[Research progress of platelet activating factor(PAF) receptor antagonist]

Platelet activating factor(PAF), an endogenous synthesized phospholipid transmitter, has widely biological activities. It has "signal transmission" effect in various life processes, but abnormality of concentration in vivo will promote or aggravate the diseases, such as, cerebral ischemia, myocardial injury, multi-organ failure, asthma, injury of liver and kidney, severely affecting the normal life activities of body. In recent years, with the development of medical science and technology, more and more attention has been paid to the research of platelet activating factor receptor antagonist. Components of animals, plants, microbial fermentation, and synthetic composition all can reflect such activity. Ginkgolide B and cytopone are the most representative herbal compositions at present. This paper referred to the research status of platelet activating factor receptor antagonist in recent years, made a summary of the researches on biological effect of platelet activating factor and platelet receptor antagonist of different sources, so as to provide a reference for the exploration of effective and safe platelet activating factor receptor antagonists.
