Characterization of the Activity of a Platelet Activating Factor Antagonist, CV-3988

[摘要] References(18)Cited-By(4)CV-3988 inhibited the vascular permeability increase induced by C16-PAF and C18-PAF in rat skin in a dose-dependent manner. The inhibition was shown to be specific and competitive with PAF on its receptor by the following observations: 1) Parallel shift of the dose-response curve; 2) Crossing of double reciprocal plots on the intersection of the ordinate; and 3) No inhibition on other autacoids such as bradykinin, histamine, 5-hydroxytryptamine and LTC4. PAF-induced blood pressure fall in rats was also suppressed by pretreatment with CV-3988 selectively.
