Synthesis of methyl pyropheophorbide-a pyrazole derivatives and their in vitro cell viabilities on A549 cells Oyunbileg Galindev, Narangerel Badraa and Young Key Shim* DOI: 10.1142/S1088424607000953 Page: 829-835 In the present study, methyl pyropheophorbide-a derivatives containing unsubstituted and substituted pyrazole moiety in the peripheral position were synthesized in no less than 65% yield. In addtion, their in vitro cell viability for photodynamic therapy (PDT) was examined on A549 cancer cells. From the experimental results, the compounds 6 and 8 among the tested photosensitizers showed 48.1% and 46.2% cell viability after 3 h and, 44.1% and 43.4% after 24 h at 1.25 μM, respectively.
Effects of substituted metal-free porphyrins in apo-horseradish peroxidase A. Molaei Rad, A. Akbar Moosavi-Movahedi*, Hedayatollah Ghourchian, Nasser Safari, Jun Hong, Zinab Moosavi-Movahedi, Khodadad Nazari, A. Akbar Saboury and P. Rajabali Jamaat DOI: 10.1142/S1088424607000965 Page: 836-845 The peroxidase-like catalytic activities of some synthetic porphyrins following substitution in apo-horseradish peroxidase were comprised and studied. The results indicate that the free metal porphyrins coordinated correctly in an active site of apo-HRP, then adsorb metal-free ions from the environment and show peroxidase-like catalytic activity in the presence of hydrogen donors and H2O2.
Discotic liquid crystals of transition metal complexes 39: columnar mesomorphism and homeotropic alignment speed of sandwich-type of double-deckers and triple-deckers based on phthalocyaninato lutetium metal complexes Hidetomo Mukai, Kazuaki Hatsusaka and Kazuchika Ohta* DOI: 10.1142/S1088424607000977 Page: 846-856 A series of sandwich type of metal complexes, bis[2,3,9,10,16,17,23,24-octakis(3,4-dialkoxyphenoxy)phthalocyaninato]lutetium(III) were synthesized. As the by-product, tris[2,3,9,10,16,17,23,24-octakis(3,4-diakoxyphenoxy)phthalocyaninato]dilutetium(III) were successfully separated. Supplementary Material
Conformation and π-conjugation of olefin-bridged acceptor on the pyrrole β-carbon of nickel tetraphenylporphyrins: implicit evidence from linear and nonlinear optical properties Hsiu-Chih Yeh, Chin-Ti Chen*, Jenwei Yu*, Pei-Chang Tsai and Juen-Kai Wang* DOI: 10.1142/S1088424607000989 Page: 857-873 The controversial conformation and π-conjugation of olefin-bridged electron acceptor on pyrrole β-carbon of tetraphenyporphyrin nickel complexes was examined in detail. Both linear and nonlinear optical spectroscopies provide insightful into the questionable issues. Experimental and theoretical evidences imply that conformation is coplanar or near coplanar and π-conjugation connects the electron acceptor and porphyrin π-system. However, only a small portion of the porphyrin π-electron takes part in in the π-conjugation with electron acceptor.
Inclusion complex of iron meso-tetrakis(p-sulfonatophenyl)porphyrin and 2-hydroxypropyl-β-cyclodextrin as a functional model of cytochrome P-450; study on a supramolecular formation and its application in aqueous oxidation of styrene Hamid Reza Khavasi*, Koroush Sasan and Nasser Safari* DOI: 10.1142/S1088424607000990 Page: 874-882 Interaction of iron(III) meso-tetrakis(p-sulfonatophenyl)porphyrin, TPPS4FeCl, and 2-hydroxypropyl-β-cyclodextrin, HP-β-CD as a model of cytochrome P-450 enzyme was investigated and catalytic behavior of this inclusion complex was examined for the aqueous-catalytic oxidation of styrene and in different reaction conditions.
Ruthenium(II) meso-tetra-(benzo-15-crown-5)-porphyrinates: synthesis and spectroscopic investigation Yuliya Yu. Enakieva, Yuliya G. Gorbunova*, Aslan Yu. Tsivadze, Christine Stern and Roger Guilard* DOI: 10.1142/S1088424607001004 Page: 883-890 The synthesis of novel ruthenium(II) crown porphyrinates meso-[(B15C5)4Por]Ru(CO)(MeOH) (1) and meso-[(B15C5)4Por]Ru(L)2 (2)-(4) (L = py, pyz, 4,4’-bpy) are reported. The metalation of the free ligand performed by the reaction of Ru3(CO)12 with meso-[(B15C5)4Por]H2 gives (1) in a high yield. The synthesis of (2)-(4) implies the decarbonylation of (1) with trimethylamine N-oxide ((CH3)3NO) in the presence of the N-donor ligand. The composition of complexes were proved by variety of spectroscopic data. Supplementary Material
