GR-55562 is a selective serotonin 5-HT1B and 5-HT1D receptor antagonist.[1] It is one of several selective serotonin 5-HT1B receptor antagonists used in scientific research.[2][3]

The drug is a silent antagonist of the serotonin 5-HT1B receptor, unlike the related agent GR-127935.[1][4] GR-55562 has around 10-fold selectivity for the serotonin 5-HT1B receptor over the serotonin 5-HT1D receptor and has only weak affinity for a number of other serotonin receptors.[4]

It is ineffective in attenuating MDMA-induced prosocial behavior in animals.[5][6] Conversely, the serotonin 5-HT1A receptor antagonist WAY-100635 can abolish MDMA-induced prosocial behavior.[5][6]

ISSN 1354-3776. However, as mentioned above, it was later found that GR-127935 is not a silent antagonist at human 5- HT1B/1D sites. More recent investigations from Glaxo and others have shown that, unlike GR-127935, GR55562 could be characterised as a silent, potent and selective h5-HT1B receptor antagonist [43]. However, so far no results have been disclosed concerning the ability of this particular compound to antagonise central presynaptic 5-HT1B receptors upon systemic administration.
