title: Synthesis and vascular actions of an arachidonic acid ethylene-diamino-triethyl-ester (AA-EDTA) derivative.
abstract: An ethylene-diamino-triethyl-ester derivative of arachidonic acid (AA-EDTA) was newly synthesized and tested for its coronary vasoactivity in isolated perfused cat coronary arteries. This arachidonic acid analog exerted a coronary vasodilator effect and significantly antagonized the coronary vasoconstrictor effect of LTD4. The constrictor response to the thromboxane analog carbocyclic thromboxane A2 was unaffected by AA-EDTA. These properties of AA-EDTA may be useful in counteracting the vasoconstrictor influence of leukotrienes in situations such as coronary artery vasospasm.
