ΓNO 3 Γ , crystallizes with two asparaginium cations and two nitrate anions in the asymmetric unit. In both asparaginium residues, protonation take place at the carboxyl O atom cis to the amine group. Cation I exists in a trans conformation, whereas cation II exhibits a gauche I conformation. A stra
No-carrier-added L-[5-11C]ornithine was synthesized in 25-40% radiochemical yield in a synthesis time of 50 min (EOB) and a specific ac vity >2.1 Ci/umol by the displacement reaction of potassium ['fC]cyanide with the functionally protected y- bromohomoserine followed by selective reduction of the [
The aim of this study is to investigate the possibility to measure ornithine decarboxylase (ODC) activity by PET. From the metabolic pathways of L-ornithine (fig. 1) can be concluded that the difference in uptake of L-[l-l4C]-ornithine (L-1-orn) and L-[5-14C]-ornithine (L-5-orn) may reflect the ODC-
