New syntheses of deuterated protoporphyrin-IX derivatives for heme protein nmr studies
, 1979 An efficient total synthesis of 1,5-di(trideuteromethyl)protoporphyrin-IX (3) dimethyl ester from monopyrrole precursors is described, the synthesis proceeding through crystalline tripyrrene and a,c-biladiene salt intermediates. The 2- and 4-vinyl groups

A new class of [2Fe-2S]-cluster-containing protoporphyrin (IX) ferrochelatases.
, 2006 Protoporphyrin (IX) ferrochelatase catalyses the insertion of ferrous iron into protoporphyrin IX to form haem. These ferrochelatases exist as monomers and dimers, both with and without [2Fe-2S] clusters. The motifs for [2Fe-2S] cluster co-ordination are

Paracoccidioides can internalize protoporphyrin rings.
, 2014 Iron deprived Pb01 and Pb18 yeast cells were incubated in MMcM medium supplemented or not (0) with different zinc protoporphyrin IX (Zn-PPIX) concentrations (20–100 µM) for 2 h. After this period, the cells were washed twice, and observed by bright field

Protoporphyrin-IX: Some useful substituent manipulations
, 1987 Various substituent manipulations of the side chains in commercially available hemin (3) and its metal-free derivative, protoporphyrin-IX (4), are described, which illustrate the usefulness of these starting materials for preparation of a large number of
