RTI-7470-44 is a potent, selective, and BBB (blood-brain barrier) permeable/penetrable human trace amine-associated receptor 1 (hTAAR1) antagonist (inhibitor) with IC50 of 8.4 nM. RTI-7470-44 has moderate metabolic stability and a good preliminary off-target profile. RTI-7470-44 increases the spontaneous firing rate of dopaminergic neurons in the ventral tegmental area (VTA) of the mouse midbrain. RTI-7470-44 may be utilized in research into schizophrenia, reactive molecule addiction and Parkinson's disease (PD).

Biological Activity


ln Vitro While inhibiting benzylpiperazine (BZP) rat brain site and human sigma 2 by 75% and 90%, respectively, RTI-7470-44 (10 μM) demonstrated no off-target activity; against BZP rat brain site, it had medium affinity (Ki=1 μM) and very weak affinity to human sigma 2 (Ki=8.4 μM) [1].
ln Vivo In VTA slices of DAT-IRES-Cre; td-Tomato mice, RTI-7470-44 (40 μM) dramatically increases the firing rate of dopaminergic neurons and reverses the inhibitory effects of TAAR1 agonist RO5166017 [1]. In human liver microsomes, RTI-7470-44 (10 μM) exhibits good stability; in mouse liver microsomes, it has poor stability, and in rat liver microsomes, it has very poor stability [1]. RTI-7470-44 stability in liver microsomes from humans, rats, and mice [1]. Animal Half-life (minutes) CLINT (mL/min/mg) Rat 9.11 274 Mouse 65.8 63.5 Human 83.9 14.9

Solubility Data


Solubility (In Vitro) DMSO : ~20.83 mg/mL (~46.31 mM)
Solubility (In Vivo) Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.

Injection Formulations
(e.g. IP/IV/IM/SC)
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution 50 μL Tween 80 850 μL Saline)
*Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.
Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO 400 μLPEG300 50 μL Tween 80 450 μL Saline)
Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO 900 μL Corn oil)
Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO 900 μL (20% SBE-β-CD in saline)]
*Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).
Oral Formulation 3: Dissolved in PEG400
Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose
Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose
Oral Formulation 6: Mixing with food powders

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)

10 mM 0.2223 mL 1.1115 mL 2.2230 mL
*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.
