A method of making a phosphono-substituted dipyrromethane comprises reacting an aldehyde or acetal having at least one phosphono group substituted thereon with pyrrole to produce a phosphono-substituted dipyrromethane; and wherein the phosphono is selected from the group consisting of dialkyl phosphono, diaryl phosphono, and dialkylaryl phosphono. Additional methods, intermediates and products are also described.
The present invention is directed to low toxicity boronated compounds and methods for their use in the treatment, visualization, and diagnosis of tumors. More specifically, the present invention is directed to low toxicity carborane-containing 5, 10, 15, 20-tetraphenylporphyrin compounds and methods for their use particularly in boron neutron capture therapy (BNCT) and photodynamic therapy (PDT) for the treatment of tumors of the brain, head and neck, and surrounding tissue. The invention is also directed to using these carborane-containing tetraphenyl porphyrin compounds to methods of tumor imaging and/or diagnosis such as MRI, SPECT, or PET.

The present invention relates to a porphyrin metal complex represented by the formula (1): ##STR1## wherein R is a pivaloyloxy group, M is a transition metal ion of the group IV and the group V metals, X is a halogen ion, and n is 0 or 1. The above compound is used as a more stable artificial oxygen carrier capable of preventing the behavior of oxidation and deterioration.
A family of benzochlorins, a family of verdins, a family of porphyrin derivatives and metal complexes thereof are disclosed. The benzochlorins have the formula of FIG. 3 of the attached drawings; their metal complexes have the formula of FIG. 1 . The verdins have the formula of FIG. 4 of the attached drawings; their metal complexes have the formula of FIG. 2. The porphyrin derivatives have the formula of FIG. 7 of the attached drawings; their metal complexes have the formula of FIG. 8. Solutions of the benzochlorins, verdins, porphyrin derivatives and metal complexes which are physiologically acceptable for intravenous administration are also disclosed, as are emulsions or suspensions of the solutions, and compositions which additionally include cyclodextrin, and wherein the molecules of the benzochlorin, verdin, porphyrin derivative or metal complex are encapsulated within the molecules of the cyclodextrin. The solvent for the solutions can be a product of the reaction of ethylene oxide with castor oil. A method for detecting and treating tumors in human and animal patients is also disclosed. The method comprises administering one of the benzochlorins, verdins, porphyrin derivatives or metal complexes to the patient. For detection, the tumor area is then illuminated with ultra violet light; for treatment, the tumor area is illuminated with visible light of a wavelength at which the benzochlorin, verdin, porphyrin derivative or complex administered shows an absorption peak.

Novel methods of synthesizing heteroatom-containing chiral porphyrins and chiral metalloporphyrins and the novel chiral porphyrins and chiral metalloporphyrins themselves are disclosed. Metal complexes of the chiral porphyrins are prepared in high yields and shown to be active catalysts for highly enantioselective and diastereoselective cyclopropanation, aziridination, and epoxidation of alkenes under a practical one-pot protocol.
