We report a new series of biscyclohexano-fused Mn(III) complexes of bis(hydroxyphenyl)dipyrromethenes, 4a-c, as potent and orally active peroxynitrite scavengers. Complexes 4a-c are shown to reduce peroxynitrite through a two-electron mechanism, thereby forming the corresponding Mn(V)O species, which were characterized by UV, NMR, and LC-MS methods. Mn(III) complex 4b and its strained BODIPY analogue 9b were analyzed by X-ray crystallography. Finally, complex 4a is shown to be an orally active and potent analgesic in a model carrageenan-induced hyperalgesia known to be driven by the overproduction of peroxynitrite.
