Improvements in the synthesis of urazoles via a proposed transcarbamylation reaction are reported. Some experimental evidence for a transcarbamylation mechanism as indicated by the formation of identified intermediate products is shown. 13C n.m.r. studies on 1-phenyl-4-anilinourazole have settled the controversy on the structure of Pinner's compounds by establishing that they are 1,2,4-triazoles rather

(Co, Ni, Cu, Zn) was examined. Complexes CoCl2(Hur)2·4H2O (1), NiCl2(Hur)2·4H2O (2) and Zn(SO4)(Hur)·2H2O (3), in which urazine acts as neutral ligand, were synthesized and characterized. It is worth noting that in the examined crystal the chiral complex 3 shows only the A enantiomer due to a spontaneous resolution. Complexes Co(ur)2·4H2O (4), NiCl(ur)·H2O (5), CuCl(ur)·2H2O (6) and Zn(ur)2·2H2O (7)

A method for the identification and treatment of pathogenic microorganism infections by inhibiting one or more enzymes in a metabolic pathway by inhibiting the conversion of substrate to produce the penultimate or ultimate product particularly by inhibiting the activity of one or more of the enzymes in the pathway, and compounds and pharmaceutical compositions for inhibiting infections of pathogenic microorganisms by inhibiting such enzymes.

and LDL levels and decreased NO concentration and HDL level compared to the control group (p < 0.05). However, HFD plus urazine derivatives significantly decreased NO, cholesterol, and triglyceride levels and increased HDL levels compared to the HFD-treated group (p < 0.05). Urazine derivatives may improve liver dysfunction in HFD-induced hyperlipidemic rats by modulation of detoxification enzymes and
