Abstract: Three new quinazoline derivatives 5a~5c bearing piperazine have been designed and synthesized by four-step reactions of cyclization, chlorination, substitution and condensation using 2-amino-5-chlorobenzoic acid and formamide as starting materials. Their structures were confirmed by 1H NMR, 13C NMR, ESI-MS and IR. The in vitro cytotoxicities against SGC-7901(human gastric cancer), KB(human oral epidermoid cancer) and HT-1080(human fibrosarcoma) cell lines of compounds 5a~5c were tested with colorimetric MTT assay. The results indicated that compounds 5a~5c had poor anticancer activities against SGC-7901 and HT-1080 cell lines, while had no notable inhibitory activity against KB cell lines.

Key words: chloropiperazinquinazoline N-thiosemicarbazone substituted derivatives, antitumor activity, MTT assay,synthesis
