2-Nitroimidazol-5-ylmethyl as a potential bioreductively activated prodrug system: reductively triggered release of the parp inhibitor 5-bromoisoquinolinone
摘要:
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-nitroimidazol-5-yl)methyl)isoquinolin-1-one. Biomimetic reduction effected release of the 5-bromoisoquinolin-1-one. The 2-nitroimidazol-5-ylmethyl unit thus has potential for development as a general prodrug system for selective drug delivery to hypoxic tissues. (C) 1999 Elsevier Science Ltd. All rights reserved.

Regioselective methods were investigated to prepare N- and O-alkylated isoquinolin-1-ones efficiently. The predicted regioselective alkylation of the nitrogen with (hetero)benzyl halides was complemented using (hetero)benzylic Mitsunobu electrophiles to alkylate predominantly at the oxygen. A series of drug-delivery conjugates was prepared demonstrating control over the site of alkylation. The Mitsunobu reaction provides a new approach to 1-alkoxyisoquinolines that were unavailable via previous harsher synthetic methods.
