SP-96 is a highly potent, selective, and non-ATP-competitive inhibitor of Aurora B kinase, with an IC₅₀ of 0.316 nM. It exhibits exceptional selectivity, showing over 2000-fold greater specificity for Aurora B compared to off-target kinases such as FLT3 and KIT. In NCI-60 cancer cell line screening, SP-96 demonstrates selective antiproliferative activity, notably against the triple-negative breast cancer (TNBC) cell line MDA-MB-468 (GI₅₀ = 107 nM). SP-96 is a valuable tool for investigating Aurora B–driven oncogenic pathways and holds promise for the development of targeted therapies in TNBC and other malignancies.
