  • Publication number: 20140106367
    Abstract: Porphyrinic compounds that contain solubilizing groups are described, along with methods of making and using the same and compositions comprising such compounds. Examples of such compounds include compounds of Formula I: wherein: Z is a porphyrinic macrocycle, Alk1 and Alk2 are each independently an alkylidene chain; L is a linking group or is absent; R1 is preferably an ionic group or polar group; R2 is an ionic group, polar group, bioconjugatable group, or targeting group; R3 is present or absent and when present is a halo group, bioconjugatable group, or targeting group, n is O or 1 (that is, the CH group is present, or Alk1 and Alk2 are bonded directly to a carbon of the porphyrinic macrocycle Z); or a salt thereof.
