New Cancer Therapy Study Findings Have Been Reported by Investigators at Huazhong University of Science and Technology

February 19, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Research findings on Oncology are discussed in a new report. According to news originating from Wuhan, People's Republic of China, by NewsRx correspondents, research stated, "Prodrug development is an important strategy for improving tumor cell targeting and the selectivity of anticancer drugs. In this study, poly(ethylene glycol) and melphalan, an anticancer drug, were linked to the backbone of hyaluronic acid via amide bonds using carbodiimide chemistry to synthesize a poly(ethylene glycol)-hyaluronic acid-melphalan prodrug."

Our news journalists obtained a quote from the research from the Huazhong University of Science and Technology, "The physicochemical properties of the prodrug were characterized by Fourier transform infrared, proton nuclear magnetic resonance, ultraviolet-visible spectroscopy, and dynamic light scattering and transmission electron microscopy. The in vitro drug release profiles and the corresponding in vitro cell evaluation of the prodrug were investigated. The poly(ethylene glycol)-hyaluronic acid-melphalan prodrug was successfully synthesized and self-assembled into 116.4-nm nanoparticles. The release profiles demonstrated that controlled release of the prodrug could be achieved with a sensitive property involving both pH and enzymatic degradation. The poly(ethylene glycol)-hyaluronic acid-melphalan prodrug was more effectively transferred into the ovarian tumor cell (SKOV3) than into human ovarian fibroblast (HOF) cells. It also had a higher inhibition effect on SKOV3 and a lower inhibition effect on HOF than melphalan."

According to the news editors, the research concluded: "This poly(ethylene glycol)-hyaluronic acid-melphalan prodrug, with its controlled release properties and selectivity, is a promising drug delivery system for cancer therapy."
