This activation mechanism has led to its exploration for repositioning applications in controlling and treating breast cancer, which express a Nitro reductase gene.Methods: NITRO Cubosomes were developed using hot homogenization according to 23-full factorial design. The factors studied included the ratio of drug to oily phase (1:10 and 2:10), the ratio of oily to aqueous phase (1:10 and 1:5), and the ratio of Glyceryl mono-oleate (GMO) to Poloxamer 407 (PX407) (0.25:1 and 0.5:1). A total of 8 systems were proposed and evaluated by measuring particle size, zeta potential, polydispersity index, and percentage of entrapment efficiency.Results: S6 (1:10 drug: oily phase, 1:5 oily: aqueous phase and 0.5:1 GMO: PX407) with particle size 45.5 ±c1.1 nm and an entrapment efficiency of 98.6 ± 1.8% exhibited highest desirability and was selected for further analysis. The morphology of S6 was examined using TEM microscopy. The activation of NITRO from S6 reflected on intracellular viability of MCF-7 breast cancer cell line was investigated by an MTT assay. The findings indicated that S6 had the lowest IC50 value (83.99 ± 0.15 μg g/mL) compared to Free NITRO (174.54 ± 1.36 μg g/mL), suggesting enhanced efficacy compared to free NITRO.Conclusion: Nitrofurantoin cubosomes can be candidates for repositioning in breast cancer management after encouraging further stability and in-vivo studies.Keywords: nitro reductase, glyceryl monooleate, Poloxamer 407, MTT assay, factorial design
