This invention provides synthetic β-lactam antibacterial compounds, a process for their preparation and pharmaceutical compositions containing them. The compounds are those of the formula (II):
wherein:
R1 is a group such that CO2R1 is a carboxylic acid group or a salt or ester thereof; and R2 is a phenyl group or a phenyl group substituted by one to four groups selected from lower alkyl, fluorine, chlorine, bromine, CN, NO2, COR3, OR3, SR3, NH2, NHCOR3, NHCO2R3, CO2R3 or CO2R1 where R3 is lower alkyl, benzyl, fluorobenzyl, chlorobenzyl, bromobenzyl or nitrobenzyl and CO2R10 is carboxyl or a salt thereof, not more than three such groups being selected from fluorine, chlorine, bromine, CN, NO2, NH2, COR3 or CO2R3 and not more than two auch groups being selected from CN, NO2 or NH2.
本发明提供了合成的β-内酰胺类抗菌化合物、其制备方法以及含有这些化合物的药物组合物。这些化合物为式(II)化合物:
其中
R1 是一个基团,使得 CO2R1 是一个羧酸基团或其盐或酯;R2是苯基或被一至四个选自低烷基、氟、氯、溴、CN、NO2、COR3、OR3、SR3、NH2、NHCOR3、NHCO2R3、CO2R3 或 CO2R1 的基团取代的苯基,其中 R3 是低烷基、苄基、氟苄基、氯苄基、溴苄基或硝基、其中 R3 为低级烷基、苄基、氟苄基、氯苄基、溴苄基或硝基,CO2R10 为羧基或其盐,其中选自氟、氯、溴、CN、NO2、NH2、COR3 或 CO2R3 的基团不超过三个,选自 CN、NO2 或 NH2 的基团不超过两个。
