(S)-WAY 100135 dihydrochloride is a potent and selective antagonist of 5-HT1A receptor with IC50 value of 15 nM.
The 5-HT1A receptor is a G protein-coupled receptor for endogenous neurotransmitter serotonin (5-HT) and mediates inhibitory neurotransmission.
(S)-WAY 100135 dihydrochloride is a potent and selective somatodendritic and postsynaptic 5-HT1A receptors antagonist. (+/-)-WAY100135 inhibited 5-HT1A receptor in the rat hippocampal with IC50 value of 34 nM [1].
In the murine elevated plus-maze test, (S)-WAY 100135 (10 mg/kg) exhibited anxiolytic-like effects [2]. In free feeding rats, WAY-100135 (3 mg/kg) significantly inhibited hyperphagia and the increased incidence of feeding induced by 8-OH-DPAT (0.1 mg/kg), which was mediated by somatodendritic 5-HT1A autoreceptor [3]. In rats, (S)-WAY 100135 (0.2, 1, 5 ug/ul) inhibited the impairment of choice accuracy induced by intrahippocampal scopolamine (3.75 ug/ul) in a dose-dependent way. However, (S)-WAY 100135 didn’t influence the acquisition of spatial learning [4]. In rats, WAY-100135 (10.0 mg/kg) inhibited the decrease of 5-HT release induced by buspirone, a 5-HT1A receptor partial agonist [5].

Anxiolytic-like effect of (S)-WAY 100135, a 5-HT1A receptor antagonist, in the murine elevated plus-maze test.[Pubmed:7813555]
Eur J Pharmacol. 1994 Aug 22;261(3):321-5.
The effects of (S)-WAY 100135 ((S)-N-tert-butyl-3-(4-(2-methoxyphenyl)- piperazin-1-yl)-2-phenyl-propanamide dihydrochloride; 2.5-20.0 mg/kg), a 5-HT1A receptor antagonist, on the behaviour of male mice were examined in the elevated plus-maze test of anxiety. An ethological scoring technique was used to provide a comprehensive profile of drug action. Only minor changes in behaviour were observed at 2.5 and 5.0 mg/kg, and consisted of reductions in some (though not all) risk assessment measures. At 10 mg/kg, the compound increased percent open arm entries and percent open arm time, without altering general activity levels. This classic anxiolytic-like profile was confirmed by major reductions in risk assessment measures including protected head-dips and protected stretched attend postures. Although many of the same changes were also observed at 20 mg/kg, the absence of an effect on percent open arm time and a tendency towards increased non-exploratory behaviour suggested (1) some loss of anxiolytic activity and (2) a possible contribution of non-specific factors at higher doses. Present findings indicate that (S)-WAY 100135 produces clear anxiolytic-like effects in the murine elevated plus-maze, a profile that can be distinguished from that produced by 5-HT1A receptor partial agonists in the same test.
WAY100135: a novel, selective antagonist at presynaptic and postsynaptic 5-HT1A receptors.[Pubmed:8365456]
Eur J Pharmacol. 1993 Jun 24;237(2-3):283-91.
The novel phenylpiperazine derivative, (+/-)-WAY100135 (N-tert-butyl-3-(4-(2-methoxyphenyl)piperazin-1-yl)-2-phenylpro pionamide dihydrochloride), is a selective antagonist at both somatodendritic and postsynaptic 5-HT1A receptors. The IC50 of (+/-)-WAY100135 at the rat hippocampal 5-HT1A receptor was 34 nM, whereas its IC50 at a range of other receptor sites was > 2 microM. Up to a dose of 2.5 mg/kg i.v. (+/-)-WAY100135 induced a maximum 30% inhibition of raphe neuronal firing and (at 0.5 mg/kg i.v.) antagonised the inhibition of firing induced by 8-OH-DPAT (8-hydroxy-2-(di-n-propylamino)tetralin) in anaesthetised rats. (+/-)-WAY100135 antagonised the action of 5-carboxamidoiodotryptamine in the guinea-pig ileum, with a pA2 of 7.2. (+/-)-WAY100135 had no agonist-like behavioural effects but antagonised the behavioural syndrome and hypothermia induced by 8-OH-DPAT in the rat and mouse, respectively. The interaction of (+/-)-WAY100135 with the 5-HT1A receptor was stereoselective; the (+)-enantiomer being markedly more active in binding, functional and behavioural studies. These data indicate that (+/-)-WAY100135 is the first highly selective antagonist at both somatodendritic and postsynaptic 5-HT1A receptors.
Silent 5-HT1A receptor antagonists: utility as research tools and therapeutic agents.[Pubmed:8122313]
Trends Pharmacol Sci. 1993 Dec;14(12):41-8.
The 5-hydroxytryptamine 5-HT1A receptor has been the focus of considerable research effort for over a decade. However, the definitive classification of this receptor and the full characterization of its pharmacology have awaited the development of highly selective 5-HT1A receptor antagonists. The only compounds available until recently have been either nonselective or partial 5-HT1A receptor agonists (or a combination of both). Confusion has arisen owing to the use of different pharmacological models in examining the functional activity of 5-HT1A receptor ligands. Several partial agonists display only antagonist activity in models of postsynaptic 5-HT1A receptor function, whereas their agonist properties are revealed in models of presynaptic, somatodendritic 5-HT1A autoreceptor function. In view of these considerations, the term 'silent antagonist' has been introduced to distinguish true 5-HT1A receptor antagonists from partial agonists. Allan Fletcher and colleagues review the pharmacological properties of the first selective silent 5-HT1A receptor antagonists that have been recently discovered and discuss the potential therapeutic utility of these novel compounds.
