        <ns3:IAO_0000115>A hydrochloride salt obtained by reaction of 2-methyl-6-(phenylethynyl)pyridine with one equivalent of hydrochloric acid. Potent and highly selective non-competitive antagonist at the mGlu&lt;small&gt;&lt;sub&gt;5&lt;/sub&gt;&lt;/small&gt; receptor subtype (IC&lt;small&gt;&lt;sub&gt;50&lt;/sub&gt;&lt;/small&gt; = 36 nM) and a positive allosteric modulator at mGlu&lt;small&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;/small&gt; receptors. Centrally active following systemic administration in vivo. Reverses mechanical hyperalgesia in the inflamed rat hind paw.</ns3:IAO_0000115>
