Sj. Cutler et al., SYNTHESIS OF FLAVONE-8-CARBOXYLIC ACID ANALOGS AS POTENTIAL ANTITUMORAGENTS, European journal of medicinal chemistry, 28(5), 1993, pp. 407-414
Furan o-aminonitriles may be utilized as precursors in the synthesis o
f flavone-8-carboxylic acids. Some results from in vivo evaluation aga
inst P388 leukemia, colon carcinoma 38, and B16 melanoma models sugges
t that selected examples of the acids are potentially as effective as
the antitumor compound, flavone acetic acid. The flavone-8-carboxylic
acids did not exhibit significant activity against an in vitro HIV scr
een or an in vitro antitumor screen consisting of a cell panel of 60 l
ines.
