In 1969, Piper and Vane reported the discovery of a labile substance capable of stimulating contraction of rabbit aorta (rabbit aorta contracting substance, RCS). RCS was later demonstrated to be cyclooxygenase metabolite of arachidonic acid (Vargaftig and Dao, 1971; Vargaftig and Zirinis, 1973), with a half-life of approximately 30 s under physiological conditions (Svensson et al., 1975). Soon after the discovery of RCS, the production of a labile aggregation-stimulating substance (LASS) by platelets was reported (Willis, 1974). Like RCS, LASS was produced by the cyclooxygenase pathway of arachidonic acid metabolism; however, LASS had a longer half-life, suggesting that it was different from RCS.
