Novel 6-(1H-1,2,3-triazol-4-yl)-imidazo[2,1-b]thiazoles 8-10 were synthesized in good yields by Claisen–Schmidt reaction of the active methylene compounds such as pyrazol-5-one 5, 1,3-indandione 6 and benzoylaceteonitrile 7, with imidazo[2,1-b]thiazol-5-aldehydes 4 in basic medium. Anti-tumor activities in vitro against HepG-2, PC-3 and HCT-116 human carcinoma cell lines were tested for new products. Both compounds 9a and 9b showed antitumor activity comparable to that of positive control (Doxorubicin®). Also, the antimicrobial activities of novel compounds were evaluated. Amongst the tested compounds 9a, 9b, and 10 exhibited excellent antimicrobial activity.
