    摘要: 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.
