Modeling the active sites of diiron and dicopper metalloproteins with napthyridine-, phthalazine-, and diethynylbenzene-based ligands
… Diiron(II) Complexes with a Sterically Hindered Phthalazine Ligand The synthesis and crystallographic characterization of a series of diiron(II) complexes with a sterically hindered bridging phthalazine ligand are presented. The compounds [Fe₂(Ph₄bdptz)([mu]-O₂CR)₂]²⁺ (R = CH₃ (3); C₂H₅ (4); …

Interaction of phthalazines with molybdenum hydroxylases. Phthalazine and its 1-substituted derivatives as substrates, inhibitors and inducers of aldehyde oxidase and xanthine oxidase, both in vitro and in vivo.
The interaction of the 2,3-diazanaphthalene, phthalazine and its 1-substituted derivatives with the molybdenum hydroxylases, aldehyde oxidase and xanthine oxidase, has been investigated both in vivo and /Ok in vitro. Metabolic studies, carried out by treating rabbits with both cold and 14C-labelled …

Reactivity of Aluminum Carbenoid with Unsaturated Substrates
… Finally, a reaction of NacNacAl with phthalazine produced a product of the N−N bond cleavage. NacNacAl reacted with a series of polycyclic aromatic hydrocarbons via [4+1] cycloaddition. While a reaction with anthracene was irreversible, with the formation of products of activation of …

Specificity of aldehyde oxidase towards N-heterocyclic cations. Oxidation of quinolinium and related cations by aldehyde oxidase in vitro; the isolation of two products formed simultaneously from a single substrate.
… same site on the enzyme. Km and Vmax values for phthalazine, N-methyl-2-phenylquinolinium and N-methylquinolinium were determined over the pH range 5.4 to 10.2. In each case, results indicated that the enzyme has an ionisable group at the active site with a pK ca. 8. Aldehyde oxidase was shown to …
