Pharmacological profile of TCV-309--a potent PAF antagonist

TCV-309 potently and specifically inhibited the diverse biological actions of PAF such as platelet aggregation, hypotension, increased vascular permeability, bronchoconstriction and death. TCV-309 did not cause hemolysis or vascular irritation. TCV-309 showed beneficial effects on experimental endotoxic shock, anaphylactic shock and disseminated intravascular coagulation.
