| Summary: | The objective of this study was to hydrophobically modify fenugreek gum (FG) and to further evaluate the potential application of the obtained derivative in liver-targeted drug delivery system. Stearic acid (C18) was conjugated with FG (FG-C18) by a simple esterification reaction. The obtained FG-C18 was then characterized on its chemical structure by Fourier transform infrared spectroscopy and 1H-nuclear magnetic resonance. The self-assembled nanomicelles (NMs) of FG-C18 in water were prepared by an ultrasonication method. The average diameter and zeta potential of FG-C18 NMs were 196.70 ± 6.12 nm and −31.79 ± 1.58 mV, respectively. FG-C18 NMs appeared as spherical particles under transmission electron microscopy and possessed a critical micellar concentration of 0.042 mg/ml by pyrene fluorescence probe method. A low toxicity of FG-C18 was revealed on both HepG2 and MCF-7 cells at 0.1–100 mg/ml. Haemolysis of FG-C18 was less than 5%. Cellular uptake of coumarin-6 into HepG2 cells was enhanced by treating with C6-loaded FG-C18 NMs compared to free coumarin-6. These results suggest that FG-C18 have a potential application for a liver targeted drug delivery. |
