Synthesis and antimicrobial activity of the hybrid molecules between amoxicillin and derivatives of benzoic acid
drug‐resistant pathogens in vitro and vivo. A series of hybrid molecules with a diester structure were designed and synthesized that linked amoxicillin and derivatives of benzoicacid via a methylene bridge. Synthesized compounds were evaluated for activities against Gram‐positive bacteria (Staphylococcus aureus American Type Culture Collection [ATCC] 29213, ATCC 11632; methicillin‐resistant S. aureus

New ampicillin derivatives, probenecidoxymethyl and 1-ethyl esters of ampicillin and their pharmaceutically acceptable salts, useful as antibiotics. A method for preparing these antibiotics by condensing probenecidoxymethyl or 1-ethyl halide with an acid salt of 6[D(-)-.alpha.-azidophenylacetamido] penicillanic acid, hydrogenating the azido group and isolating the product as a pharmaceutically acceptable salt of an acid. Pharmaceutical preparations containing the new antibiotics.
