and some of their derivatives were prepared and evaluated using L1210 murine leukemia. Our novel five-step synthetic approach required easily available substituted aromatic aldehydes as starting materials and proved more convenient and more general than previously reported methods. Our results in the 3-aminoflavones series indicated that the 4'-methoxy group is important for cytotoxic activity. Moreover, for the flavone-8-acetic analogs, a marked increase in potency was observed with the addition of a 3-amino or a 3-nitro group, Methoxy groups on the 6 and 7 positions of flavonoids (as in cirsiliol) also appear to be important for antiproliferative activity. These results are essential for the further understanding of the critical molecular requirements that lead to antiproliferative properties in the flavonoid series.

• The base-induced regioselective radical arylation of 3-aminochromone with aryl hydrazine

  A simple and efficient direct radical C-2 arylation of 3-aminochromone derivatives with aryl hydrazine is described. The aryl hydrazine acts as an initiator and source for the aryl radical via the cleavage of the C–N bond of aryl hydrazine. The reaction proceeds via a base-promoted single electron transfer (SET) pathway. The aryl radical abstracts a single electron from 3-aminochromone, which generates

• Regioselective 3-Nitration of Flavones: A New Synthesis of 3-Nitro- and 3-Aminoflavones
  作者：Artur Silva、Diana Patoilo、José Cavaleiro

  DOI：10.1055/s-0029-1219838

  日期：2010.6

  A new, general, and regioselective method for the 3-nitration of flavones have been developed. The nitration reaction is solvent dependent, proceeds via a nitro radical pathway, and the corresponding 3-nitroflavones have been obtained in moderate to very good yields (up to 81%). The reduction of 3-nitroflavones allowed the preparation of the corresponding 3-aminoflavones in very good yields (up to 96%).
