A synthesis of the neocarzinostatin chromophore analog 2, in which the 2'-N
-methylamino group of the natural product has been replaced by a hydroxyl g
roup, is described. Thiol addition experiments in organic solvents and DNA-
cleavage studies in aqueous solution are also described, and provide furthe
r support for the proposed participation of the carbohydrate methylamino gr
oup in neocarzinostatin activation. (C) 1999 Elsevier Science Ltd. All righ
