F13714 is a Serotonin 5-HT1A Receptor Agonist. F13714 shows antidepressant-like properties after a single administration in the mouse model of chronic mild stress. F13714 has a high affinity (0.1 nM) and selectivity for 5-HT(1A) receptors. In vitro (18)F-F13714 binding in rats was consistent with the known 5-HT(1A) receptors distribution (hippocampus and cortical areas) and was particularly high in the dorsal raphe. In vitro binding of (18)F-F13714 was blocked in a dose-dependent fashion by WAY100635, the prototypical 5-HT(1A) antagonist, and by the endogenous agonist, serotonin (5-HT). Addition of Gpp(NH)p also inhibited in vitro (18)F-F13714 binding, consistent with a preferential binding of the compound to G-protein-coupled receptors. Ex vivo tissue measurements in rat revealed an absence of brain radioactive metabolites.
