5-Chloromethyl-1-methyl-2-nitroimidazole reacted efficiently with the anion
derived from 5-bromo-isoquinolin-1-one to give 5-bromo-2-((1-methyl-2-nitr
oimidazol-5-yl)methyl)isoquinolin-1-one. Biomimetic reduction effected rele
ase of the 5-bromoisoquinolin-1-one. The 2-nitroimidazol-5-ylmethyl unit th
us has potential for development as a general prodrug system for selective
drug delivery to hypoxic tissues. (C) 1999 Elsevier Science Ltd. All rights
