Abstract
A series of novel quinazolinone derivatives was designed and synthesized. The antiproliferative activities were evaluated in vitro using MTT assay against hepatocellular carcinoma (HepG-2) and mammary gland breast cancer (MCF-7). The preliminary bioassay results demonstrated that tested compounds exhibited antiproliferation with various degrees. Triazole moiety enhanced the activity against the two cell lines when incorporating with quinazolinone moiety in a single molecular framework. Acetohydrazide-quinazolinone derivative showed strong activity against the two cancer cells comparable to that of doxorubicin. Biological evaluation indicated that all the tested compounds possessed antiproliferative activity with certain degrees.
