Original Research


A novel series of substituted thiazole ortho-hydroxychalcones was synthesized to be physico-chemically characterized and evaluated for the anticancer activity. The chalcones were synthesized with 28–68% yields, via Claisen–Schmidt condensation in an ethanolic solution. All the synthesized compounds were purified and characterized by MS, 1H NMR, 13C NMR, IR, and melting points. The cytotoxicity of thiazole ortho-hydroxychalcones 3a3o as well as doxorubicin was determined in a panel of 9 cancer cell lines including sensitive and drug resistant phenotypes. Compounds 3a, 3b, 3c, 3j, as well as doxorubicin displayed cytotoxic effects in all the 9 tested cancer cell lines with IC50 values below 75 µM. The best samples showed IC50 values below 10 µM against 5/9 cancer cell lines for 3a, 3h, and 3o, against 7/9 cancer cell lines for 3c and 3f, and against 8/9 cancer cell lines for 3j. Hypersensitivity of all resistant cells towards 3b, 3g, 3j, 3m, and 3o was also obtained, suggesting that these compounds are appropriate molecules that could be used to combat drug resistance of cancer cells.
