Design, Synthesis, and Cytotoxicity of Indolizinoquinoxaline-5,12-dione Derivatives, Novel DNA Topoisomerase IB Inhibitors
Keyword(s):
A series of new indolizinoquinoxaline-5,12-dione derivatives were designed and synthesized via a heterocyclization reaction of 6,7-dichloroquinoxaline-5,8-dione with active methylene reagents and pyridine derivatives. The synthesized compounds exhibited significant activity to inhibit the growth of four human tumour cell lines, including lung adenocarcinoma cell, large-cell lung carcinoma cell, breast carcinoma cell, and ardriamycin-resistant breast carcinoma cell at micromolar range. These compounds were also investigated for their inhibition to DNA topoisomerase IB activity. The results indicated that the indolizinoquinoxaline-5,12-dione structure might be a potential pharmacophore in anti-cancer drug design.
