The durg-macromolecule conjugates i.e. 5-fluorouracil-1-acetyl-human serum albumin(FU-AA-HSA, 8) and 5-fluorouracil-1-acetyl-poly-L-lysine(FU-AA-polylys, 9) have been synthesized and purified by sephadex G-25 gel filtration with 0.05M phosphate buffer(pH 7.5). The analyses of conjugates gave the molar ratio of FU-AA : HSA of 70-100:1 and FU-AA: poly-L-lysine of 109:1. The weight percent of FU-AA(as $FU-CH_2CO-$) in FU-AA-HSA conjugate was 16-22% and the one in FU-AA-polylys was 22.4%.
