The present invention discloses a novel quinobenzoxazine self-assembly complex on DNA and on the topoisomerase II-DNA complex. The related model is used to design a new series of quinobenzoxazines, pyridobenzophenoxazines, pyrridonaphthophenoxazines, and other related compounds that may exhibit anticancer or antibiotic activity. The anticancer activity of these compounds is thought to operate via stabilization of the topoisomerase II-DNA complex and/or interaction with G-quadruplexes, while the antibiotic activity of these compounds derives from their ability to inhibit gyrase, the bacterial type II topoisomerase.
                            本发明揭示了一种新型的喹诺苯并噁嗪自组装复合物,可作用于DNA和拓扑异构酶II-DNA复合物。相关模型用于设计一系列新的喹诺苯并噁嗪、
吡啶苯并苯噁嗪、
吡啶萘苯噁嗪和其他相关化合物,这些化合物可能表现出抗癌或抗生素活性。这些化合物的抗癌活性被认为是通过稳定拓扑异构酶II-DNA复合物和/或与G四链体相互作用来发挥作用的,而这些化合物的抗生素活性则源于它们抑制细菌类型II拓扑异构酶酶的能力。
