New pyridyl derivatives of the formula ##STR1## wherein R.sub.1 to R.sub.6, A, X and n are as defined herein, the enantiomers thereof, the cis- and trans-isomers thereof if R.sub.4 and R.sub.5 together represent a carbon-carbon bond, and the addition salts thereof. The new pyridyl derivatives have antithrombotic activity and thromboxane-mediated activities. The new compounds are also simultaneously thromboxane antagonists (TRA) and thromboxane synthesis inhibitors (TSH). They also have an effect on PGE.sub.2 -production.
新的吡啶基衍生物的化学式为##STR1##其中R.sub.1至R.sub.6,A,X和n的定义如本文所述,其对映异构体,如果R.sub.4和R.sub.5一起代表碳-碳键,则其顺式和反式异构体,以及其加合盐。这些新的吡啶基衍生物具有抗血栓活性和通过血栓素介导的活性。这些新化合物同时也是血栓素拮抗剂(TRA)和血栓素合成抑制剂(TSH)。它们还对PGE.sub.2的产生产生影响。
