Abstract

Relates to penicillins of the formula <FORM:0924612/IV(a)/1> wherein R1 and R2, which are different, stand for alkyl, aryl or aralkyl radicals, optionally substituted, and the salts thereof. The Specification contains many examples of penicillins of the above formula, of which the following are typical: 6-(O-2-chlorophenyl-O1- methylphosphoramidyl) - penicillanic acid 6(O-methyl-O1-2-chloroethylphosphoramidyl)-penicillanic acid and 6-(O-2-chlorophenyl-O1- cyclohexylphosphoramidyl) -penicillanic acid. The penicillins may be made by the interaction of 6-aminopenicillanic acid with a phosphoric acid derivative of the formula <FORM:0924612/IV(a)/2> wherein X stands for a halogen atom such as chlorine. The following phosphorochloridate derivatives are obtained by the interaction of the corresponding aromatic phosphorodichloridate derivative with the corresponding alcohol: 2-chlorophenyl 2-methoxy-ethyl, 2-chlorophenyl cyclohexyl-, 4-methoxycarbonylphenyl isopropyl-, 3-tolyl methyl- and 3-tolyl ethyl-phosphorochloridates. 2-Chlorophenyl methyl phosphorochloridate may be prepared by reacting sodium methoxide with 2-chlorophenyl phosphorodichloridate. 2-Methoxycarbonylphenyl methyl and 2-isopropoxycarbonylphenyl isopropyl phosphorochloridates are prepared by the action of methanol and isopropanol respectively on 2- chlorocarbonylphenyl phosphorodichloridate. 4- Methoxycarbonylphenyl phosphorodichloridate may be prepared by reacting methyl p-hydroxybenzoate with phosphorus oxychloride in the presence of magnesium.ALSO:Pharmaceutical compositions comprise one or more penicillins of the formula <FORM:0924612/VI/1> wherein R1 and R2, which are different, stand for alkyl, aryl or aralkyl radicals, optionally substituted (see Group IV (b)) or a non-toxic salt thereof, in admixture with an inert non-toxic diluent or carrier. The compositions may also contain at least one known penicillin or a non-toxic salt thereof. The compositions may be in any of the forms suitable for penicillin therapy such as tablets, granules, capsules, dispersible powders for the preparation of aqueous dispersions, solutions, suspensions, emulsions or ointments.
