Design and synthesis of a potent macrocyclic 1,6-napthyridine anti-human cytomegalovirus (HCMV) inhibitors

A novel class of macrocyclic 1,6-napthyridines designed to adopt the presumed bioactive conformation of anti-HCMV acyclic 1,6-napthyridines are described. Both 14- and 15-membered macrocycles were shown to be highly potent against HCMV HSV-1 and HSV-2.
