  Synthesis and in vitro antibacterial activity of 2β and 2α-(substituted methyl) phenoxymethylpenicillins and an oxidation product

  摘要：

  The effect of stereochemical changes on the antibacterial activity of a series of 2-substituted methyl-6-beta-phenoxyacetamido penams synthesized in our laboratory was studied. The 2-alpha-heteroarylthiomethyl penams were found to be more active than the 2-beta-substituted derivatives against a range of Gram-positive and Gram-negative microorganisms. Both the isomers of 2-substituted methyl derivatives were found to be less active than the unsubstituted compound, the phenoxymethyl penicillin. The oxidized product of the 2-alpha-isomer was less active than the unoxidized compound.
