摘要：

The synthesis and the inhibitory activity against beta-lactamase 1 from Bacillus cercus is described Tor a new series of 6 alpha-bromo, chloro or fluoro-2 beta-chloromethyl-2 alpha-methylpenam-3 alpha-carboxylic acids (5a-c) and their corresponding sulfones 6a-c and 6 alpha-bromo, chloro or fluoro-2 beta-mercaptobenzothiazolylmethyl-2 alpha- methylpenam-3 alpha-carboxylic acids (8a-c). Among the novel compounds, the highest activity was expressed by 6 alpha-chloro-2 beta-chloromethyl-2 alpha-methylpenam-3 alpha-carboxylic acid 1,1-dioxide (6b).
