title: Cardiovascular and pulmonary activity of platelet-activating factor (PAF-acether) and its derivatives.
abstract: Stereoselective synthesis and biological properties of PAF-acether, its enantiomer and some analogues of both are reported. The results clearly indicate that the ONIUM SIZE and SHAPE of the various compounds tested are important in determining guinea-pig bronchoconstriction and human platelet aggregation.
