摘要
In this paper, we described the synthesis of 2-aminoflfiazole sublibrary containing methyl, bromo, phenylor butylidene at 4- or/and 5-position of its core. All target compounds were evaluated tbr their antitumor activitiesagainst human lung cancer cell line H1299 and human glioma cell line SHG-44. Among the compotmds screened,4,5,6,7-tetrahydrobenzo[d]thiazole（26b） exhibited the most potent antittunor activities with IC50 values of 4.89 and4.03 μmol/L against the two tested cell lines, respectively. Preliminary structure-activity relationship（SAR） studies ofthese compound were subsequently investigated.
