Preparation of ring tritiated and of aldehyde carbon 14 labeled 1 pyrenecarboxaldehyde


, : Preparation of ring tritiated and of aldehyde carbon 14 labeled 1 pyrenecarboxaldehyde. Journal of Labelled Compounds & Radiopharmaceuticals 22(10): 1023-1032

A short, direct, and efficient synthesis of very high specific-activity ring-tritiated 1-pyrenecarboxaldehyde is described. A novel aspect of this synthesis involves direct bromination of an aromatic pyrene system carrying an electron-withdrawing aldehyde group. Synthesis of 14C-labeled 1-pyrene-carboxaldehyde is also described. Each of these compounds was converted in one step into the correspondingly radiolabelled trans-1-(2'-methoxyvinyl)pyrene.

Purpose: It is widely believed that chronic renal insufficiency (CRI) greatly increases the risk associated with endovascular abdominal aortic aneurysm repair (EVAR) and is a relative contraindication to the procedure and to the use of intra-arter...

Previous studies on asphyxia neonatorum show that the infant's blood is in a state of hypercoagulability at such a time. In the present study, we determined the amount of fibrinopeptide A (FPA) and fibrinopeptide B.beta.15-42 (FPB.beta.), new...
