Metal complexes of 3-hydroxypyridine-2-carboxylic acid (H(2)hpic), [Co(Hhpic)(2)(H(2)O)(2)] (1), [Fe(Hhpic)(2)(H(2)O)(2)] (2), [Zn(Hhpic)(2)(H(2)O)(2)] (3), [Mn(Hhpic)(2)(H(2)O)(2)] (4), and [Cu(Hhpic)(2)] (5) have been synthesized and characterized by mass spectrometry, elemental analysis, magnetic susceptibility, infrared, electronic absorption and electron paramagnetic resonance (EPR) spectroscopies. The solid-state

Photoprotective activity of heteroaromatic compounds (derivatives of 3-hydroxypyridine, amino-6-hydroxybenzothiazole, and 5-hydroxybenzimidazole) was studied in the system of UV-induced cardiolipin peroxidation. Although all three compounds had the antioxidant effect during free radical oxidation of luminol, only derivatives of amino-6-hydroxybenzothiazole and 5-hydroxybenzimidazole

Molecular mechanics and semiempirical calculations using HyperChem 5 were carried out to investigate whether the results obtained can explain why 2-hydroxypyridine is far more soluble in water than 3-hydroxypyridine. The results of molecular mechanics calculations show that in solution in
Tyrosine phenol-lyase from Citrobacter freundii synthesizes 2-aza-L-tyrosine and 3-aza-L-tyrosine from 3-hydroxypyridine and 2-hydroxypyridine, respectively, and ammonium pyruvate.
