Abstract

A new class of pyridobenzophenoxazine compounds has been developed as topoisomerase II inhibitors for anticancer chemotherapy. These compounds were designed based on a proposed model of a quinobenzoxazine self-assembly complex on DNA. They showed excellent inhibitory effects on several tumor cell lines with nanomolar IC50 values. Their cytotoxic potency correlates with theft ability to unwind DNA and inhibit topoisomerase II.
