[3H]Ketanserin was found to label (besides a low amount of 5-HT2 receptors) non-serotonergic binding sites on human platelet membranes. The latter binding was detected in the presence of excess of the 5-HT2 antagonist BW501, and was potently inhibited by tetrabenazine.

Para-[18F]fluorobenzylguanidine ([18F]PFBG) is a newly developed tracer for imaging myocardial sympathetic neuronal innervation. This study investigated the uptake and retention mechanisms of [18F]PFBG in perfused, isolated rat heart. Fluorine-18-PFBG was administered to working rat hearts within the perfusion medium at

Inhibition of angiogenesis offers an alternative approach to cancer chemotherapy, since solid tumor growth has an absolute dependency on angiogenesis. We have previously shown that 8,9-dihydroxy-7-methyl-benzo [b]quinolizinium bromide (GPA1734) is a basement membrane synthesis inhibitor, and that this compound acts
