6-Aminopenicillanic acid 1,1-dioxide, esters thereof readily hydrolyzable in vivo, and the pharmaceutically-acceptable salts of these compounds, are useful for enhancing the effectiveness of certain β-lactam antibiotics against certain β-lactamase producing bacteria. Derivatives of 6-ammopenicillanic acid 1,1-dioxide protected by a conventional carboxy protecting group are useful intermediates to 6-aminopenicillanic acid 1,1-dioxide and esters thereof readily hydrolyzable in vivo. Processes for their preparation and pharmaceutical compositions are described.
6- 氨基青霉烷酸 1,1-二氧化物、其在体内易于水解的酯类以及这些化合物的药学上可接受的盐类,可用于提高某些 β-内酰胺类抗生素对某些产生 β-内酰胺酶的细菌的疗效。由传统羧基保护基团保护的 6-氨基青霉烷酸 1,1-二氧化物的衍生物是 6-氨基青霉烷酸 1,1-二氧化物及其酯类在体内易于水解的有用中间体。本文介绍了它们的制备工艺和药物组合物。
