Synthesis and antiproliferative activity of indolizinophthalazine-5,12-dione derivatives, DNA topoisomerase IB inhibitors
摘要:
A series of novel indolizinophthalazine-5,12-dione derivatives were designed and synthesized by the reaction of 6,7-dichlorophthalazine-5,8-dione with active methylene reagents (AMR) and pyridine derivatives. Some of synthesized compounds exhibited significant in vitro antiproliferative activity at micromolar level toward four human tumor cell lines, including lung adenocarcinoma cell, large-cell lung carcinoma cell, breast carcinoma cell and ardriamycin-resistance breast carcinoma cell. The DNA topoisomerase IB inhibitory assay indicated that DNA topoisomerase IB might be a biological target of the synthesized compounds. (C) 2010 Published by Elsevier Masson SAS.

a base to develop novel DNA topoisomerase IB (TOP1) catalytic inhibitors. In this work, twenty-three novel indolizinoquinolinedione derivatives were synthesized. TOP1-mediated relaxation, nicking and unwinding assays revealed that three fluorinated derivatives 26, 28 and 29, and one N,N-trans derivative 46 act as TOP1 catalytic inhibitors with higher TOP1 inhibition (++++) than camptothecin (+++) and
