  The synthesis and structure-activity relationships of a series of orally absorbed O-2-isocephems are described. These compounds possessed a D-[(p-hydroxyphenyl)glycyl]amino substituent at the 7-position while the substituent at the 3-position was varied. Relative to the analogous cephems, the O-2-isocephems exhibited comparable to better activity against Gram-positive organisms. Against Gram-negative organisms, their activity was variable but did indicate a lower beta-lactamase stability. Following oral administration, the O-2-isocephems generally exhibited longer half-lives but lower Cmax's and urinary recoveries.

  A series of 2-oxaisocephems with a thio-substituted methyl group at the 3-position and a [2-(5-amino-1,2,4-thiadizol-3-yl)-2-(Z)-alkoxyimino]acetamido moiety at 7-position were synthesized and tested for their antibacterial activities. The analogs 17c and 17f have well-balanced potency and significantly enhanced activity as compared with the reference compound ceftazidime. (C) 2012 Elsevier Ltd. All rights reserved.
