Tri-substituted phenyl derivatives and pharmaceutical compositions containing them. In a preferred embodiment, the compounds have the general formula (2): ##STR1## wherein L is preferably --OR; R.sup.a is preferably an optionally substituted alkyl group; R is preferably an optionally substituted cycloalkyl group; R.sup.3 is preferably hydrogen; hydrogen, R.sup.4 is preferably --(CH.sub.2).sub.t Ar, --(CH.sub.2).sub.t --Ar--(L.sup.1).sub.n --Ar' or --(CH.sub.2).sub.t ArN(R.sup.b)CX.sup.1 N(R.sup.b)L.sup.2 (Alk).sub.m Ar; R.sup.5 is preferably --(CH.sub.2).sub.t Ar, --(CH.sub.2).sub.t --Ar--(L.sup.1).sub.n --Ar' or --(CH.sub.2).sub.t ArN(R.sup.b)CX.sup.1 N(R.sup.b)L.sup.2 (Alk).sub.m Ar; R.sup.6 and R.sup.7 are preferably hydrogen, L.sup.1 and L.sup.2 are preferably divalent linking groups; Ar is preferably a monocyclic or bicyclic aryl or heteroaryl group; and Ar' is preferably Ar or an Ar containing group. Compounds of the invention are potent and selective phosphodiesterase type IV inhibitors and are useful in the prophylaxis and treatment of various diseases, such as asthma, which are associated with an unwanted inflammatory response or muscular spasm.
