- when Z.sub.1 is phenylene, W is NR.sub.1 R.sub.2 in which R.sub.1 and R.sub.2 are independently selected from H and C.sub.1 -C.sub.4 alkyl;
- Z.sub.2 is C.sub.1 -C.sub.4 alkylene;
- Ar.sub.1 is selected from phenyl optionally substituted by one or more groups selected from halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 thioalkoxy, hydroxy, COOQ.sub.5 in which Q.sub.5 is C.sub.1 -C.sub.4 alkyl, carboxamido, cyano, amino, acetamido, nitro and trifluoromethyl; naphtyl, benzyl and cyclohexyl;
- Ar.sub.2 is pyridyl, optionally substituted by a radical selected from C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy and halogen; or a pharmaceutically acceptable acid or base salt thereof.
- 2. A compound according to claim 1 of formula I in which Ar.sub.1 is at least ortho-substituted phenyl.
- 3. A compound according to claim 1 of formula I in which Z.sub.1 is C.sub.1 -C.sub.4 alkylene, and W is NR.sub.1 R.sub.2.
- 4. A compound according to claim 1 in which Z.sub.1 is C.sub.2 -C.sub.4 alkylene, W is NR.sub.1 R.sub.2 and Ar.sub.2 is selected from 2-pyridyl and 3-pyridyl.
