Abstract

The compounds correspond to the formula <IMAGE> in which R<2> is hydrogen or halogen and R<3> is methyl, acetoxymethyl, carbamoylmethyl, alkoxymethyl, alkylthiomethyl, 2-carboxy-1-ethenyl or -CH2S-heterocycle. They are prepared by reacting 7 beta -amino-7 alpha -(methoxy-3-R<3>)-3-cephem-4-carboxylic acid or an alkali metal or amine salt or an ester thereof with a 2-[2-amino-5(R<2>)-4-thiazolyl]-acetic acid, the amino group of which is protected, or with a reactive functional derivative thereof; after this, the amino group and the carboxyl group, if esterified, are unblocked. Resulting 3-acetoxymethyl and 3-carbamoyloxymethyl compounds can be reacted with an alkyl mercaptan or an HS-heterocycle to give correspondingly substituted thiomethyl compounds. The compounds and their salts have a broad antimicrobial spectrum and are also particularly effective against antibiotic-resistant strains of Gram-negative bacteria; they can be used to treat infectious diseases.
