SPECIFIC PROTONATION OF THE CARCINOGEN 7, 12-DIMETHYIBENZ [a]ANTHRACENE AND CHARGE LOCALIZATION IN THE a-COMPLEX (open access)

SPECIFIC PROTONATION OF THE CARCINOGEN 7, 12-DIMETHYIBENZ [a]ANTHRACENE AND CHARGE LOCALIZATION IN THE a-COMPLEX

In the class of the polycondensed aromatic hydrocarbons, the concept of localized charge in a {sigma}-complex, e.g., the carbonium ion formed by addition of a proton or other electrophile to an aromatic ring, has so far received experimental evidence only in the case of anthracene. The ultraviolet spectrum of this compound in sulfuric acid is similar to that of the benzhydryl cation. Ph{sub c}C{sup +}Me. This result implies the protonation of anthracene at one meso-carbon atom and the localization of the positive charge at the other. The {sigma}-complex of the potent carcinogen 7,12-dimethylbenz[a]anthracene (DMBA) in acidic medium offers another example of this type of charge localization. The determination of structure was achieved by comparing the NMR spectra of DMBA in neutral and acidic solvents. The ratio of the integrated intensities of the proton peaks in the spectrum of DMBA is, from right to left, 3:3:5:1:1:2:1. The assignment of the 7-CH{sub 3} ({sigma}3.00) and 12-CH{sub 3} ({sigma}3.29) resonances was made by comparison with the spectra of 7-methylbenz[a]anthracene (7-CH{sub 3}, {sigma}3.03) and 12-methylbenz[a]anthracene (12-CH{sub 3}, {sigma}3.32) under the same conditions. A good general correlation exists between the methyl chemical shifts of the twelve monosubstituted methylbenzanthrancenes and the corresponding aryl protons of benzanthracene.

Mechanism Op Action Op P-Hydroxybenzoate Hybrozylase Frompseudomonas Putida. Iii. The Enzyme-Subtrate Complex (open access)

Mechanism Op Action Op P-Hydroxybenzoate Hybrozylase Frompseudomonas Putida. Iii. The Enzyme-Subtrate Complex

The mechanism of action of p-hydroxybenzoate hydroxylase from Pseudomonas putida, strain M-6, has been investigated. The aromatic substrate analogues, benzoate, p-fluorobenzoate, p-chlorobenzoate, p-nitrobenzoate, p-aminobenzoate, and 6-hydroxynicotinate, are found to be competitive inhibitors. This finding differs from the previously reported noncompetitive behavior in a different buffer system. The optical activity of the enzyme-inhibitor complex is studied. From the kinetic and circular dichroism (CD) measurements, they have found that the carboxyl moiety is necessary and sufficient for the enzyme-substrate binding, whereas the hydroxyl group alone will not lead to binding. There are two classes of inhibitory analogues: one causes changes in CD spectra of the enzyme similar to those evoked by the substrate, and the other does not cause significant changes. the results indicate that more than one mode of enzyme-inhibitor interaction is involved. The CD of the enzyme-NADPH complex under anaerobic conditions suggests that the oxidized enzyme and reduced pyridine nucleotide form a complex, both in the absence and presence of the substrate, p-hydroxybenzoate. Furthermore, evidence for a ternary complex is given.
