Product Description

Agomelatine (S20098; AGO-178; S-20098; AGO178; Valdoxan, Melitor, Thymanax) is a potent and specific agonist of MT1 and MT2 receptors with anti-depressive activity. It has an inverse relationship with the Kis of 0.1, 0.06, 0.12, and 0.27 nM for MT receptor isoforms CHO-hMT1, HEK-hMT1, CHO-hMT2, and HEK-hMT2. Developed to treat major depressive disorder (MDD), it is a special kind of antidepressant. The cloned human 5-HT2A and 5-HT1A exhibit low affinities towards it. Through blocking the inhibitory input of 5-HT2C, agomelatine increases dopamine and noradrenaline levels in in vivo studies.

Biological Activity I Assay Protocols (From Reference)
Targets
5-HT2C Receptor ( pKi = 6.4 ); 5-HT2C Receptor ( pKi = 6.2 ); hMT1 ( Ki = 0.1 nM ); hMT1 ( Ki = 0.06 nM ); hMT2 ( Ki = 0.12 nM ); hMT2 ( Ki = 0.27 nM )
ln Vitro

In vitro activity: Agomelatine partially restores decreased doublecortin expression in the hippocampus of rats exposed to repeated footshock stress and fully restores stress-affected cell survival.

ln Vivo
Agomelatine is useful in undoing the behavioral alterations in transgenic mice observed in the elevated plus maze and the Porsolt forced swim test. Additionally, after an induced phase shift, geomelatine significantly speeds up the circadian cycles of activity and temperature readjustment. Agomelatine increases neurogenesis and cell proliferation in the adult rat ventral hippocampus (VH), a region relevant to mood disorders. In adult rats, geomelatine accelerates the ratio of mature to immature neurons and increases granular cell neurite outgrowth, indicating a faster rate of maturation. Additionally, agomelatine activates a number of cellular signals, including glycogen synthase kinase 3beta, protein kinase B, and extracellular signal-regulated kinase1/2, which are known to be modulated by antidepressants and involved in the regulation of survival and proliferation. Agomelatine increases the amount of time that rats in unfamiliar pairs exposed to a new environment spend engaging in active social interaction. Consistent with the antidepressant-anxiolytic properties of Agomelatine, it increases cell proliferation and neurogenesis in the ventral dentate gyrus of rats, a region notably implicated in response to emotion. In the whole dentate gyrus of rats, geomelatine improves the survival of recently formed neurons.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
