Effects of two tetrahydroisoquinolines (YS-49 and YS-51) on experimental disseminated intravascular coagulation induced by lipopolysaccharide in rats.

| Abstract |
Disseminated intravascular coagulation (DIC) is a pathological syndrome, which occurs following the uncontrolled widespread activation of blood coagulation, resulting in the intravascular formation of fibrin, which may lead to thrombotic occlusion of small and midsize vessels. The effects of 1-(alpha-naphthylmethyl)-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline (YS-49, CAS 132836-42-1) and 1-(beta-naphthylmethyl)-6,7-dihydroxy-1,2,3,4-tetra-hydroisoquinoline (YS-51, CAS 213179-96-5) on the experimental DIC induced by lipopolysaccharide (LPS) in rats, were investigated. The oral administration of YS-49 and YS-51 (10 or 50 mg/kg) attenuated the dramatic increase of serum fibrinogen/fibrin degradation product (FDP) level, the decrease of plasma fibrinogen concentration and the number of platelets in blood and the prolongation of prothrombin time (PT) and activated partial thromboplastin time (aPTT) induced by LPS. The liver and kidney function parameters, aspartate amino-transferase (AST) and blood urea nitrogen (BUN), were also improved with YS-49 and YS-51. The above results suggest that YS-49 and YS-51 have therapeutic potential for DIC and/or accompanying multiple organ failure.
