5-ht1a modulator 1

5-HT1A modulator 1 is a small molecule modulator, a high-affinity multi-target ligand with potent inhibitory activity against 5-HT1A receptor (IC50=2 nM), α1-adrenergic receptor (IC50=10 nM), and dopamine D2 receptor (IC50=40 nM). This compound is primarily used for research on neuropsychiatric disorders such as anxiety, depression, or schizophrenia.

5-HT1A modulator 2 hydrochloride, a derivative of 8-OH-DPAT, is a modulator of 5-HT1A with a Ki of 53 nM for 5-HT1A binding [1]. [1]. Naiman, N., et al. 2-(Alkylamino)tetralin derivatives: interaction with 5-HT1A serotonin binding sites. Journal of Medicinal Chemistry, 1989; 32(1), 253-256.

5-HT1A modulator 4 (Compound 1) is a ligand for the 5-HT receptor, with Ki values of 2.18 μM for 5-HT1A and 19.7 μM for 5-HT2A.

D3/5-HT receptor modulator-1 (compound 5i) is a selective antagonist of the dopamine D3 and 5-HT2A receptors, and a partial agonist at the 5-HT1A receptor. It exhibits Ki values of 4.5 nM, 11.9 nM, and 15.3 nM for the dopamine D3, 5-HT2A, and 5-HT1A receptors respectively. The compound shows lower affinity for the dopamine D2 receptor, 5-HT2C receptor, and hERG channel. D3/5-HT receptor modulator-1 possesses atypical antipsychotic properties.

1-(1-Naphthyl)piperazine is a modulator of 5-HT receptors, acting both as a 5-HT2A receptor antagonist and a 5-HT1A receptor agonist, with a human 5-HT6 receptor binding constant (Ki) of 120 nM. It partially inhibits forskolin-stimulated adenylate cyclase activity in bovine substantia nigra and can suppress UV radiation-induced immunosuppression. Additionally, 1-(1-Naphthyl)piperazine induces S-phase cell cycle delay, apoptosis, and increases reactive oxygen species (ROS) levels, leading to the inhibition of MNT-1 cell proliferation. This compound is utilized in melanoma research.
