Abstract: Diazepinoindoles of formula (I), ##STR1## wherein A is mono- to trisubstituted aryl or heteroaryl, and B is an --OR.sub.1 or --NR.sub.2 R.sub.3 group where R.sub.1, R.sub.2 and R.sub.3 are particularly hydrogen, and racemic forms, enantiomers and pharmaceutically acceptable salts thereof, as phosphodiesterase IV inhibitors, are disclosed.

Abstract: A 21-substituted thiosteroid represented by the general formula ##STR1## wherein R.sup.1 represents an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 or 6 carbon atoms, a phenyl group, or a benzyl group which may have a substituent on the benzene ring,R.sup.2 represents an alkanoyl group having 2 to 6 carbon atoms,R.sup.3 represents a hydrogen atom or a methyl group,X represents a hydrogen or halogen atom, andthe dotted line between 1- and 2-positions represents an optional bond. These compounds are useful an anti-inflammatory agents.
