Design, synthesis and anticancer activity of novel dihydrobenzofuro[4,5-b][1,8]naphthyridin-6-one derivatives
摘要:
On the basis of the chemical structures of psorospermin with a xanthone template and acronycine derivatives with an acridone template, rac-1 and rac-2 constructed on an 1,2-dihydrobenzofuro[4,5-b] [1,8] naphthyridin-6(11H)-one scaffold were designed and synthesized as potential anticancer agents. Their anticancer activities were evaluated against five human cancer cell lines. Rac-2 showed similar anticancer activity to doxorubicin and rac-1 exhibited even higher anticancer activity against LNCaP (IC50 = 0.14 mu M), DU145 ( IC50 = 0.15 mu M), PC3 ( IC50 = 0.30 mu M) and MCF-7 ( IC50 = 0.26 mu M) cancer lines than doxorubicin and rac-2. Also, rac-1 revealed very potent anticancer activity ( IC50 = 0.15 mu M) against MCF-7/ADR cell (doxorubicin-resistant breast cancer cell) lines and induced G2/M phase arrest of the cell cycle in MCF-7/ADR cells.
