Abstract:
This research aimed to evaluate the effect of variables on exemestane-loaded bovine serum albumin nanoparticles (EXE-BSA NPs) to improve anti-breast cancer activity. EXE-BSA NPs were optimized using 32 factorial design, wherein the concentration of BSA (X1) and sonication time (X2) were independent variables and particle size (Y1) and %w/w entrapment efficiency (Y2) were dependent variables. The statistical optimization revealed a significant effect of BSA concentration on both variables, whereas sonication time affected only particle size. The optimized EXE-BSA NPs were spherical with 124.1 ± 2.62 nm particle size, 83.95 ± 1.06% w/w drug entrapment, and exhibited a biphasic release of 100% (w/w) drug over 72 h. The optimized formulation induced cytotoxicity in MCF-7 cell lines with an IC50 value of 21.46 µg/mL by MTT assay, almost half the free drug (54.87 µg/mL). Thus, statistically optimized EXE-BSA NPs were effective in MCF-7 cell lines and can be explored to treat estrogen receptor-positive breast cancer.
