摘要:
The compounds are of the class of esters of 7-[2-(2-aminothiazol-4-yl-)-2-(syn)methoxyiminoacetamido] cephalosporin derivatives, including lower alkoxymethyl, .alpha.-lower alkoxy-.alpha.-substituted methyl, lower alkylthiomethyl, acyloxymethyl, ethoxycarbonyloxy-1-methylmethyl and .alpha.- acyloxy-.alpha.-substituted methyl esters. The compounds are useful against a broad spectrum of bacteria, particularly gram-negative bacteria, and may be administered in the form of injections, capsules, tablets and granules.
