Synthesis and antitumor activity of some analogues of flavone acetic acid.
Some coumarin-, flavonol- and flavanon-acetic acids are described. The cytotoxicity of the synthesized compounds was determined on a human colon carcinoma cell line (LoVo) through evaluation of neutral red uptake, performed by the Riddel method. All tested derivatives were able to induce a statistically significant reduction of lysosomal neutral red uptake at 5 x 10(-5) M concentration. Some compounds were more active than the reference compound flavon-8-acetic acid.
