abstract | 1473672 Cephalosporin derivatives FUJISAWA PHARMACEUTICAL CO Ltd 9 May 1974 [10 May 1973 6 July 1973 3 Dec 1973 10 Jan 1974 7 Feb 1974 8 Feb 1974 27 March 1974] 20637/74 Heading C2C Novel compounds I (in which R 1 is NO 2 , alkoxy, alkylsulphonamido, or alkylaminosulphonamido; R 2 is H or OH and must be OH if R 1 is NO 2 or alkoxy; R 3 is H or optionally alkylated heterocyclylthio provided R 3 is H if R 1 is alkoxy and R 2 is OH; X is amino or protected amino and M is H or a non-toxic cation) and their derivatives at the carboxyl group are prepared by reaction of a compound II with a compound III or by reaction of a compound IV in which R 3 <SP>11</SP> is alkanoyl and R 1 <SP>1</SP> is as R 1 except that it may not be alkoxy, with a thiol R 3 <SP>1</SP>H in which R 3 <SP>1</SP> is heterocyclylthio. Pharmaceutical compositions having antibacterial properties comprise a compound I together with a suitable carrier or diluent. |
