N. Motohashi et al., REDUCTION OF MN3-TETRAKIS(4-METHYLPYRIDYL)PORPHINE WITH ALBUMIN OBSERVED IN RESONANCE RAMAN-SPECTRA(), Chemical and Pharmaceutical Bulletin, 46(3), 1998, pp. 551-553
When the resonance Raman spectra of Mn3+-tetrakis(4-methylpyridyl)-por
phine are measured in the presence of albumins, the resonance Raman ba
nds of Mn2+-tetrakis(4-methylpyridyl)porphine are frequently observed.
This reduction of Mn3+ to Mn2+ could be caused by an action of unfold
ing albumins resulting from heat and/or light.
