SER-082, or SDZ SER-082, is a selective serotonin 5-HT2B and 5-HT2C receptor antagonist or weak partial agonist with an ergoline-like structure which is used in scientific research. [1] [2] [3] It shows similar affinity for the serotonin 5-HT2B and 5-HT2C receptors and has ~40-fold higher affinity for the serotonin 5-HT2C receptor over the closely related serotonin 5-HT2A receptor. [1] [3]

Usages

It has been used in animal studies into the behavioural effects of the different 5-HT2 subtypes, [4] [5] [6] and how they influence the effects of other drugs such as cocaine. [7] [8] [9] The drug has been found to have no effect on anxiety in multiple paradigms in rodents. [10] In contrast to other serotonin 5-HT2C receptor antagonists, SER-082 does not produce hyperlocomotion in rodents, and instead can produce hypolocomotion at high doses that is independent of the serotonin 5-HT2C receptor. [11]

It fails to block the effects of serotonergic psychedelics in multiple behavioral paradigms, in contrast to serotonin 5-HT2A receptor antagonists. [12] [13] [14] However, the hypolocomotion induced by high doses of the phenethylamine psychedelic DOI can be attenuated by SER-082. [15] Conversely, the drug was ineffective against the hypolocomotion induced by the tryptamine psychedelic 5-MeO-DMT, whereas the serotonin 5-HT1A receptor antagonist WAY-100635 was effective. [16]

M 100907, but not the 5-HT2C/2B antagonist SER-082, can block most of the behavioral effects of DOI in the BPM paradigm, which are therefore likely mediated by activation of 5-HT2A receptors (Krebs-Thomson, Paulus, & Geyer, 1998). [...] Furthermore, 5-HT2B antagonists (e.g., SB 200,646A, SB 206,553, and SER-082) and the selective 5-HT2C antagonist SB 242,084, consistently fail to block the effects of hallucinogens in a variety of behavioral paradigms (Halberstadt et al., 2016; Ouagazzal et al., 2001; Schreiber et al., 1994; Sipes & Geyer, 1995; Smith et al., 1999; Wettstein, Host, & Hitchcock, 1999; Winter, Rice, Amorosi, & Rabin, 2007).
