All the compounds have been confirmed their structure by using UN, IR, 1HNMR and 13CNMR spectroscopy analysis. Generally, all the compounds showed cytotoxicity activity with IC50 value 15 – 80 ppm against murine leukemia (P-388) cell lines. The results showed that 3i could inhibit the highest P-388 cell line growth percentage.encurcumincondensationClaisen-SchmidtcytotoxicityP388UR-Proceedings
