Tailored Doxorubicin-Hyaluronan Conjugate as a Potent Anticancer Glyco-Drug : An Alternative to Prodrug Approach

• Releasibility of doxorubicin from drug-conjugates is believed to be a prerequisite for its anti- cancer activity. Here, a new glyco-drug approach that circumvents the releasibility restriction is reported, opening a new possibility to design efficient, target specific drug delivery system. It is discovered that stable amide coupling of doxorubicin (DOX) tohyaluronan (HA) shows dose dependent cytotoxicity to CD44 positive human coloncancer cells (HCT116) as compared to human breast cancer cells(MCF-7) and mouse fibroblast cells (NIH-3T3), which express less CD44 receptor. This direct conjugation approach is an easy scalable strategy that could be adopted to design innocuous anti-tumor nanoparticle formulations.
