What is Folate Receptor Alpha Targeted Delivery of Artemether to Breast Cancer Cells with Folate-decorated Human Serum Albumin Nanoparticles about?

The pharmaceutical application of artemether (ARM) as an anticancer natural agent is hampered due to its poor solubility and bioavailability. In the present study, ARM was encapsulated in human serum albumin nanoparticles (HSA NPs) via desolvation method led to improvement of the water solubility by 50 folds. In further, folate-decorated ARM-HSA NPs (F-ARM-HSA NPs) were developed to enhance targeted delivery to folate receptor alpha (FRα)-overexpressing breast cancer cells. The hydrodynamic diameter and the zeta potential value of F-ARM-HSA NPs were 198 ± 11.22 nm and -23 ± 0.88 mV, respectively. Fluorescent microscopy demonstrated an enhanced cellular uptake of F-ARM-HSA NPs by high FRα-expressing MDA-MB-231 breast cancer cells compared to low FRα-expressing SK-BR-3 breast cancer cells. Cytotoxicity assay revealed a small significant difference between cytotoxicity effect of targeted and non-targeted NPs in SK-BR-3 cells. However, in MDA-MB-231 cells due to FRα-mediated endocytosis, the F-conjugated NPs had less inhibitory concentration (IC50) value (19.82 μg/mL) and higher cytotoxicity after 72 h compared to non-targeted ARM-HSA NPs. Flow cytometry analysis indicated a more poten
