Abstract

The invention relates to antibacterial 7-acylamino -cephalosporanic acids of formula in which A is C1- 6 alkyl, substituted by in which A is C1- 6 alkyl, substituted by C1- 6 alkoxy, halogen C1- 6 alkoxy, halogen cycloalkyl or by one or more halogen atoms; and a salt thereof. Typical compounds are 7-[N1-(b -chloroethyl) – ureido] – cephalosporanic acid; 7 – [N1 – (11 – methyl – 21 – chloropropyl) – ureido]-cephalosporanic acid; 7-[N1-(g -chloropropyl)-ureido] -cephalosporanic acid; 7 – [N1 – (21-chloropropyl) – ureido] – cephalosporanic acid; 7 – [N1 – (11:11 – dimethyl – 21 – chloroethyl)-ureido]-cephalosporanic acid; and 7-[N1-(21:31-dichloropropyl) -ureido] – cephalosporanic acid. Salts may be alkali metal, alkaline earth metal, and tertiary organic nitrogen base salts, e.g. alkoxy, halogen C1- 6 alkoxy, halogen cycloalkyl or by one or more halogen atoms; and a salt thereof. Typical compounds are 7-[N1-(b -chloroethyl) – ureido] – cephalosporanic acid; 7 – [N1 – (11 – methyl – 21 – chloropropyl) – ureido]-cephalosporanic acid; 7 – [N1 – (21-chloropropyl) – ureido] – cephalosporanic acid; 7 – [N1 – (11:11 – dimethyl – 21 acid; and 7-[N1-(21:31-dichloropropyl) – ureido] – cephalosporanic acid. – chloroethyl)-ureido]-cephalosporanic Salts may be alkali metal, alkaline earth metal, and tertiary organic nitrogen base salts, e.g. triethylamine and N-ethylpiperidine salt. The compounds are prepared by reacting an isocyanate of formula A-N=C=O in which A has the meaning given above, with a quaternary salt of 7-amino-cephalosporanic acid with a strong organic nitrogeneous base, e.g. triethylamine. 2:2:3:3 – Tetrafluorocyclobutyl methyl isocyanate is prepared by treating 2:2:3:3-tetrafluorocyclobutylamine hydrochloride with phosgene in a solvent. The 7-acylaminocephalosporanic acids and their physiologically tolerable salts in admixture with an adjuvant may be used as tablets, dragees, capsules, solutions, suspensions, emulsions, ointments and injections.
