- The self-assembly of 5-fluorouracil dilysine conjugates into self-supporting hydrogels, comprised of entangled nanofibers or rigid nanotubes with diameters of 10 and 16 nm, respectively, is reported. The rate of release of 5-Fu from the conjugates was highly dependent on concentration in solution, whereas, release from the fully formed hydrogels was significantly slower. The 5-Fu conjugate also exhibited promising in vitro cytotoxicity against human tumor cell lines A549, H460 and H23.
