Abstract

7-(2-Hydrocarbyloxyimino- 2-(amino-thiadiazolyl) acetamido)-3-heterocyclylmethyl 3-cephem-4-carboxylate derivs. of formula (I) and their salts are new. In (I) R1 is opt. protected NH2; R2 is opt. substd. lower aliphatic hydrocarbyl or lower cycloalkenyl; and NY is an opt. substd. heterocyclic gp. contg. more than 1N. Cpds. (I) are broad-spectrum antibacterials; (II) are intermediates in their prepn. Dose is 1-1000 mg/kg daily. Specific (I) is 7-(2-ethoxyimino- 2-(5-amino-1,2,4-thiadiazol-3-yl) acetamido)-3-(3-methyl- 1-imidazoliomethyl)-3-cephem- 4-carboxylate (syn isomer) and the corresp. 3-(3-methyl-1-(1,2,3-trazolio methyl) cpd.
