  • Title: Appending a tris-imidazole ligand with a Tyr 244 mimic on the distal face of bromoacetamidoporphyrin.
    Author: Collman JP, Decréau RA, Costanzo S.
    Journal: Org Lett; 2004 Mar 18; 6(6):1033-6. PubMed ID: 15012093.
    Abstract:
    [structure: see text] Bromoacetamidoporphyrin is a convenient synthon for the attachment of distal superstructures at room temperature in good yields. New models are presented that contain a tris-imidazole distal ligand set bound to the porphyrin in either a binary or trinary fashion. More importantly, one distal imidazole is cross-linked to a phenol mimicking Tyr(244), making this model the closest structural analogue yet reported of the metal free cytochrome c oxidase (CcO) active site.
