Latamoxef was synthesized by Shionogi Pharmaceuticals in 1975 starting with benzylpenicillin and using a novel drug design. The oxacephem nucleus, in which the sulfur atom had been replaced by oxygen, was substituted with a methoxyl group at the 7α position, as in the cephamycins. A carboxyl moiety and a hydroxybenzyl group were added at the 7β position, as in carbenicillin, and a methyltetrazolylthiomethyl group was attached at the 3 position. These substitutions resulted in a strong activity against gram-negative bacteria and a high resistance to the action of βlactamase, along with excellent activity against Pseudomonas aeruginosa, even though the compound has no activity against Staphylococcus aureus.
