Pyridine derivatives of formula ##STR1## their heteroaromatic N-oxides and their pharmaceutically acceptable acid addition salts are disclosed. In the formula z is 0, 1 and 2; R is hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, trifluoromethyl, nitro, amino, (lower)alkylamino or di(lower)alkylamino; R.sup.1 is hydrogen or lower alkyl; R.sup.2 is --(CH.sub.2).sub.n --R.sup.3 or --CH.sub.2 --CH.dbd.CH--(CH.sub.2).sub.m --R.sup.3 or --CH.sub.2.C.tbd.C.(CH.sub.2).sub.m --R.sup.3 where n is 1 to 6, and m is 0 to 3; and R.sup.3 is a ring of formula ##STR2## The compounds exhibit activity as 5-HT.sub.1A agonists, antagonists or partial agonists and are used for the treatment of CNS disorders, e.g. anxiety, as antihypertensives and in treating anorexia.
