Nostocine a derivatives as human dna topoisomerase ii-alpha inhibitor

Abstract

Introduction: Due to heavy morbidity and mortality from cancer, the designing of newer drugable molecules against breast cancer is the call of day. As, Schiff-base sulfonamides have been widely used in tumor treatments. Methods: Nostocine-sulfonamide (NS) Schiff-base molecules were designed with tools of bioinformatics against the target enzyme, human topoisomerase II-alpha (topo IIa) against breast cancer. The designed NS conjugates were assessed by RO5, ADMET and molecular docking. Results: Herein, these analogues, NS-20b (Nostocine A-sulfaphenazole), 12a (Nostocine A-sulfisoxazole) and 16b (Nostocine A-sulfamethazineare) are N-heteroaryl substituted sulfonamide moieties linked with pyrazolo[4,3-e][1,2,4]triazine of Nostocine A. Conclusion: These derivatives would act as potent inhibitors of topo IIa for breast cancer.
