(3-Chloro-4-fluorophenyl)-(4-fluoro-4-{[(5-methyl-6-methylaminopyridin-2-ylmethyl)amino]methyl}piperidin-1-yl)methanone, 1-(3-Chloro-4-fluorobenzoyl)-4-fluoro-N-[[5-methyl-6-(methylamino)-2-pyridinyl]methyl]-4-piperidinemethanamine, F 13714, F13714
F13714 is an orally active, high-affinity, potent, biased serotonin receptor 5-HT1A agonist (pKi = 10.12 against 0.2 nM (±)-8-OH-DPAT binding to rat cortex tissue). F13714 inhibits 100 μM forskolin-induced cAMP accumulation in human 5-HT1A-expressing HeLa cells (pIC50 = 8.67) and displays antidepressant efficacy in vivo (ED50 = 0.05 mg/kg p.o., Emax >80%; rat forced swimming). F13714 and F15599 display differential biased agonism and, when administerd in vivo, F13714 preferentially activates raphe-located autoreceptors, while F15599 preferentially activates post-synaptic heteroreceptors.
Orally active, high-affinity, potent, biased serotonin receptor 5-HT1A agonist with a differential mode of action as F15599 in vitro and in vivo.
Peak-dose dyskinesia is associated with the dramatic increase in striatal dopamine levels that follows L-DOPA administration. The 'false neurotransmitter' hypothesis postulates that the latter is likely due to an aberrant processing of L-DOPA by serotonergic neurons. In keeping with this
Serotonin 5-HT1A receptor agonists reduce L-DOPA-induced dyskinesia (LID) in animal models of Parkinson's disease (PD). Here, we compared the effects of novel 5-HT1A receptor 'biased agonists' on LID in hemiparkinsonian rats. F13714 preferentially activates pre-synaptic 5-HT1A autoreceptors. F15599 preferentially activates

The aim of this work was to improve the oral bioavailability of a recently discovered, novel structural class of 5-HT1A receptor agonists: aryl-{[4-(6-R-pyridin-2-ylmethyl)-amino]-methyl}-piperidin-1 -yl-metha none. Incorporation of a fluorine atom in the beta-position to the amino function in the side
The subject of the present study was the functional and pharmacological characterization of human 5-HT(1A) receptor regulation of ion channels in Xenopus oocytes. Activation of the heterologously expressed human 5-HT(1A) receptor induced two distinct currents in Xenopus oocytes, consisting of
The serotonin (5-HT) deficiency hypothesis of aggression is being seriously challenged by pharmacological data showing robust anti-aggressive effects of 5-HT1A receptor agonists in dose ranges that concomitantly inhibit 5-HT neurotransmission. Hence, an adequate interpretation of the role of 5-HT activity
