@ 6-Amidinopenicillanic acid derivatives wherein one of the nitrogen atoms of the amidino group is part of a heterocyclic ring having on a side chain an unsubstituted heterocyclic ring containing 2 to 3 nitrogen atoms, with formula:
wherein n is 0 or 1;
is a saturated 5 to 7 membered heterocyclic ring containing the nitrogen atom as the only heteroatom, said ring being unsubstituted or substituted in one or more positions with lower alkyl;
is a 5 to 7 membered heterocyclic ring having at most one additional nitrogen atom, from 0 to 2 additional double bonds, and, aside from R, either being unsubstituted or substituted in one or more positions with lower alkyl; R is lower alkyl, nitro, hydrogen,-COOH,-(CH2)y-NHR4;-(CH2)y-OR3 and
R3 is hydrogen or lower alkyl, y is an integer from 0 to 4; R, is hydrogen, lower alkyl or an amino-protecting group, (Continuation next page) R5 and R6 are hydrogen or lower alkyl and R7 is lower alkylene, hydrolyzable esters thereof, salts thereof and hydrates thereof, and with formula:
wherein n is an integer from 0 to 1; R, is hydrogen or lower alkyl;
is a saturated 5 to 7 membered heterocyclic ring containing the nitrogen atom as the only heteroatom, said ring being unsubstituted or substituted in one or more positions with lower alkyl;
is a 5 to 7 membered heterocyclic ring containing no additional double bonds or can be additionally aromatic when it is 5 membered, said ring being either unsubstituted or substituted in one or more positions with lower alkyl; and R7 is lower alkylene, hydrolyzable esters thereof, salts thereof and hydrates thereof.
These compounds are useful as antibiotics.
