Synthesis and cytotoxicity of 2,5-dihydroxychalcones and related compounds.
A series of 2, 5-dihydroxychalcones and related compounds were synthesized, and their cytotoxicities against tumor cell lines and human umbilical venous endothelial cells (HUVEC) evaluated. It was found that chalcones, with electron-withdrawing substituents on an A ring, exhibited significant cytotoxicities. Among the synthesized compounds, 2'-chloro-2, 5-dihydroxychalcone (9) was most potent, with an IC50 value as low as 0.31 microg/mL. This compound also exhibited a significant cytotoxic selectivity toward HUVEC.
