In order to find more effective antitumor agents, a series of novel dehydroabietic acid derivatives bearing nitrate moiety were designed and synthesized. Their cytotoxicities were evaluated against human cancer cell lines of CNE-2 (nasopharynx), HepG2 (liver), HeLa (epithelial cervical) and BEL-7402 (liver), and human normal liver cell (HL-7702) and nasopharyngeal epithelial cell (NP69) using methyl thiazolyl tetrazolium (MTT) assay. Biological screening results demonstrated that most of the hybrids exhibited more potent cytotoxicity superior to parent compound dehydroabietic acid. Among them, 12-bromodehydroabietic acid-3'-nitrooxypropyl ester (5j) displayed better antiproliferative activity with IC50value of (8.36±0.14) μmol/L toward CNE-2 cells compared with cisplatin, and 2,14-dinitrodehydroabietic acid-3'-nitrooxypropyl ester (5n) showed remarkable cytotoxicity with IC50 value of (11.23±0.21) μmol/L against BEL-7402 cells. Moreover, they exhibited lower cytotoxicity against human normal liver cell line HL-7702 and nasopharyngeal epithelial cell NP69. Besides, NO released amounts detection of all nitrates suggested that in most cases, the cytotoxicities were positively correlated with the levels of intracellular NO release in CNE-2 cells.
