Abstract
Compounds of formula (I): ##STR1## wherein ##STR2## is a 5-membered heterocyclic group having a 6-.pi.electron system, the five ring atoms being either PA0 (a) one carbon atom and four atoms selected from carbon and nitrogen, PA0 (b) two carbon atoms, two nitrogen atoms and one atom selected from oxygen and sulphur, or PA0 (c) four carbon atoms and one atom selected from oxygen and sulphur PA0 and R.sup.1 is a substituent on a carbon or nitrogen of ##STR3## selected from C.sub.1-20 alkyl, C.sub.2-8 alkenyl aryl, aralkyl and heterocyclyl, each of which may optionally be substituted; hydrogen and C.sub.3-7 cycloalkyl, PA0 and, where appropriate, R.sup.2 is a substituent on a carbon or nitrogen of ##STR4## and when present is the same or different to R.sup.1 and is selected from C.sub.1-20 alkyl, C.sub.2-8 alkenyl, aryl, aralkyl and heterocyclyl each of which may optionally be substituted; hydrogen and C.sub.3-7 cycloalkyl, have antibacterial and antimycoplasmal activity.
