title: A finding of highly selective synthetic inhibitor of plasma kallikrein; its action to bradykinin generation, intrinsic coagulation and experimental DIC.
abstract: We found a novel and highly selective synthetic inhibitor of plasma kallikrein (PK), called PKSI-527; the Ki value was 0.81 microM. PKSI-527 inhibited the bradykinin (BK) generation induced by kaolin and prolonged partial thromboplastin time (PTT). PKSI-527 prevented the decrease of fibrinogen (Fg) levels due to i.v. injection of ellagic acid in mice and ameliorated the endotoxin (ET)-induced DIC in rats.
