Compounds of the formula ##STR1## in which the index n represents an integer of from 1 to 4, the index m represents 0 or 1, X represents oxygen, sulphur or the group --NH--, W represents a group --CO--, --CO--NHSO.sub.2 -- or --SO.sub.2 NH--CO--, or X-W together represent a group --CO-- or --CO--NHSO.sub.2 --, A represents optionally substituted phenylene, thienylene or furylene, Z represents oxygen or sulphur, Y represents lower alkylene, the index k represents the value 1 or 2, R.sub.4 represents hydrogen, an optionally substituted lower aliphatic or cycloaliphatic radical or acyl, R.sub.1 represents hydrogen, lower alkyl, lower alkoxy, halogen or a group of the formula --CH.sub.2 --R.sub.2 in which R.sub.2 represents a free, esterified or etherified hydroxy or mercapto group or a quaternary ammonium group, and R.sub.3 represents hydrogen or methoxy, and in which the carboxyl groups are optionally esterified in a form that can be split under physiological conditions, and salts of such compounds having salt-forming groups, are obtained by liberating the functional group(s) in a compound of the formula I in which at least one of the functional groups present is protected. The compounds are effective in vitro and in vivo against gram-positive and gram-negative bacteria and cocci.
式为##STR1##的化合物,其中指数n表示1到4的整数,指数m表示0或1,X表示氧、硫或基团--NH--,W表示基团--CO--、--CO--NHSO.sub.2 --或--SO.sub.2 NH--CO--,或X-W一起表示基团--CO--或--CO--NHSO.sub.2 --,A表示可选择取代的苯、噻吩或呋喃基,Z表示氧或硫,Y表示低碳烷基,指数k表示值为1或2,R.sub.4表示氢、可选择取代的低脂肪或环脂肪基或酰基,R.sub.1表示氢、低烷基、低烷氧基、卤素或式--CH.sub.2 --R.sub.2的基团,其中R.sub.2表示自由、酯化或醚化的羟基或巯基或季铵基,R.sub.3表示氢或甲氧基,其中羧基在可分裂的生理条件下可选择酯化,以及具有盐基团的这种化合物的盐,是通过在式I的化合物中释放至少一种保护的官能团获得的。这些化合物在体内外对革兰氏阳性和革兰氏阴性细菌和球菌具有有效性。
