Claims
- 1. A compound having the formula ##STR411## wherein A is C.sub.1 -C.sub.6 straight or branched chain alkylene; R.sup.2 is hydrogen, an anionic charge or a conventional readily removable carboxyl protecting group, providing that when R.sup.2 is hydrogen or a protecting group, there is also present a counter ion; and ##STR412## represents a radical of the formula ##STR413## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein available ring carbon atoms are optionally substituted by 1-3 substituents independently selected from C.sub.1 -C.sub.4 alkyl; ##STR414## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein available ring carbon atoms are optionally substituted by 1 or 2 substituents independently selected from C.sub.1 --C.sub.4 alkyl; or ##STR415## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein an available ring carbon atom is optionally substituted by C.sub.1 -C.sub.4 alkyl; or a pharmaceutically acceptable salt thereof.
- 2. A compound according to claim 1 in which ##STR416## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein an available ring carbon atom is optionally substituted by C.sub.1 -C.sub.4 alkyl.
- 3. A compound according to claim 1 in which ##STR417## wherein R.sup.5 is C.sub.1 -C.sub.4 alkyl.
- 4. A compound according to claim 1 in which ##STR418##
- 5. A compound having the formula ##STR419## wherein A is C.sub.1 -C.sub.6 straight or branched chain alkylene; R.sup.2 is hydrogen, an anionic charge or a conventional readily removable carboxyl protecting group, providing that when R.sup.2 is hydrogen or a protecting group, there is also present a counter ion; and ##STR420## represents a radical of the formula ##STR421## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein available ring carbon atoms are optionally substituted by 1-3 substituents independently selected from C.sub.1 -C.sub.4 alkyl; ##STR422## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein available ring carbon atoms are optionally substituted by 1 or 2 substituents independently selected from C.sub.1 -C.sub.4 alkyl; or ##STR423## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein an available ring carbon atom is optionally substituted by C.sub.1 -C.sub.4 alkyl; or a pharmaceutically acceptable salt thereof.
- 6. A compound according to claim 5 in which ##STR424## wherein R.sup.5 is C.sub.1 -C.sub.6 alkyl and wherein an available ring carbon atom is optionally substituted by C.sub.1 -C.sub.4 alkyl.
- 7. A compound according to claim 5 in which ##STR425## wherein R.sup.5 is C.sub.1 -C.sub.4 alkyl.
- 8. A compound according to claim 5 in which ##STR426##
- 9. A compound of the formula ##STR427## wherein R.sup.2 is hydrogen, an anionic charge or a conventional readily removable carboxyl protecting group, providing that when R.sup.2 is hydrogen or a protecting group, there is also present a counter ion; or a pharmaceutically acceptable salt thereof.
- 10. A compound of the formula ##STR428## wherein R.sup.2 is hydrogen, an anionic charge or a conventional readily removable carboxyl protecting group, providing that when R.sup.2 is hydrogen or a protecting group, there is also present a counter ion; or a pharmaceutically acceptable salt thereof.
