Dramatic Influence of an Anionic Donor on the Oxygen-Atom Transfer Reactivity of a MnV–Oxo Complex
Addition of an anionic donor to an Mn(V) (O) porphyrinoid complex causes a dramatic increase in 2-electron oxygen-atom-transfer (OAT) chemistry. The 6-coordinate [Mn(V) (O)(TBP8 Cz)(CN)](-) was generated from addition of Bu4 N(+) CN(-) to the 5-coordinate Mn(V) (O) precursor. The cyanide-ligated complex was characterized for the first time by Mn K-edge X-ray absorption spectroscopy (XAS) and gi...

Driving force for oxygen-atom transfer by heme-thiolate enzymes.
The heme-thiolate peroxygenase from Agrocybe aegerita (AaeAPO, EC 1.11.2.1) is a versatile biocatalyst and cytochrome P450 analogue which catalyzes a variety of oxygenation reactions with high efficiency and selectivity. Our recent kinetic characterization of AaeAPO-catalyzed reactions has shown that AaeAPO compound I is an oxo-Fe porphyrin radical cation. The reactivity of AaeAPO-I toward a pa...
متن کاملGene Transfer Enhancement by Alkylcarboxylation of Poly(propylenimine)
Abstract Among synthetic carriers, dendrimers with the more flexible structure have attracted a great deal of researchers’ attention in the field of gene delivery. Followed by the promising results upon hydrophobic modification on polymeric structures in our laboratory, alkylcarboxylated poly (propylenimine)-based carriers were synthesized by nucleophilic substitution of amines with alkyl moiet...
