Background: To establish a novel delivery system of RGD-conjugated resveratrol human serum albumin (HAS) nanoparticles in ovarian cancer therapy.
Methods: The nanoparticles system was characterized for physicochemical properties, the stability in the serum and in vitro release. The comparison between RVT injection, HSA-RVT NPs and RGD-HSA-RVT NPs regarding tissue distributions and pharmacokinetics was also carried out using mice as the animal models.
Results: The results showed that RGD-HSA-RVT NPs were characterized of small particle size about 128.2 nm and negative zeta potential about -21.42 mV, and drug controlled to release slowly on a biphasic pattern. Compared with control groups, RGD-HSA-RVT NPs showed the higher cellular uptake and cell inhibition rates. In vivo data showed that RGD-HSA-RVT NPs have good tumor enrichment characteristics and a significant difference in tumor inhibition, compared with the control group.
Conclusion: RGD-conjugated resveratrol HSA nanoparticles are an ideal drug delivery system, which can play a role in the treatment of ovarian cancer.
