Abstract:
The preparations of thienotriazolodiazepines bearing a substituted ethynyl group at the 2-position, and the corresponding cis-olefins and fully saturated analogues are described. The compounds were evaluated as potential antagonists of platelet-activating factor (PAF) in in vitro and in vitro test models. The new thienotriazolodiazepines are compared with known related compounds such as WEB 2086 (compound 6) and the phenylethyl derivatives 27 and 28.
