Patent ID: 7998972

Claim:
A compound of the formula I wherein each of x and y is, independently of the other, 0 or 1, R 1 is phenyl or phenyl-lower alkyl, each of which, in the phenyl moiety, is substituted by up to three moieties independently selected from halo-lower alkyl, especially trifluoromethyl, hydroxy, C 6 -C 14 -aryl, especially phenyl, amino, amino-lower alkyl, especially aminomethyl or 2-aminoethyl, amidino, N-hydroxy-amidino, amidino-lower alkyl, such as 2-amidinoethyl, N-hydroxyamidino-lower alkyl, especially N-hydroxy-amidino-methyl or -2-ethyl, cyano-lower alkyl, especially cyanomethyl, and cyano; or is C 3 -C 8 -cycloalkyl, especially cyclohexyl, or hydroxy-C 3 -C 8 -cycloalkyl, especially hydroxy-cyclohexyl; X is C═O or C═S with the proviso that then the dashed line bonding X to N is absent, so that X is bound to the adjacent N via a single bond and with the proviso that then y is 1 and R is hydrogen or an organic moiety that can be bound to nitrogen; and at least one but not more than two of R 2 , R 3 , R 4 , R 5 and R 6 , independently of the others, is an organic moiety or an inorganic moiety, the remainder being hydrogen; wherein the organic moiety is selected from an unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkinyl, unsubstituted or substituted aryl, unsubstituted or substituted heterocyclyl, unsubstituted or substituted cycloalkyl or unsubstituted or substituted cycloalkenyl, unsubstituted or substituted arylcarbonylamino, amino substituted by one or two moieties selected from the group consisting of lower alkyl, substituted lower alkyl moieties, aryl, cycloalkyl and mercapto-lower alkyl, alkyloxy or cyano; and wherein the inorganic moiety is selected from halogen, hydroxy, amino, or nitro; provided that R 3 is hydrogen, lower alkyl, especially ethyl, halo, especially fluoro, chloro or bromo, lower alkoxy, especially methoxy, or unsubstituted or substituted C 6 -C 14 -aryl, especially phenyl, hydroxyphenyl or methoxyphenyl or a pharmaceutically acceptable salt thereof.
