Compounds of formula (I):
in which Ra is a group of formula (II):
or a group of formula (III):
(where one of R' is a bond to the remainder of the compound, one more of R is R2 and the others of R' are all hydrogen), R1 is hydrogen or methyl, R2 is hydrogen, optionally substituted alkyl, halogen, hydroxy, alkoxy, amino, alkanoylamino, alkanoyloxy, alkanoyl, carboxy, alkoxycarbonyl, cyano, -S(O)jR9 (where j is 0, 1 or 2 and R9 is alkyl), or -CONR6R7 (which is optionally subsituted carbamoyl or heterocyclyl-carbonyl), R2a is hydrogen, alkyl or alkanoyl, -NR3R4 is optionally substituted amino or heterocyclic, and -COORs is carboxy, -COO-, -COOMx (where M is a cation and x is the reciprocal of the valence of the cation M) or protected carboxy and, where -COOR5 is carboxy, -COOMx or protected carboxy, the compound of formula (I) also contains an anion; ℓ, m and n are independently 0, 1, 2 or 3, provided that (m + n) is an integer from 2 to 6; p is 0, 1 or 2; Y is a single bond, oxygen, sulphur or R8N< (wherein R8 is hydrogen, alkyl or alkanoyl) and pharmaceutically acceptable salts and esters thereof are potentially valuable antibiotics.
