Abstract
Diosgenin as a potential phytoconstituent and steroidal saponin manifested significant anticancer agents against various cancers. To enhance its solubility and bioavailability in cancer treatment, we loaded diosgenin (PubChem CID: 99474) in poly(lactic-co-glycolide) (PLGA) nanoparticle coated with folic acid-chitosan (Da-PFC-NPs). The diosgenin nano-formulation was characterized and its antioxidant and anticancer properties were surveyed respectively. The obtained results illustrated that the Da-PFC-NPs were spherical and stable with a size of 218 nm and a polydispersity index of 0.41. The Da-PFC-NPs indicated potential free radical scavenging using ABTS and DPPH assay. Meanwhile, it demonstrated selective toxicity against the TUBO breast cancer cell with IC50 values of 104.45 μg/ml and did not show toxicity on normal cells (I929 cell line). The invivo funding exhibited that Da-PFC-NPs notably altered the liver enzymes (AST, ALT, ALP) and immunoglobulins (IgA, IgG, IgM). Besides that, different doses of Da-PFC-NPs (50 and 100 mg/kg) remarkedly enhance the expression of caspase 3 and decrease HER2 genes. In light of this experiment, we can conclude that Da-PFC-NPs have promise as novel carrier for improving the delivery of diosgenin in cancer therapy.
