Abstract

Relates to new penicillins of the general formula <FORM:0920177/IV(a)/1> and non-toxic salts thereof, where R is a halogen atom or an alkyl group and R1 is an alkyl group, such as 2,6-dimethylphenyl- and 2-chloro-6-methylphenyl-penicillin. The compounds may be prepared by reacting 6-amino-penicillanic acid or a liqour containing 6-aminopenicillanic acid with an acid chloride, bromide, anhydride or mixed anhydride derived from a carboxylic acid of the general formula <FORM:0920177/IV(a)/2> The penicillins and their non-toxic salts may be employed in admixture with suitable pharmaceutical carriers in various medicinal dosage forms. Specification 880,400 is referred to. Reference has been directed by the Comptroller to Specification 880,400.
