The (S)-enantiomer of 5-fluoro-8-hydroxy-2-(dipropylamino) tetralin [(S)-2a; (S)-UH301] was the first reported 5-HT1A receptor antagonist. We now give a full account on the synthetic effort leading to the preparation of the racemate and the enantiomers of 2a. The crystal and molecular...

The effects of the selective 5-HT1A receptor agonist (R)-8-hydroxy-2(di-n-propylamino)tetralin [(R)-8-OH-DPAT] and the novel 5-HT1A antagonist (S)-5-fluoro-8-hydroxy-2-(dipropylamino)-tetralin [(S)-UH-301] were studied with regard to the firing pattern of single mesencephalic dopamine (DA) neurons with extracellular recording techniques in chloral hydrate anesthetized male...

The 5-HT1A-receptor antagonist (S)-UH-301 (S)-5-fluoro-8-hydroxy-2- (dipropylamino)tetralin) completely antagonized the hypotension and bradycardia induced by (R) = 8-OH DPAT [R)-8-hydroxy-2- (dipropylamino)tetralin) in conscious rats. (S)-UH-301 alone induced a weak hypertension, which might be due to its 5-HT1A-receptor antagonistic properties. (R)-UH-301 induced...

The receptor-mediated control of brain monoamine synthesis was used to examine the in vivo intrinsic efficacy of the 5-HT1A receptor antagonists NAD-299, S(-)-UH-301 and WAY-100,635. The rate of monoamine synthesis was estimated by measuring the accumulation of DOPA and 5-HTP...

The selective 5-hydroxytryptamine (5-HT1A) receptor agonist 8-hydroxy-2-(dipropylamino)tetralin (8-OH-DPAT) induces a large number of pharmacological effects. In the present study we demonstrate that a novel 8-OH-DPAT analog, (S)-5-fluoro-8-hydroxy-2-(dipropylamino)tetralin [(S)-UH-301], is able to antagonize completely the following (R)-8-OH-DPAT-induced effects in the rat:...
