A series of conjugates of 5-Fluorouracil (5-FU) and emodin were synthesized by coupling trimethyl emodin with N-1, N-3 dialkylated 5-FU. The 5-FU moiety contained various substituents at the N-3-position were linked to the 2-position of trimethyl emodin via a methylene linkage. Their cytotoxicity against three cancer cell lines and one noncancerous cell were studied. The results revealed that some of conjugates exhibited better or comparable in vitro antitumor activity to 5-FU and emodin and low toxicity in the normal cell. The structure activity relationship study showed N-3-aromatic substituent was important for their cytotoxic activity. (C) 2011 Elsevier Masson SAS. All rights reserved.
