The metabolism of 2-amino-1-methyl-6-phenylimidazo[4,5-b]-pyridine (PhIP), a heterocyclic amine carcinogen detected in cooked meats, was investigated in mice. In 3-methylcholanthrene-induced mice administered 0.1, 1.0 and 10 mg/kg [14C]PhIP (i.p.), u

A new heterocyclic amine mutagen was isolated from a dry-heated reaction of the natural meat components creatine, glutamic acid and glucose. Heating creatine and glutamic acid alone had only one seventh of the Ames/Salmonella mutagenic activity of th

A new mutagenic compound has been isolated from ground beef which was fried at 300 degrees C for 5.5 min on each side. The new mutagen was purified using an aqueous acid extraction, XAD-2 adsorption-solvent elution, a series of preparative and analyt

It was reported earlier that methylcobalamin (MeB‐12) plus K2PtCl6 or Na2PtCl6 under acidic conditions yields a single square planar Pt2+ species, MePtCl2‐ 3. A reaction between MeB‐12 and PtCl4 in...

The aromatic amine mutagen, [14C]2-amino-3,4-8-trimethyl-imidazo[4,5-f]quinoxaline (4,8-DiMeIQx), which is derived from cooked food, was administered to conventional and germ-free AGUS rats previously fed either a semi-synthetic diet containing the c

Two mutagens isolated from fried-beef patties were compared to a series of synthetic structural isomers of 2-aminodimethylimidazo[4,5-ƒ]quinoxaline (MeIQx) and 2-aminotrimethylimidao[4,5-ƒ]quinoxaline (DiMeIQx). Comparison by NMR spectrometry and H

The interaction of Zn(II) with nucleotide triphosphates has been studied by /sup 35/Cl NMR and by /sup 1/H NMR. In 0.5 M NaCl solutions, enhanced /sup 35/Cl relaxation is produced by the metal ion in a Zn(II)-nucleotide triphosphate complex, Zn(NTP).
