General description
This product is a penicilloic acid with the N-acyl group phenylacetyl as side-chain. In alkaline medium, 5R,6R-Benzylpenicilloic acid epimerizes slowly to 5S,6R-benzylpenicilloic acid until equilibrium.
Other Notes
Keep container tightly closed in a dry and well-ventilated place. Store under inert gas. Keep in a dry place.

β-Lactam antibiotics react with penicillin binding proteins (PBPs) to form relatively stable acyl-enzyme complexes. We describe structures derived from the reaction of piperacillin with PBP3 (Pseudomonas aeruginosa) including not only the anticipated acyl-enzyme complex but also an unprecedented complex with

5R,6R-Benzylpenicilloic acid was found to epimerize slowly in alkaline media to 5S,6R-benzylpenicilloic acid until equilibrium was established. Epimerization proceeded via the imine tautomer of penamaldic acid rather than the enamine form and was found to favor the 5S,6R-epimer at equilibrium.
