The reaction of Hg(CF3CO2)2 with metalloporphyrins produces mercurated porphyrins regioselectively, the reaction, surprisingly occurring at the most hindered betaB-position; this behavior is in marked contrast to the usual electrophilic substitution reactions of porphyrins, whose reactions produce meso-substituted porphyrins; the obtained mercurated porphyrins are active to transition metal-cat...

Anthracene and related compounds function as lifetime-extending cofactors in the (meso-tetraphenylporphine)Mn(III) chloride-catalyzed epoxidation of olefins. An experiment with a chiral porphyrin catalyst shows that enantioselectivity is preserved in the presence of the cofactor. Additional experiments show that (a) turnover number enhancement is greatest for the least reactive substrates, (b) ...

Encapsulation of glycosylated porphyrins in silica nanoparticles enhanced the efficacy cancer photodynamic therapy compared with free porphyrins.

Porphyrins from 38 cases of different types of porphyria were separated chromatographically and analyzed. Patients with different types of porphyria eliminated porphyrins with different patterns. Simple paper chromatography of the methyl ester of the total porphyrin of a urine sample revealed a chromatographic pattern of the porphyrins characteristic of the type of porphyria. The relative abund...

In order to shed more light on the effect of peripheral groups of porphyrin core intophysicochemical properties and DNA binding behavior of porphyrins, we have chosen toinvestigate solution properties and calf thymus DNA binding behavior of meso-tetrakis (4-Nbenzyl-pyridyl) porphyrin (TBZPyP) and its Mn (III), Co (III), Ni (II) and Cu (II) complexesderivatives have been studied in thermodynamic...
