One-pot multicomponent synthesis to assemble compounds has been an efficient method for constructing a compound library. We have developed one-pot tandem copper-catalyzed azidation and CuAAC reactions that afford 1-thiazolyl-1,2,3-triazoles with anticancer activity. By utilizing this one-pot synthetic strategy, we constructed a library of 1-thiazolyl-1,2,3-triazoles in search of the potent lead compound. Furthermore, 1-thiazolyl-1,2,3-triazoles were evaluated for anticancer activity against the multidrug-resistant cancer cells MES-SA/Dx5. Most of the 1-thiazolyl-1,2,3-triazoles revealed cytotoxic effect against cancer cells at micromolar to low micromolar range. Testing some of the most potent compounds (54,2-4} and 55,1-3}) against the normal cell line Vero showed no significant toxicity (except 54,2}) to normal cells. This result indicates that compounds 54,3-4} and 55,1-3} possessed good potency and selectivity to cancer cells over normal cells.
