“…On the other hand, at least for some reactions, it seems that one cannot completely rule out the possibility for the partners having extended n-orbitals to contact each other rather closely but still remaining in different monolayers. Danhauser et al [236] controlled the maximum depth of a manganese porphyrin embedding into the membrane by linking it to the hydrophilic polyethyleneimine. It has been shown that the electron exchange reaction of the type (41) proceeds only when the edge-to-edge distance between Mn(II) and Mn(III) porphyrins becomes less than 4 A.…”

“…The inclusion of porphyrins into monolayer, bilayer and micellular lipid aggregates forms supramolecular structures with unique physical-chemical properties [63,64] as do nanoformulations [65] . Also, phospholipid vesicles containing porphyrins have been prepared as model systems for haemoproteins for investigating O 2 transport systems [66] and electron transfer reactions [67] . Such vesicles have been observed under electron microscopes to be 100-150 nm in diameter [62] .…”

Abstract:This review presents an in-depth overview of the modification of porphyrins with bioconjugates and their applications in medicine today. Porphyrin bioconjugates ranging from nucleotides to steroids are under active scrutiny. However, carbohydrates have been at the forefront of such research in recent years and offer significant potential. This is attributed to their own selectivity to lectins on the surface of cancer cells and their influence on the amphiphilicity of the porphyrin macrocycle. These characteristics and the tendency of porphyrin photosensitizers to accumulate in tumor tissues make glycoporphyrins promising candidates for use as photosensitizers. Thus, a detailed overview of the synthesis and biological evaluation of glycoporphyrins is given with a particular focus on their applications in photodynamic therapy and their future prospects as drug candidates have been reported.

“…Liposome of eggPC containing PE-C n -NQ was prepared by the methods previously reported [4,14]. In brief, an aliquot of the desired PE-linked quinone dissolving in CHCl 3 was added into eggPC (100 mg) dissolving in a few milliliters of CHCl 3 and homogeneously mixed.…”

“…Quinones as well as porphyrin pigments play a key role in these electron transfers [9][10][11][12]. There has been little study of ground state electron transfer between quinones or porphyrins complexes to provide an insight into the effect of structure of quinones and porphyrins on the electron transfer so that a vectorial electron transfer system between quinones or porphyrins may be constructed in the membrane [13][14][15][16][17][18][19][20]. Runquist and Loach reported catalysis of electron transfer across phospholipid bilayers by iron-porphyrin complexes [19].…”
