RGD-Conjugated Resveratrol HSA Nanoparticles as a Novel Delivery System in Ovarian Cancer Therapy.

Abstract

BackgroundTo establish a novel delivery system of RGD-conjugated resveratrol human serum albumin (HAS) nanoparticles in ovarian cancer therapy.MethodsThe 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.ResultsThe 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.ConclusionRGD-conjugated resveratrol HSA nanoparticles are an ideal drug delivery system, which can play a role in the treatment of ovarian cancer.
