The thermal condensation of formamide in the presence of mineral borates is reported. The products afforded are precursors of nucleic acids, amino acids derivatives and carboxylic acids. The efficiency and the selectivity of the reaction was studied in relation to
Chemical biology & drug design, 70(1), 30-39 (2007-07-17)
The kinetics of formation and identity of the reaction products of the glucuronic acid with three representative opioid peptides were investigated in vitro. Peptides were conjugated with glucuronic acid either in solution or under dry-heating conditions. From the incubations performed

Pyridine and its metabolites have been shown in previous studies to induce cytochrome P4501A1 (CYP1A1) expression in vivo in the rat and in vitro in cultured human lung explants. In this study, we assessed the role of the metabolites in
Journal of molecular modeling, 8(3), 81-86 (2002-07-12)
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.
