Fig. 1From: First in vivo evaluation of a potential SPECT brain radiotracer for the gonadotropin releasing hormone receptora Different alpha-halogenated molecules for imaging purposes [9, 10]. b Reaction scheme for the radiolabeling of Compound-1 by using Na123I c) Competitive binding in competition of 5 nM LHRH agonist. Compound-1(C1) was evaluated in comparison with reference compound WAY207024. Compound-1 have an nM affinity for the GnRH-R and show only a drop of magnitude in affinity compared to WAY207024Back to article page
