Abstract
Two series of 1,6-dimethyl-3-phenoxymethylquinoxalin-2-ones and 1-benzyl-3-phenoxymethyl-7- trifluoromethylquinoxalin-2-ones, and a series of 2-benzyloxy-3-phenoxymethyl-7-trifluoromethylquinoxaline were synthesized. Their capability to restore/potentiate the antiproliferative activity of clinically useful drugs, such as doxorubicin (Doxo), vincristine (VCR) and etoposide (VP16), in drug-resistant human nasopharyngeal carcinoma KB cells (KBWT, KBMDR, KB7Dand KBV20C) was evaluated. In vitro data show that many quinoxalin-2-ones and quinoxalines potentiate the antiproliferative activity of Doxo and VCR in tumor-derived MDR cell lines. In this series, 17a turned out to be the most potent quinoxaline derivative in potentiating the antiproliferative activity of doxorubicin and vincristine against KBMDR and KBV20C resistant cell lines, respectively.
