The oxidative deamination of p-(N,N-dimethylamino)benzylamine and N-methyl-p-(N,N-dimethylamino)benzylamine by bovine liver monoamine oxidase B has been investigated by absorption spectral, steady-state, and stopped-flow kinetic studies. An absorbing intermediate with a maximum at 390 nm is observed with either analogue in turnover
Copper removal from pig kidney amine oxidase containing Cu/topaquinone (TPQ) has been obtained using CN(-) in the presence of the poor substrate p-(dimethylamino)benzylamine. Upon removal of copper, the enzyme loses its activity while the TPQ cofactor remains in its oxidized
Nitrobenzoid, nitroheterocyclic and cyanobenzoid compounds inhibit type B monoamine oxidase. A partially purified enzyme preparation from rabbit liver mitochondria, oxidizing rho-dimethyl-aminobenzylamine as the substrate, was competitively inhibited by nitrobenzoid compounds with K1 values in the range of 0.28 muM for

A selective and sensitive high-performance liquid chromatographic method with chemiluminescence detection for the determination of 5-hydroxyindoles is described, based on the reaction of 5-hydroxyindoles with 4-dimethylaminobenzylamine. Serotonin, 5-hydroxyindole-3-acetic acid, 5-hydroxytryptophol, 5-hydroxyindole-3-acetamide and N-acetyl-5-hydroxytryptamine were used as model compounds to optimize
Mild electrophilic C(sp2)-H cyclometalation of 2-phenylpyridine and N,N-dimethylbenzylamine by the chloro-bridged osmium(II) dimer [OsCl(micro-Cl)(eta6-C6H6)]2 in acetonitrile affords cyclometalated pseudotetrahedral OsII complexes [Os(C approximately N)(eta6-C6H6)(NCMe)]PF6 (C approximately N=o-C6H4py-kappa C,N (2) and o-C6H4CH2NMe2-kappa C,N (5), respectively) in good to excellent yields.
