ANA 12

Binding assays

Maxisorp ELISA 96-well plates were coated with various concentrations of TrkBECD-Fc, 20 mg/ml BSA, or 1 mg/ml IgG-Fc in a carbonate buffer (pH 9.6) overnight at 4°C. Plates were saturated with 0.5% BSA in PBS for 2 hours at room temperature and extensively washed in PBS-Tween 0.05%. Bodipy–ANA-12 was then incubated in 0.5% PBS-BSA for 1 hour at room temperature before the addition of BDNF in 0.5% PBS-BSA for another hour. After extensive washes in PBS-Tween 0.05%, the amount of bodipy–ANA-12 bound was quantified by fluorescence at 520 ± 10 nm.

Cell lines

PC12-TrkB cell lines

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

0-100 μM for 3 days

Applications

In the TrkB-expressing cells, ANA-12 prevented brain-derived neurotrophic factor-induced neurite outgrowth at concentrations as low as 10 nM. At concentrations up to 10–100 μM, ANA-12 completely abolished the effects of brain-derived neurotrophic factor, and no single neurite or branching could be observed.

Animal models

Mice

Dosage form

0.5 mg/kg

Application

Mice administered ANA-12 demonstrated reduced anxiety- and depression-related behaviors on a variety of tests predictive of anxiolytic and antidepressant properties in humans.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
