Agomelatine (L(+)-Tartaric acid) is a specific agonist of MT1 and MT2 receptors (Kis: 0.1, 0.06, 0.12, and 0.27 nM for CHO-hMT1, HEK-hMT1, CHO-hMT2, and HEK-hMT2), and Agomelatine (S-20098). L(+)-Tartaric acid also functions as a selective 5-HT2C receptor antagonist (pKis: 6.4 and 6.2 at native porcine and cloned human 5-HT2C receptors), actively supporting research into melatonergic signaling pathways, receptor-mediated regulation, and novel psychiatric therapeutics by enabling precise modulation of circadian and serotonergic systems in cellular models to improve neuropharmacological understanding and experimental reproducibility across neuroscientific and clinical translational studies.

| Description | Agomelatine (L(+)-Tartaric acid) is a specific agonist of MT1 and MT2 receptors (Kis: 0.1, 0.06, 0.12, and 0.27 nM for CHO-hMT1, HEK-hMT1, CHO-hMT2, and HEK-hMT2), and Agomelatine (S-20098).

| Targets&IC50 | MT1 (human, CHO cells):0.1 nM (Ki), MT2 (human, CHO cells):0.12 nM (Ki), 5-HT2C receptor (native porcine):6.4 (pKi), MT2 (human):0.27 nM (Ki), MT1 (human):0.06 nM (ki), 5-HT2C receptor (human):6.2 (pKi) |
| In vitro | In the experimental system where human MT1 receptors (hMT1) and human MT2 receptors (hMT2) are expressed on the cell membranes of CHO cells (or HEK cells), the EC₅₀ values of Agomelatine (L(+)-Tartaric acid) acting on CHO-hMT1 and CHO-hMT2 are 1.6±0.4 nM and 0.10±0.04 nM, respectively[1]. |
| In vivo | Agomelatine (L(+)-Tartaric acid) (25, 50, or 75 mg/kg, intraperitoneal injection) exhibits antioxidant activity in strychnine- or pilocarpine-induced seizure models in mice. However, compared with the control group, Agomelatine (L(+)-Tartaric acid) did not demonstrate any antioxidant effects on oxidative stress-related indicators in pentylenetetrazole (PTZ)- or picrotoxin (PTX)-induced seizure models [3]. |

DMSO
| ||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
