Abstract
Current research work aimed to design, characterize and optimize gemcitabine (GCB) cubo-somes for the effective treatment of breast cancer. Cubosomes were developed by using solvent evaporation technique and optimized using 32 Factorial design to verify effect vesicle size and entrapment efficiency using poloxamer-407 (P-407) as emulsifier and glyceryl monooleate (GMO) as lipid. The optimized GCB cubo-somes were characterized for morphology by transmission electron microscope (TEM), crystalline by X-ray diffraction (XRD), in vitro release, in vitro cytotoxicity, apoptotic potential, etc. Optimized GCB cubosomes have a mean vesicle size of 184.2±3 nm with PDI 0.230± 0.046, zeta potential-28.1±2.73 mV, and entrapped 94.48± 4.54 % of GCB. Furthermore, the GCB cubosomes demonstrated significantly (p < 0.01) higher in vitro cytotoxic and apoptotic activity against breast cancer (MCF-7) cells after 48 hr of incubation. Hence, the developed GCB cubosomes can be used as a competent alternative to systemic chemotherapy in the effective management of breast cancer.
