摘要：

4,4′-Dihydroxyphenazone (4-hydroxy-1-(4′-hydroxyphenyl)-2,3-dimethyl-3-pyrazoline-5-one) was isolated as a metabolite of phenazone (antipyrine) after acid hydrolysis of rat urine. This was characterized and identified by NMR, MS, IR, UV, Fp and ε270. After dosage with phenazone, 4,4′-dihydroxyphenazone is excreted in conjugated form by man, rabbit, guinea pig and rat. In the rat it is further shown, that conjugates of 4,4′-dihydroxyphenazone are formed by glucuronidation as well as by sulfatation. The metabolite seems to add substantially to the overall metabolic pattern of phenazone in these species. © 1979 Springer-Verlag.
