Synthesis of hemin C from hemin
Journal of the Chemical Society, Chemical Communications, 1977Hemin C (2) was prepared in 45–50% yield by the reduction of a solution of iron protopophyrin IX [hemin (1)] and L-cysteine with sodium borohydride in the presence of oxygen and cetyltrimethylammonium bromide micelle.

Malaria parasites isolated from mouse erythrocytes are lysed by ferriprotoporphyrin IX chloride (hemin) or by a chloroquine-hemin complex in amounts that could be produced by release of less than 0.1 percent of the heme in erythrocytic hemoglobin.

Effects of free hemin on myocardium were investigated using a model of neonatal myocyte primary cultures. Cells were subjected to free hemin at concentrations up to 20 microM and equilibrated for 5 h at 37 degrees C. Distribution of hemin in media, cell sarcolemma, and cell interior was evaluated.

Catalytic nanographene oxide with hemin for enhanced photodynamic therapy.
Journal of Controlled Release, 2020Hypoxia is a hallmark of many malignant solid tumors. The inadequate oxygen concentration in the hypoxic regions of a solid tumor impedes the efficiency of photodynamic therapy (PDT) because the generation of reactive oxygen species during the PDT ...

Far-infrared studies on hemin and hemin-like complexes
Biochimica et Biophysica Acta (BBA) - General Subjects, 1971Abstract Far-infrared absorption spectra in the submillimeter region were observed at about 2°K on some halogen complexes of protoporphyrin (Fe3+) and tetraphenylporphyrin (Fe3+) using in Michelson interferometer. The D values in the spin Hamiltonian H = D [S Z 2 − 1 3 S(S+1)] which describes the ground sextet of the 3d ...
