Abstract

A potential PET imagining agent for prostate and prostate derived tumors, N-3-[18F]fluoropropylputrescine, has been prepared. The radiochemical yield was 7-10% at end-of-synthesis (EOS) and the specific activity was greater than 1.1 Ci/mumol (overall synthesis time was 1.5 hr). In vivo biodistribution in mature male rats showed high prostate uptake. In rats that were pretreated with alpha-difluoromethylornithine and dihydrotestosterone propionate, the prostate to muscle ratio and prostate to blood ratio increased significantly. This high target uptake and target to nontarget ratio indicates the potential of this compound as a prostate imaging agent.

African trypanosomiasis, also known as sleeping sickness, is an insect-borne parasitic disease of humans and other animals. It is caused by protozoa of the species Trypanosoma brucei and almost invariably progresses to death unless treated. Discover the latest research on African trypanosomiasis here.
