Inhibition of nitrite-mediated N-nitrosation of dimethylamine, morpholine and N-methylaniline by tea extracts and by 6 individual catechins in the extracts was studied. The inhibitions were detected by quantifying the nitrosamines formed. Eight diffe

Azothiopyrine and methyl-azothiopyrine were synthesized as new chelating agents which form stable chelates with some metal ions at the mercapto and azo groups. Azothiopyrines are unusually stable in solution because of a strong intramolecular hydroge

New water-soluble chelating agents, azothiopyrine sulfonates, which possess mercapto and azo groups as a chelate-forming site and a sulfonic acid group as a functional group providing water-solubility, were prepared. Their acid dissociation constants
