    摘要: Sparsomycin derivatives of the formula ##STR1## wherein X and Y are each independently an oxo or an imino group; n is 0 or the integer 1 or 2; R.sub.1 is a hydrogen or 1 to 4 carbon alkyl group; R.sub.2 is a hydrogen, a 1 to 4 carbon alkyl, a 2 to 5 carbon acyl or a benzoyl group; and R is a 1 to 6 carbon alkyl, 3 to 8 carbon alkenyl, cyanomethyl carboxymethyl, carbalkoxymethyl wherein the alkoxy moiety is a 1 to 4 carbon alkoxy group, nitromethyl, alkylcarbonylmethyl wherein the alkyl moiety is a 1 to 4 carbon alkyl group, pyridyl, furanyl, or furfuryl group or a phenyl or benzyl group optionally substituted by a methylenedioxy or one to two halogen, 1 to 4 carbon alkyl, 1 to 4 carbon alkoxy, 1 to 4 carbon alkylthio, hydroxy, nitro or cyano groups or a pharmaceutically acceptable acid addition salt thereof. Also described are their use as antiprotozoals and antibacterials.

    摘要: Disclosed are 6- and 6,6-disubstituted-2-substituted-oxapen-2-em-3-carboxylic acids of the following structure: ##STR1## wherein: R.sup.1 and R.sup.2 are independently selected from hydrogen, alkyl, alkoxyl, aralkyl, aryl, heterocyclyl and heterocyclylalkyl; R is selected from hydrogen, --OR, --SR, --NR.sub.2, alkyl, aryl, aralkyl, heterocyclyl, or heterocyclylalkyl. Such compounds and their pharmaceutically acceptable salt, and ester derivatives are useful as antibiotics. Also disclosed are processes for the preparation of such compounds, pharmaceutical compositions comprising such compounds and methods of treatment comprising administering such compounds and compositions when an antibiotic effect is indicated.
