Topoisomerase I/II-IN-1 is a dual inhibitor of topoisomerase I/II. Topoisomerase I/II-IN-1 induces G2/M arrest and apoptosis in cancer cells by upregulating p53, p21, and Bax mRNA levels, caspase-3 protein levels, and the Bax/Bcl-2 ratio, while downregulating Bcl-2. Topoisomerase I/II-IN-1 is useful in the study of various cancers, including melanoma, renal cancer, colorectal cancer, and breast cancer[1].
