Novel thiazonaphthalimides as efficient antitumor and DNA photocleaving agents: Effects of intercalation, side chains, and substituent groups
摘要:
A series of novel antitumor and DNA photocleaving agents was designed and synthesized by fusing a (substituted) thiazole ring to the naphthalimide skeletons. C-1, the most active compound against A549. was about 10-fold more cytotoxic than the compound amonafide. A,. the most active compound against P388, was about 6-fold more cylotoxic than amonafide. C-2, the most efficient DNA intercalator, showed the strongest DNA photocleaving activity Via Superoxide anion produced under UV light at 360 nm. (c) 2005 Elsevier Ltd. All rights reserved.
