Abstract
The synthesis of a series of 7 alpha-methoxy-7-[(R)-2-[3-[5-pyrimidinyl]ureido]-2-(4-hydroxyphenyl) acetamido]-3-cephem-4-carboxylates 2 is described. 7-[(R)-2-[3-[2-(p-Aminosulfonyl)-anilino-4-hydroxy-5-pyrimidinyl]ureido- 2-(4-hydroxyphenyl)acetamido]-7 alpha-methoxy-3-[(1-methyl-1H-tetrazol-5 -yl)thio]methyl-3-cephem-4-carboxylic acid, sodium salt (2k, UG-FA 132), has exhibited a broad range of antimicrobial activity. UG-FA 132 is highly active against Gram-positive and Gram-negative organisms, including Pseudomonas and lactamase producers, and shows potent activity against anaerobes. The high efficacy of UG-FA 132 was confirmed by in vivo experiments in mice.
