Anwendungen & Verwendung
History
Antipyrine (phenazone) was one of the first important synthetic Analgesic drugs that synthesis in Germany in 1884 by a pupil of Emil Fischer.
Verwenden
Antipyrine has been used for immunoblotting. It has also been used as an internal reference marker for studying the transport characteristics of platinum-containing drug, cisplatin in the human placenta in vitro. Antipyrine is an analgesic and antipyretic that has been given by mouth and as ear drops. It is often used in testing the effects of other drugs or diseases on drug-metabolizing enzymes in the liver. (From Martindale, The Extra Pharmacopoeia, 30th ed, p29)
Herstellung & Synthese
synthetische
Antipyrine (1) was prepared from the reaction of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one with methyl iodide in methanol or in acetonitrile containing sodium bicarbonate in water in 58% yield. The reaction of 1-methyl-2-phenylhydrazine (2) with methyl 3-oxobutanoate (3) in acetonitrile gave 1 and pyrazolone 4 . Krohn has been reported the synthesis of 1 from the reaction of 5 with dimethyl sulfate in 71% yield. The reaction of pyrazolone 6 with methanol in the presence of triphenylphosphine afforded 1 (14%) and pyrazole 7 (53%). The same reaction was reported by Pegurier et al by heating the reactants in methanol containing calcium monoxide. Knorr early reported also, the synthesis of antipyrine from heating of 1-phenyl-5-ethoxy-3- methylpyrazole (8) with methyl iodide in methanol.
