NK314 (Cat No.: I008311) is a potent topoisomerase IIα inhibitor with strong anticancer activity, particularly effective against drug-resistant tumor cells. By stabilizing the topoisomerase II-DNA complex, NK314 induces DNA double-strand breaks, leading to apoptosis in rapidly proliferating cancer cells. It shows high selectivity for topoisomerase IIα over IIβ, reducing potential cardiotoxicity. NK314 has demonstrated efficacy in preclinical models of leukemia and solid tumors, making it a promising candidate for cancer therapy and a valuable tool for studying topoisomerase-related mechanisms in oncology.
