The invention concerns ether derivatives of the formula I Q.sup.1 --X--Ar--Q.sup.2 I wherein Q.sup.1 is an optionally substituted 9-, 10- or 11-membered bicyclic heterocyclic moiety containing one or two nitrogen heteroatoms and optionally containing a further heteroatom selected from nitrogen, oxygen and sulphur; X is oxy, thio, sulphinyl or sulphonyl; Ar is optionally substituted phenylene, pyridinediyl, pyrimidinediyl, thiophenediyl, furandiyl, thiazolediyl, oxazoiediyl, thiadiazoiediyl or oxadiazolediyl; and Q.sup.2 is selected from the groups of the formulae II and III: ##STR1## wherein R.sup.1 is hydrogen, (2-5C)alkanoyl or optionally substituted benzoyl; R.sup.2 is (1-4C)alkyl; and R.sup.3 is hydrogen or (1-4C)alkyl; or R.sup.2 and R.sup.3 are linked to form a methylene, vinylene, ethylene or trimethylene group; or a pharmaceutically-acceptable salt thereof; processes for their preparation; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors.
A Fas ligand solubilization inhibitor which comprises, as the active ingredient, a compound of the generic formula (I) having a matrix metalloproteinase inhibitory activity or its pharmaceutically acceptable salt. The drug is useful in the prevention or treatment of diseases caused by solubilized Fas ligand, such as hepatitis, GVHD, AIDS, autoimmune diseases, etc.

An acylphenylglycine derivative represented by general formula (I) or a pharmaceutically acceptable salt thereof, and a preventive and remedy for diseases caused by an increased collagenase activity containing the same as the active ingredient, wherein R¹ represents hydrogen atom, methyl, methylaminomethyl or morpholinomethyl; R² represents hydrogen atom, hydroxy, fluorine atom, or C₁-C₄ linear or branched alkyl; and R³ represents C₁-C₄ linear or branched alkyl. The compound (I) and the salt maintains a potent collagenase inhibitor activity in the blood for long after being administered, and are useful as a remedy for various diseases believed to be caused by an increased collagenase activity.
