Abstract
Aim: To investigate the pemetrexed encapsulated polymeric mixed micelles (PMMs) against breast cancer treatment.Methods: We meticulously optimized the formulation and conducted extensive characterizations, including photon correlation spectroscopy for micellization, advanced analytical techniques and in vitro cell line assessments.Results: The PMM exhibited favorable characteristics, with a spherical morphology, hydrodynamic particle size of 19.58±0.89nm, polydispersity index of 0.245±0.1, and a surface charge of -9.70±0.61mV. Encapsulation efficiency and drug payload reached 96.16±0.37% and 4.5±0.32%, respectively. Cytotoxicity analysis indicated superior efficacy of the PMM over the drug solution.Conclusion: The PMM formulation exhibited controlled release of the drug, and demonstrated enhanced cytotoxicity against breast cancer cells, highlighting its therapeutic promise.
