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.

La présente invention se rapporte à un procédé de préparation de composés à base d'halogénure métallique de mésoporphyrine. Ledit composé d'halogénure métallique de mésoporphyrine peut être obtenu par le biais de la formation d'un nouveau composé intermédiaire de mésoporphyrine IX puis de la conversion de cet intermédiaire de mésoporphyrine IX en un halogénure métallique de mésoporphyrine par insertion d'un métal. Le nouveau composé intermédiaire peut être obtenu par hydrogénation catalytique d'une hémine dans de l'acide et extraction ultérieure.
