Synthesis and Anti-thyroid Cancer Effect of Iodo-chrysin Derivatives

A novel series of iodo-chrysin derivatives with resorcinol as raw materials were synthesized according to Baker-Venkataraman reaction and their inhibitory activities in vitro against thyroid cancer cell lines (SW-579 and TT) were evaluated by the standard methyl thiazole tetrazolium (MTT) method. Biological test results showed that these derivatives possessed stronger anti-thyroid cancer activities than 5-FU. Compound 21 showed the strongest activity against SW-579 cell lines with IC50 value of 3.4μM and compound 10 showed the strongest activity against TT cell lines with IC50 value of 6.2μM, it was better than 5-FU (59.3μΜ, 18.4μM respectively).
