  • Methods for synthesizing metal mesoporphyrins
    Patent number: 8735574
    Abstract: Embodiments describe methods of synthesizing metal mesoporphyrin compounds. In embodiments, a metal mesoporphyrin compound may be formed by hemin transmetallation and subsequent hydrogenation of the tin protoporphyrin IX to form a metal mesoporphyrin. In other embodiments, a method of synthesizing a metal mesoporphyrin compound comprises forming a protoporphyrin methyl ester from hemin and converting the protoporphyrin methyl ester intermediate to a metal mesoporphyrin compound through metal insertion and hydrogenation. In other embodiments, a metal mesoporphyrin compound may be formed from hemin by a hydrogen-free hydrogenation method to form a mesoporphyrin IX intermediate followed by metal insertion and hydrogenation. In embodiments, a method of synthesizing a metal mesoporphyrin compound comprises forming a mesoporphyrin IX dihydrochloride intermediate compound and converting the mesoporphyrin IX intermediate to a metal mesoporphyrin compound through metal insertion.

  • Preparation of metal mesoporphyrin compounds
    Patent number: 7777028
    Abstract: A method of preparing metal mesoporphyrin halide compounds is described. The metal mesoporphyrin halide compound may be formed by forming a novel mesoporphyrin IX intermediate compound and then converting the mesoporphyrin IX intermediate to the metal mesoporphyrin halide through metal insertion. The novel intermediate compound may be formed by a catalytic hydrogenation of hemin in acid and subsequent recovery.
