Abstract:
Furan-containing congeners of the histamine H(2) receptor antagonist ranitidine were synthesized and tested for improgan-like antinociceptive activity. The most potent ligand of the series, VUF5498, is the most potent improgan-like agent described to date (ED(50)=25 nmol, icv). This compound is approximately equal in potency with morphine. These non-imidazole, improgan-like pain relievers further define the structural requirements for analgesics of this class and are important tools for ongoing mechanism-based studies.
