Bicyclic derivatives of the general formula ##STR1## wherein X.sup.1 is --S-- or --SO--; X.sup.2 is --CO-- or --CS--; R.sup.1 is hydrogen, halogen or lower alkyl optionally substituted by halogen or lower alkoxy; R.sup.2 and R.sup.3 are each independently hydrogen, lower alkyl, halogen, amino, lower alkylamino, di-lower alkylamino, acylamino, lower alkexy, lower alkoxymethoxy or a group OR.sup.4 ; R.sup.4 is hydrogen or an easily hydrolyzable group; R.sup.5 is hydrogen, optionally esterified carboxy or amidated (thio)carboxy, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted acyl or heterocyclyl; R.sup.6 and R.sup.7a are each independently hydrogen or lower alkyl; R.sup.7b is hydrogen, optionally substituted hydroxy, --NR--A or --N.dbd.B, in which R is hydrogen or lower alkyl, A is hydrogen, optionally substituted alkyl, lower cycloalkyl, iminoyl, (thio)acyl, esterified carboxy or amidated (thio)carboxy and B is lower alkylidene; R.sup.7a and R.sup.7b together represent oxo, lower alkoxycarbonylmethylidene or optionally substituted hydroxyimino; and R.sup.8 is hydrogen, optionally substituted alkyl, optionally esterified carboxy or amidated (thio)carboxy; provided that no more than two of R.sup.1 -R.sup.3 are nitrogen-containing groups; no more than two of R.sup.1 -R.sup.3 are oxygen containing groups and no more than two of R.sup.1 -R.sup.3 are either nitrogen containing or oxygen containing groups; and pharmaceutically acceptable salts of the compounds of formula I carrying an acidic and/or basic substituent. The products are antimicrobially active.
