Morphological analysis was conducted using optical microscopy and transmission electron microscopy (TEM) . The solubility of hinokitiol at different pH levels was determined, and the in vitro release profile of the optimized phytosomes was assessed. Cytotoxicity assays were performed to evaluate the anticancer efficacy against breast cancer cell lines, and apoptosis induction was examined using Annexin V/propidium iodide staining. Cell cycle analysis was conducted to assess the impact on cell cycle progression.\u003Cbr>Results: The optimized phytosomes demonstrated a size range of 138.4 ± 7.7 to 763.7 ± 15.4 nm, with zeta potentials ranging from −10.2 ± 0.28 to −53.2 ± 1.06 mV and entrapment efficiencies between 29.161 ± 1.163% and 92.77 ± 7.01% . Morphological characterization confirmed uniformity and spherical morphology. Hinokitiol solubility increased with pH, and the release from the optimized phytosomes exhibited sustained patterns. The formulated phytosomes showed superior cytotoxicity, with lower IC50 values compared to pure hinokitiol. Treatment induced significant apoptosis and cell cycle arrest at the G2/M and S phases.\u003Cbr>Conclusion: Hinokitiol-loaded phytosomes demonstrate promising anticancer efficacy against breast cancer cells, highlighting their potential as targeted therapeutic agents for breast cancer therapy.\u003Cbr>Keywords: hinokitiol, phytosomes, cytotoxic activity, breast cancer, apoptosis, cell cycle |\n| --- |\n| Introduction\u003Cbr>Breast cancer is a prevalent disease, impacting the lives of millions of women worldwide, making it one of the most pressing health challenges of our time. Its widespread occurrence underscores the urgent need for innovative and effective therapeutic strategies.1 In 2020, the global burden of breast cancer was staggering, with new cases totaling 2.3 million, accounting for approximately 11.7% of all cancer incidents. Projections based on global demographic trends paint a troubling picture for the future, with anticipated cases and deaths on the rise. Trailing closely behind are lung, colorectal, prostate, and stomach cancers. Despite this shift, lung cancer remains the primary cause of cancer-related deaths, claiming an estimated 1.8 million lives. However, female breast cancer follows closely behind, underscoring the urgent need for continued research, prevention, and treatment efforts to combat this pervasive disease.2,3 By 2040, the worldwide burden of cancer is projected to reach 28.4 million cases, marking a significant 47% increase from the levels observed in 2020.4 The anticipated increase is expected to be particularly pronounced in developing nations, where projections indicate a sharp rise in prevalence from 64% to 95% .
