Cefminox sodium, MT-141, Alteporina, Tencef, Meicelin
Chemical Name: 7beta-[2-[2(S)-Amino-2-carboxyethylthio]acetamido]-7alpha-methoxy-3-(1-methyl-1H-tetrazol-5-ylthiomethyl)-3-cephem-4-carboxylic acid sodium salt
项目整合开发状态: Launched-1987
项目研究机构: Bristol-Myers Squibb (Originator), Meiji Seika (Originator), Alter (Licensee)
合成路线:The reaction of 7-beta-bromoacetamido-7-alphamethoxycephalosporanic acid (I) with D-cysteine (II) in water at pH 7 gives 7-(2-aminocarboxyethylthio)acetamido-7-alpha-methoxycephalosporanic acid (III),which is then condensed with 5-mercapto-1-methyl-1H-tetrazole (IV) in water at pH 6.5-7 and at 60 C.
