LY-53857 is a serotonin 5-HT2 receptor antagonist of the ergoline family which has been widely used in scientific research.[1][2][3][4]

It is a potent antagonist of the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors (Ki = 7.2–50 nM, 6.3–6.9 nM, and 7.9–8.3 nM, respectively).[1][5][6][7][8][9] The drug shows strong selectivity for the serotonin 5-HT2 receptors over the serotonin 5-HT1 and α-adrenergic receptors.[10] Although originally thought to be selective for the serotonin 5-HT2 receptors,[1] LY-53857 was subsequently found to also show significant affinity for the serotonin 5-HT7 receptor (Ki = 100 nM), where it is likewise an antagonist.[11][12] In addition, it shows high affinity for the serotonin 5-HT1F receptor (Ki = 6.87 nM).[13]

It produces antidepressant-like and anxiolytic-like effects in rodents.[3][14][15] The drug has no effect on locomotor activity by itself, but blocks the hyperlocomotion induced by phencyclidine (PCP).[19] In addition, whereas meta-chlorophenylpiperazine (mCPP) produces hypolocomotion by itself, the combination of mCPP with LY-53857 results in mCPP producing hyperlocomotion instead.[20][21] LY-53857 blocks the discriminative stimulus of the psychedelic drugs LSD, mescaline, and DOM in rodent drug discrimination studies.[9][22][23][24] The drug inhibits the hyperthermia induced by the psychedelic drug DOI, by mCPP, and by the serotonin releasing agent para-chloroamphetamine (PCA).[25][26][27]

Analogues of LY-53857 have also been described and include LY-86057 (the N1-desisopropyl analogue), LY-108742 (the N1-methyl analogue), and LY-197541 (the N1-isobutyl analogue).[28][4][29]

LY-53857 was first described in the scientific literature by 1979.[30]
